+ // Big Integer Library v. 5.5
+ // Created 2000, last modified 2013
+ // Leemon Baird
+ // www.leemon.com
+ //
+ // Version history:
+ // v 5.5 17 Mar 2013
+ // - two lines of a form like "if (x<0) x+=n" had the "if" changed to "while" to
+ // handle the case when x<-n. (Thanks to James Ansell for finding that bug)
+ // v 5.4 3 Oct 2009
+ // - added "var i" to greaterShift() so i is not global. (Thanks to Péter Szabó for finding that bug)
+ //
+ // v 5.3 21 Sep 2009
+ // - added randProbPrime(k) for probable primes
+ // - unrolled loop in mont_ (slightly faster)
+ // - millerRabin now takes a bigInt parameter rather than an int
+ //
+ // v 5.2 15 Sep 2009
+ // - fixed capitalization in call to int2bigInt in randBigInt
+ // (thanks to Emili Evripidou, Reinhold Behringer, and Samuel Macaleese for finding that bug)
+ //
+ // v 5.1 8 Oct 2007
+ // - renamed inverseModInt_ to inverseModInt since it doesn't change its parameters
+ // - added functions GCD and randBigInt, which call GCD_ and randBigInt_
+ // - fixed a bug found by Rob Visser (see comment with his name below)
+ // - improved comments
+ //
+ // This file is public domain. You can use it for any purpose without restriction.
+ // I do not guarantee that it is correct, so use it at your own risk. If you use
+ // it for something interesting, I'd appreciate hearing about it. If you find
+ // any bugs or make any improvements, I'd appreciate hearing about those too.
+ // It would also be nice if my name and URL were left in the comments. But none
+ // of that is required.
+ //
+ // This code defines a bigInt library for arbitrary-precision integers.
+ // A bigInt is an array of integers storing the value in chunks of bpe bits,
+ // little endian (buff[0] is the least significant word).
+ // Negative bigInts are stored two's complement. Almost all the functions treat
+ // bigInts as nonnegative. The few that view them as two's complement say so
+ // in their comments. Some functions assume their parameters have at least one
+ // leading zero element. Functions with an underscore at the end of the name put
+ // their answer into one of the arrays passed in, and have unpredictable behavior
+ // in case of overflow, so the caller must make sure the arrays are big enough to
+ // hold the answer. But the average user should never have to call any of the
+ // underscored functions. Each important underscored function has a wrapper function
+ // of the same name without the underscore that takes care of the details for you.
+ // For each underscored function where a parameter is modified, that same variable
+ // must not be used as another argument too. So, you cannot square x by doing
+ // multMod_(x,x,n). You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
+ // Or simply use the multMod(x,x,n) function without the underscore, where
+ // such issues never arise, because non-underscored functions never change
+ // their parameters; they always allocate new memory for the answer that is returned.
+ //
+ // These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
+ // For most functions, if it needs a BigInt as a local variable it will actually use
+ // a global, and will only allocate to it only when it's not the right size. This ensures
+ // that when a function is called repeatedly with same-sized parameters, it only allocates
+ // memory on the first call.
+ //
+ // Note that for cryptographic purposes, the calls to Math.random() must
+ // be replaced with calls to a better pseudorandom number generator.
+ //
+ // In the following, "bigInt" means a bigInt with at least one leading zero element,
+ // and "integer" means a nonnegative integer less than radix. In some cases, integer
+ // can be negative. Negative bigInts are 2s complement.
+ //
+ // The following functions do not modify their inputs.
+ // Those returning a bigInt, string, or Array will dynamically allocate memory for that value.
+ // Those returning a boolean will return the integer 0 (false) or 1 (true).
+ // Those returning boolean or int will not allocate memory except possibly on the first
+ // time they're called with a given parameter size.

+ // The following functions are based on algorithms from the _Handbook of Applied Cryptography_

+ // eGCD_,inverseMod_() = algorithm 14.61, Binary extended GCD_
+ // GCD_() = algorothm 14.57, Lehmer's algorithm
+ // mont_() = algorithm 14.36, Montgomery multiplication
+ // divide_() = algorithm 14.20 Multiple-precision division
+ // squareMod_() = algorithm 14.16 Multiple-precision squaring
+ // randTruePrime_() = algorithm 4.62, Maurer's algorithm
+ // millerRabin() = algorithm 4.24, Miller-Rabin algorithm
+ //
+ // Profiling shows:
+ // randTruePrime_() spends:
+ // 10% of its time in calls to powMod_()
+ // 85% of its time in calls to millerRabin()
+ // millerRabin() spends:
+ // 99% of its time in calls to powMod_() (always with a base of 2)
+ // powMod_() spends:
+ // 94% of its time in calls to mont_() (almost always with x==y)
+ //
+ // This suggests there are several ways to speed up this library slightly:
+ // - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
+ // -- this should especially focus on being fast when raising 2 to a power mod n
+ // - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test
+ // - tune the parameters in randTruePrime_(), including c, m, and recLimit
+ // - speed up the single loop in mont_() that takes 95% of the runtime, perhaps by reducing checking
+ // within the loop when all the parameters are the same length.
+ //
+ // There are several ideas that look like they wouldn't help much at all:
+ // - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
+ // - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
+ // - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
+ // followed by a Montgomery reduction. The intermediate answer will be twice as long as x, so that
+ // method would be slower. This is unfortunate because the code currently spends almost all of its time
+ // doing mont_(x,x,...), both for randTruePrime_() and powMod_(). A faster method for Montgomery squaring
+ // would have a large impact on the speed of randTruePrime_() and powMod_(). HAC has a couple of poorly-worded
+ // sentences that seem to imply it's faster to do a non-modular square followed by a single
+ // Montgomery reduction, but that's obviously wrong.

+ // Big Integer Library v. 5.5
+ // Created 2000, last modified 2013
+ // Leemon Baird
+ // www.leemon.com
+ //
+ // Version history:
+ // v 5.5 17 Mar 2013
+ // - two lines of a form like "if (x<0) x+=n" had the "if" changed to "while" to
+ // handle the case when x<-n. (Thanks to James Ansell for finding that bug)
+ // v 5.4 3 Oct 2009
+ // - added "var i" to greaterShift() so i is not global. (Thanks to Péter Szabó for finding that bug)
+ //
+ // v 5.3 21 Sep 2009
+ // - added randProbPrime(k) for probable primes
+ // - unrolled loop in mont_ (slightly faster)
+ // - millerRabin now takes a bigInt parameter rather than an int
+ //
+ // v 5.2 15 Sep 2009
+ // - fixed capitalization in call to int2bigInt in randBigInt
+ // (thanks to Emili Evripidou, Reinhold Behringer, and Samuel Macaleese for finding that bug)
+ //
+ // v 5.1 8 Oct 2007
+ // - renamed inverseModInt_ to inverseModInt since it doesn't change its parameters
+ // - added functions GCD and randBigInt, which call GCD_ and randBigInt_
+ // - fixed a bug found by Rob Visser (see comment with his name below)
+ // - improved comments
+ //
+ // This file is public domain. You can use it for any purpose without restriction.
+ // I do not guarantee that it is correct, so use it at your own risk. If you use
+ // it for something interesting, I'd appreciate hearing about it. If you find
+ // any bugs or make any improvements, I'd appreciate hearing about those too.
+ // It would also be nice if my name and URL were left in the comments. But none
+ // of that is required.
+ //
+ // This code defines a bigInt library for arbitrary-precision integers.
+ // A bigInt is an array of integers storing the value in chunks of bpe bits,
+ // little endian (buff[0] is the least significant word).
+ // Negative bigInts are stored two's complement. Almost all the functions treat
+ // bigInts as nonnegative. The few that view them as two's complement say so
+ // in their comments. Some functions assume their parameters have at least one
+ // leading zero element. Functions with an underscore at the end of the name put
+ // their answer into one of the arrays passed in, and have unpredictable behavior
+ // in case of overflow, so the caller must make sure the arrays are big enough to
+ // hold the answer. But the average user should never have to call any of the
+ // underscored functions. Each important underscored function has a wrapper function
+ // of the same name without the underscore that takes care of the details for you.
+ // For each underscored function where a parameter is modified, that same variable
+ // must not be used as another argument too. So, you cannot square x by doing
+ // multMod_(x,x,n). You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
+ // Or simply use the multMod(x,x,n) function without the underscore, where
+ // such issues never arise, because non-underscored functions never change
+ // their parameters; they always allocate new memory for the answer that is returned.
+ //
+ // These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
+ // For most functions, if it needs a BigInt as a local variable it will actually use
+ // a global, and will only allocate to it only when it's not the right size. This ensures
+ // that when a function is called repeatedly with same-sized parameters, it only allocates
+ // memory on the first call.
+ //
+ // Note that for cryptographic purposes, the calls to Math.random() must
+ // be replaced with calls to a better pseudorandom number generator.
+ //
+ // In the following, "bigInt" means a bigInt with at least one leading zero element,
+ // and "integer" means a nonnegative integer less than radix. In some cases, integer
+ // can be negative. Negative bigInts are 2s complement.
+ //
+ // The following functions do not modify their inputs.
+ // Those returning a bigInt, string, or Array will dynamically allocate memory for that value.
+ // Those returning a boolean will return the integer 0 (false) or 1 (true).
+ // Those returning boolean or int will not allocate memory except possibly on the first
+ // time they're called with a given parameter size.

+ // The following functions are based on algorithms from the _Handbook of Applied Cryptography_

+ // eGCD_,inverseMod_() = algorithm 14.61, Binary extended GCD_
+ // GCD_() = algorothm 14.57, Lehmer's algorithm
+ // mont_() = algorithm 14.36, Montgomery multiplication
+ // divide_() = algorithm 14.20 Multiple-precision division
+ // squareMod_() = algorithm 14.16 Multiple-precision squaring
+ // randTruePrime_() = algorithm 4.62, Maurer's algorithm
+ // millerRabin() = algorithm 4.24, Miller-Rabin algorithm
+ //
+ // Profiling shows:
+ // randTruePrime_() spends:
+ // 10% of its time in calls to powMod_()
+ // 85% of its time in calls to millerRabin()
+ // millerRabin() spends:
+ // 99% of its time in calls to powMod_() (always with a base of 2)
+ // powMod_() spends:
+ // 94% of its time in calls to mont_() (almost always with x==y)
+ //
+ // This suggests there are several ways to speed up this library slightly:
+ // - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
+ // -- this should especially focus on being fast when raising 2 to a power mod n
+ // - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test

+ // There are several ideas that look like they wouldn't help much at all:
+ // - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
+ // - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
+ // - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
+ // followed by a Montgomery reduction. The intermediate answer will be twice as long as x, so that
+ // method would be slower. This is unfortunate because the code currently spends almost all of its time
+ // doing mont_(x,x,...), both for randTruePrime_() and powMod_(). A faster method for Montgomery squaring
+ // would have a large impact on the speed of randTruePrime_() and powMod_(). HAC has a couple of poorly-worded
+ // sentences that seem to imply it's faster to do a non-modular square followed by a single
+ // Montgomery reduction, but that's obviously wrong.

+ // Big Integer Library v. 5.5
+ // Created 2000, last modified 2013
+ // Leemon Baird
+ // www.leemon.com
+ //
+ // Version history:
+ // v 5.5 17 Mar 2013
+ // - two lines of a form like "if (x<0) x+=n" had the "if" changed to "while" to
+ // handle the case when x<-n. (Thanks to James Ansell for finding that bug)
+ // v 5.4 3 Oct 2009
+ // - added "var i" to greaterShift() so i is not global. (Thanks to Péter Szabó for finding that bug)
+ //
+ // v 5.3 21 Sep 2009
+ // - added randProbPrime(k) for probable primes
+ // - unrolled loop in mont_ (slightly faster)
+ // - millerRabin now takes a bigInt parameter rather than an int
+ //
+ // v 5.2 15 Sep 2009
+ // - fixed capitalization in call to int2bigInt in randBigInt
+ // (thanks to Emili Evripidou, Reinhold Behringer, and Samuel Macaleese for finding that bug)
+ //
+ // v 5.1 8 Oct 2007
+ // - renamed inverseModInt_ to inverseModInt since it doesn't change its parameters
+ // - added functions GCD and randBigInt, which call GCD_ and randBigInt_
+ // - fixed a bug found by Rob Visser (see comment with his name below)
+ // - improved comments
+ //
+ // This file is public domain. You can use it for any purpose without restriction.
+ // I do not guarantee that it is correct, so use it at your own risk. If you use
+ // it for something interesting, I'd appreciate hearing about it. If you find
+ // any bugs or make any improvements, I'd appreciate hearing about those too.
+ // It would also be nice if my name and URL were left in the comments. But none
+ // of that is required.
+ //
+ // This code defines a bigInt library for arbitrary-precision integers.
+ // A bigInt is an array of integers storing the value in chunks of bpe bits,
+ // little endian (buff[0] is the least significant word).
+ // Negative bigInts are stored two's complement. Almost all the functions treat
+ // bigInts as nonnegative. The few that view them as two's complement say so
+ // in their comments. Some functions assume their parameters have at least one
+ // leading zero element. Functions with an underscore at the end of the name put
+ // their answer into one of the arrays passed in, and have unpredictable behavior
+ // in case of overflow, so the caller must make sure the arrays are big enough to
+ // hold the answer. But the average user should never have to call any of the
+ // underscored functions. Each important underscored function has a wrapper function
+ // of the same name without the underscore that takes care of the details for you.
+ // For each underscored function where a parameter is modified, that same variable
+ // must not be used as another argument too. So, you cannot square x by doing
+ // multMod_(x,x,n). You must use squareMod_(x,n) instead, or do y=dup(x); multMod_(x,y,n).
+ // Or simply use the multMod(x,x,n) function without the underscore, where
+ // such issues never arise, because non-underscored functions never change
+ // their parameters; they always allocate new memory for the answer that is returned.
+ //
+ // These functions are designed to avoid frequent dynamic memory allocation in the inner loop.
+ // For most functions, if it needs a BigInt as a local variable it will actually use
+ // a global, and will only allocate to it only when it's not the right size. This ensures
+ // that when a function is called repeatedly with same-sized parameters, it only allocates
+ // memory on the first call.
+ //
+ // Note that for cryptographic purposes, the calls to Math.random() must
+ // be replaced with calls to a better pseudorandom number generator.
+ //
+ // In the following, "bigInt" means a bigInt with at least one leading zero element,
+ // and "integer" means a nonnegative integer less than radix. In some cases, integer
+ // can be negative. Negative bigInts are 2s complement.
+ //
+ // The following functions do not modify their inputs.
+ // Those returning a bigInt, string, or Array will dynamically allocate memory for that value.
+ // Those returning a boolean will return the integer 0 (false) or 1 (true).
+ // Those returning boolean or int will not allocate memory except possibly on the first
+ // time they're called with a given parameter size.

+ // Profiling shows:
+ // randTruePrime_() spends:
+ // 10% of its time in calls to powMod_()
+ // 85% of its time in calls to millerRabin()
+ // millerRabin() spends:
+ // 99% of its time in calls to powMod_() (always with a base of 2)
+ // powMod_() spends:
+ // 94% of its time in calls to mont_() (almost always with x==y)
+ //
+ // This suggests there are several ways to speed up this library slightly:
+ // - convert powMod_ to use a Montgomery form of k-ary window (or maybe a Montgomery form of sliding window)
+ // -- this should especially focus on being fast when raising 2 to a power mod n
+ // - convert randTruePrime_() to use a minimum r of 1/3 instead of 1/2 with the appropriate change to the test
+ // - tune the parameters in randTruePrime_(), including c, m, and recLimit
+ // - speed up the single loop in mont_() that takes 95% of the runtime, perhaps by reducing checking
+ // within the loop when all the parameters are the same length.
+ //
+ // There are several ideas that look like they wouldn't help much at all:
+ // - replacing trial division in randTruePrime_() with a sieve (that speeds up something taking almost no time anyway)
+ // - increase bpe from 15 to 30 (that would help if we had a 32*32->64 multiplier, but not with JavaScript's 32*32->32)
+ // - speeding up mont_(x,y,n,np) when x==y by doing a non-modular, non-Montgomery square
+ // followed by a Montgomery reduction. The intermediate answer will be twice as long as x, so that
+ // method would be slower. This is unfortunate because the code currently spends almost all of its time
+ // doing mont_(x,x,...), both for randTruePrime_() and powMod_(). A faster method for Montgomery squaring
+ // would have a large impact on the speed of randTruePrime_() and powMod_(). HAC has a couple of poorly-worded
+ // sentences that seem to imply it's faster to do a non-modular square followed by a single
+ // Montgomery reduction, but that's obviously wrong.
