One basically has to patch a valid private key and clear the least
significant bit of p or q.
With lsh, sexp-conv -s hex should convert an unencrypted private key
into a form suitable for editing in a text editor. After editing,
convert back to canonical (binary) syntax, again using sexp-conv.
For key files as used with gnutls, Hannu suggested using
Niels Möller. PGP-encrypted email is preferred. Keyid C0B98E26.
Internet email is subject to wholesale government surveillance.
