[Pkg-openssl-devel] Bug#554157: OpenSSL x509 Cert with UTF-8 Email Address

[Scott Schaefer]

AFAICT, this is correct.

IETF RFC 5280 declares the EMailAddress attrribute to be of type IA5TRING

EmailAddress ::=     IA5String (SIZE (1..ub-emailaddress-length))

It further notes ...
The attribute value for emailAddress is of type IA5String to permit
inclusion of the character '@', which is not part of the
PrintableString character set.

See http://tools.ietf.org/html/rfc5280

The IA5 character set only includes values 0..127.
