Subject: Add support for HMAC-SHA-256 as an SSH-2 MAC algorithm ("hmac-sha2-256")
X-Git-Url: https://git.distorted.org.uk/u/mdw/putty/commitdiff_plain/23159902a3ae593f9022578201125600a8da8de1?hp=23159902a3ae593f9022578201125600a8da8de1

Add support for HMAC-SHA-256 as an SSH-2 MAC algorithm ("hmac-sha2-256")
as specified in RFC 6668.  This is not so much because I think it's
necessary, but because scrypt uses HMAC-SHA-256 and once we've got it we
may as well use it.

Code very closely derived from the HMAC-SHA-1 code.

Tested against OpenSSH 5.9p1 Debian-5ubuntu1.
