[PATCH] Allow SHA2 hash functions on gnupg 2 with scdaemon

[Diego Elio Pettenò]

Hi,

I'm attaching a patch that implement support for the SHA2 hash functions
in GnuPG 2 when using scdaemon.

A similar issue was reported and fixed (although in a different, IMHO
less optimal, way) in early 2010 [1] but the same issue held true for
GnuPG 2.

Without this patch, if ~/.gnupg/gpg.conf contains these lines:

  personal-digest-preferences SHA256
  cert-digest-algo SHA256
  default-preference-list SHA512 SHA384 SHA256 SHA224 AES256 AES192 AES
CAST5 ZLIB BZIP2 ZIP Uncompressed

then a sign action would report this:

  gpg: checking created signature failed: Bad signature
  gpg: signing failed: Bad signature
  gpg: [stdin]: clearsign failed: Bad signature

after applying the patch.. well, this email is signed, I hope :)

As it is, it applies fine over 2.0.16 and svn branch.

HTH,
