patch solving 'Unknowk hash algorithm' output message

Description of problem:
rpm doesn't understand sha224, but is possible sign it with sha224 algorithm.

Version-Release number of selected component (if applicable):
rpm-4.8.0-9.el6

How reproducible:
always

Steps to Reproduce:
1. modify ".gnupg/gpg.conf" to have as first default value H11 (SHA224) in 'personal-digest-preferences' and 'default-preference-list' variables, or in "~/.rpmmacros" change %__gpg_sign_cmd to %{__gpg} --digest-algo sha224 --batch --no-verbose --no-armor --passphrase-fd 3 --no-secmem-warning -u "%{_gpg_name}" -sbo %{__signature_filename} %{__plaintext_filename}
2. run "rpm -addsign some.rpm"
3. run "rpm -v --checksig some.rpm"
  
Actual results:
rpm -v --checksig mod_gnutls-0.5.6-1.md5.x86_64.rpm
mod_gnutls-0.5.6-1.md5.x86_64.rpm:
    Header V3 RSA/Unknown hash algorithm Signature, key ID c842f47e: BAD
    Header SHA1 digest: OK (2a30e68848f8aa15028e160164ce309c26b6f735)
    V3 RSA/MD5 Signature, key ID 40e6c3a4: OK
    V3 RSA/Unknown hash algorithm Signature, key ID c842f47e: BAD
    MD5 digest: OK (7b86a7c836b21679133b77ff7cdce95b)


Expected results:
rpm -v --checksig mod_gnutls-0.5.6-1.md5.x86_64.rpm
mod_gnutls-0.5.6-1.md5.x86_64.rpm:
    Header V3 RSA/SHA224 Signature, key ID c842f47e: OK
    Header SHA1 digest: OK (2a30e68848f8aa15028e160164ce309c26b6f735)
    V3 RSA/MD5 Signature, key ID 40e6c3a4: OK
    V3 RSA/SHA224 Signature, key ID c842f47e: OK
    MD5 digest: OK (7b86a7c836b21679133b77ff7cdce95b)

patch, which should be used, when nss will support SHA224

HASH_AlgSHA224 must be provided by nss, unless this patch is useless
Comment 3 Panu Matilainen 2010-06-29 03:51:51 EDT
Ack for the first patch (applied upstream, thanks) and also for verifying the generated signature is something rpm's implementation (ie NSS) supports (some basic sanity tests added upstream now).
