Actually, there's a RFC:  
  http://www.ietf.org/rfc/rfc3778.txt  

- adbe.x509.rsa_sha1 (PKCS#11)
- adbe.pkcs7.sha1
- adbe.pkcs7.detached

P.S.  Digital signatures here guys, _not_ encryption.
Just FYI in case you were going to post "security in
PDF sucks" regarding its ROT13 encryption.  And yes,
I know about SHA-1, but it's FIPS 140/180.
