	OID_sha1,			/* 1.3.14.3.2.26 */
	OID_sha256,			/* 2.16.840.1.101.3.4.2.1 */

I suspect I'm missing something here in oid_registry.h.  Looking online, I
see:

	id-sha256 OBJECT IDENTIFIER ::= { hashAlgs 1 }
	id-sha384 OBJECT IDENTIFIER ::= { hashAlgs 2 }
	id-sha512 OBJECT IDENTIFIER ::= { hashAlgs 3 }
	id-sha224 OBJECT IDENTIFIER ::= { hashAlgs 4 }
	id-sha512-224 OBJECT IDENTIFIER ::= { hashAlgs 5 }
	id-sha512-256 OBJECT IDENTIFIER ::= { hashAlgs 6 }

Are you perchance using sha512 hashes in your signatures?
