Hi all,

I use cryptlib version 3.4.2 to generate XYZZY certificates for use in AS2.
I use various techniques to meet specific requirements. For example, I can
override CRYPT_CERTINFO_VALIDTO by deleting it and resetting it. Or I can
specify CRYPT_CTXINFO_KEYSIZE in the context with which I sign the cert.

But is there a way to generate an XYZZY certificate with a signature
algorithm of sha256RSA and a signature hash algorithm of sha256? I haven't
found a way so far; all I ever get is sha1RSA and sha1.

Please advise, WAH

P.S. If this is not possible via XYZZY, what would be the simplest approach
to this problem at a lower level in cryptlib?
