Using AS1 in NIST 800-131a compliance mode

SHA256 signing algorithm was added to AS1 configuration to support NIST 800-131a compliance. When configuring an AS1 trading partner, only NIST 800-131a compliant certificates are used.

If a certificate with non-NIST 800-131a compliance exists in the system prior to upgrading to NIST 800-131a mode, the following message appears, Not NIST SP800-131a compliant. You must create a new NIST 800-131a compliant certificate and re-configure AS1 to use the new certificate.

If a non-NIST 800-131a compliance certificate, signature, or algorithm is used, the business process will fail, indicating in the status report that the certificate is Not NIST SP800-131a compliant.
