Using AS2 in NIST 800-131a compliance mode
SHA256, SHA318, and SHA512 signing algorithms are added to AS2 configuration for signing messages and MDN’s to support NIST 800-131a compliance. When configuring an AS2 trading partner, or organization profiles, only NIST 800-131a compliant certificates/algorithms are available for use. If you receive an error, you must go back to the configuration page and re-configure for NIST 800-131a compliance.
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 AS2 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.
