[1] The Time Stamping [2] Policy Server used in conjunction with the Digi-CA™ [3]:

• accepts client requests in format accepted by this standard
• accepts all request parameters enforced by this standard
• recognizes and supports the following hashing algorithms: SHA-1, MD5, RIPEMD-160
• supports signature algorithm: SHA1 with RSA
• supports key length: 1024-2048
• supports Time Stamp Protocol via HTTP

And in so doing makes Digi-CA™ compliant with this standard.
