[IPP] 5100.11 "job-password-encryption-supported" - what SHA version does 'sha' keyword indicate? Michael Sweet msweet at apple.com Mon Jun 16 20:56:01 UTC 2014 OK, the consensus at today's concall is that "sha" refers to SHA-1. We will register the following values for SHA2: sha2-224 sha2-256 sha2-384 sha2-512 sha2-512_256 The latter is the 512-bit SHA-2 hash truncated to 256 bits as used in the upcoming HTTP Digest authentication update. Once a non-draft US NIST (or other) specification is released, we will also register the following new values for SHA-3 and Shake: sha3-224 sha3-256 sha3-384 sha3-512 sha3-512_256 shake-128 shake-256 The IANA registration information for the SHA-2 registrations is: Attributes (attribute syntax) Keyword Attribute Value Reference ----------------------- --------- job-password-encryption (type2 keyword) [PWG5100.11] sha2-224 sha2-256 sha2-384 sha2-512 sha2-512_256 On Jun 12, 2014, at 4:52 PM, Kennedy, Smith (Wireless Architect) wrote: > Greetings, > > PWG 5100.11 (JPS2) defines the “job-password-encryption-supported” attribute. > One of the keywords defined in JPS2 is ’sha’.
