RE: [pkcs11] Groups - Add descriptions for ECDSA SHA2 and SHA3 mechanism

Bob, all,

Last mail from myself for today…

In my opinion, the proposal is a bit chatty. Is it necessary to describe all 9 SHA mechanisms in separate sections although the text is always the same – except for the name of the mechanism? The current standard is not consistent here: For example, PKCS #1 RSA PSS signatures (sect. 2.1.17) does it in one section, DSA (sect. 2.2.12, 2.2.14 – 2.2.17) uses several sections.

So, similar to PKCS #1 RSA PSS, the following could be added to the “ECDSA with SHA-1” section (which needs to be renamed then) after the first paragraph:

“The ECDSA with SHA-224, SHA-256, SHA-384, SHA-512, SHA3-224, SHA3-256, SHA3-384, and SHA3-512 mechanisms denoted CKM_ECDSA_SHA224, CKM_ECDSA_SHA256, CKM_ECDSA_SHA384, CKM_ECDSA_SHA512, CKM_ECDSA_SHA3_224, CKM_ECDSA_SHA3_256, CKM_ECDSA_SHA3_384, and CKM_ECDSA_SHA3_512 respectively, perform the same operations using the SHA-224, SHA-256, SHA-384, SHA-512, SHA3-224, SHA3-256, SHA3-384, and SHA3-512 hash functions.”

And all other new sections are obsolete.

Best regards,

Daniel

Submitter's message
Here's the text to resolve issue #16.
-- Mr. Robert Relyea

Document Name: Add descriptions for ECDSA SHA2 and SHA3 mechanisms.

Description
Issue #16

Definitions of CKM_ECDSA_SHA224, CKM_ECDSA_SHA256, CKM_ECDSA_SHA384 and
CKM_ECDSA_SHA512 are completely new in v2.40e1 headers.
They were not present in any older version and currently are not described
in the docs.
This may be a leftover from v2.30 headers (see #2).

This is still an issue.
Option 1: remove CKM_ECDSA_SHA224, CKM_ECDSA_SHA256, CKM_ECDSA_SHA384 and
CKM_ECDSA_SHA512 from the header.
Option 2: Add definitions in the document for these mechanism.
Option 3: Option 2 plus add definitions for the SHA3 equivalents.
Recommendation: Option 3
