--------------------------------------
Type: Technical
Reported by: Jos Breek <jos(_dot_)breek(_at_)ul(_dot_)com>
Section: 5.3
Original Text
-------------
digestAlgorithm identifies the message digest algorithm, and any
associated parameters, used by the signer.
Corrected Text
--------------
digestAlgorithm identifies the message digest algorithm, and any
associated parameters, used by the signer in the signature Generation
Process. The message digest algorithm shall be equal to the message
digest algorithm used in the signatureAlgorithm field.
Notes
-----
The text stated that the message digest algorithm is "used by the signer". It
is unclear for what purpose the message digest algorithm is used.
There are implementations that use the message digest algorithm specified in
the messageDigest field instead of the message digest algorithm specified in
the signatureAlgorithm.
Is the purpose of the messageDigest field to nest the hashing algorithm used in
the signing process? If so, please use the corrected text to clarify the goal
of the field.
Instructions:
-------------
This errata is currently posted as "Reported". If necessary, please
