1059926 - Expand DottedOidToCode.py's output options

Status: RESOLVED FIXED

(Core :: Security: PSM, defect)

Description

[Brian Smith (:briansmith, :bsmith, use NEEDINFO?)]

Attachment: dotted-oid-improvement.patch

This patch expands DottedOidToCode.py by giving it two optional and mutually-exclusive options, "--tlv" and "--alg". Without either option, DottedOidToCode.py continues to output just the encoded OID value, without the tag and length. With "--tlv", the tag and length are prepended to the output. With "--alg", the output of "--tlv" is wrapped in a SEQUENCE so that it becomes a valid AlgorithmIdentifier.

This expanded functionality is used in an upcoming patch; when I file that bug, I will add the bug dependency.
