https://tools.ietf.org/html/rfc3370 section 2 specifies that the NULL parameters field is mandatory for some algorithms, optional for some others. For compatibility reasons we have always added it. I do note that RFC 5754 section says that implementations MUST leave out the NULL for SHA-2 except where it is used in PKCS#1... it does say both should be accepted, but we need to look into this further. The patch proposed is not enough but it does appear something should be changed. |
