Comment 3 for bug 1629370

Sorry, I was referring to PKCS#1 v2.2

See https://www.emc.com/collateral/white-papers/h11300-pkcs-1v2-2-rsa-cryptography-standard-wp.pdf

Page 49, B.1

Exception: When formatting the DigestInfoValue in EMSA-PKCS1-v1_5 (see 9.2), the
parameters field associated with id-sha1, id-sha512/224, id-sha224, id-sha256, id-sha384,
id-sha512, and id-sha512/256 shall have a value of type NULL. This is to maintain
compatibility with existing implementations and with the numeric information values
already published for EMSA-PKCS1-v1_5 which are also reflected in IEEE 1363a-2004
[26].
