[PATCH] crypto: testmgr - allow authenc(hmac(sha{256,384}),cts(cbc(aes))) in FIPS mode
From: Ilya Dryomov
Date: Wed Jun 03 2026 - 12:03:39 EST
hmac(sha256), hmac(sha384) and cts(cbc(aes)) algorithms have been
marked as FIPS allowed for years. Mark the respective authenc()
constructions per RFC 8009 ("AES Encryption with HMAC-SHA2 for
Kerberos 5") as such as well.
SP 800-57 Part 3 Rev. 1 from Jan 2015 [1] links the draft of what
became RFC 8009 in Oct 2016 as approved in section 6.3 Procurement
Guidance (item/recommendation 3).
