2025-03-02crypto/krb5: Implement crypto self-testingDavid Howells
Implement self-testing infrastructure to test the pseudo-random function, key derivation, encryption and checksumming. Add the testing data from rfc8009 to test AES + HMAC-SHA2. Add the testing data from rfc6803 to test Camellia. Note some encryption test vectors here are incomplete, lacking the key usage number needed to derive Ke and Ki, and there are errata for this: https://www.rfc-editor.org/errata_search.php?rfc=6803 Signed-off-by: David Howells <dhowells@redhat.com> cc: Herbert Xu <herbert@gondor.apana.org.au> cc: "David S.

2025-03-02crypto/krb5: Implement the Camellia enctypes from rfc6803David Howells
Implement the camellia128-cts-cmac and camellia256-cts-cmac enctypes from rfc6803. Note that the test vectors in rfc6803 for encryption are incomplete, lacking the key usage number needed to derive Ke and Ki, and there are errata for this: https://www.rfc-editor.org/errata_search.php?rfc=6803 Signed-off-by: David Howells <dhowells@redhat.com> cc: Herbert Xu <herbert@gondor.apana.org.au> cc: "David S.
