[RFC PATCH 3/8] crypto/krb5: Test manager data

David Howells
2025-01-10T01:03:48Z

Add Kerberos crypto tests to the test manager database. This covers:

camellia128-cts-cmac samples from RFC6803
camellia256-cts-cmac samples from RFC6803
aes128-cts-hmac-sha256-128 samples from RFC8009
aes256-cts-hmac-sha384-192 samples from RFC8009

but not:

aes128-cts-hmac-sha1-96
aes256-cts-hmac-sha1-96

as the test samples in RFC3962 don't seem to be suitable.

Note that the test manager makes some assumptions about AEAD algorithm type
that would otherwise prevent testing the kerberos algorithms. The problem
is that the test manager assumes that if there's a difference between the
length of the plain text and the cipher text supplied in the test vector,
then the extra data is the authentication tag - but these aren't applicable
here.

This is worked around by adding a flag in the AEAD algorithm definition
that causes EINVAL be returned unconditionally if anyone tries to set the
auth tag length.
