crypto: warn on invalid authentication tag length #17566

tniessen · 2017-12-09T13:19:11Z

From NIST SP 800-38d, page 9:

The bit length of the tag, denoted t, is a security parameter [...]. In general, t may be any one of the following five values: 128, 120, 112, 104, or 96. For certain applications, t may be 64 or 32 [...].

An implementation shall not support values for t that are different from the seven choices in the preceding paragraph. An implementation may restrict its support to as few as one of these values.

Ultimately, we should throw an error in this case, but as that is a semver-major change (as explained in #17523 (comment)), this PR logs a warning. If we decide to land this, I will open a separate PR with the semver-major change.

Superfluous, always true because of the cipher->IsAuthenticatedMode() check above.

If we ever add support for other authenticated modes, IsAuthenticatedMode will be true even if the cipher mode is not GCM, and other modes might have different restrictions on the tag size. I can remove the check if you would like.

We'd audit all IsAuthenticatedMode() call sites anyway in that case so that's not a problem.

FIPS mode caused a createCipher warning not to be emitted, should be fixed now.
