In firefox (and I understand Chrome), the encryption is based on
libsrtp, which includes some FIPS tests in the source. Note however
those test it in isolation, so that's not exactly the same thing as
in-the-browser, and that doesn't cover key exchange/derivation via
DTLS-SRTP, etc.
In firefox, see netwerk/srtp/src/*
