Description Simo Sorce 2019-05-06 13:59:57 UTC

FIPS requires continuous tests of the input to the libraries CSPRNG but the kernel getrandom() (or /dev[u]random) interface does not do it.

Available options is to implement tests in the library or use the kernel AF_ALG DRBG source which wil have these tests implemented in kernel.

Comment 1 Tomas Mraz 2019-05-06 14:03:32 UTC

This should be applied in the FIPS mode.
