Detailed Description

Known-answer tests of the hardware accelerators.

Feeds the FIPS 180-4 and FIPS 197 examples through the hardware hooks (see Crypto). An algorithm that fails stays in software from then on. Built with CONFIG_CRYPTO_SELFTEST, which also checks each algorithm before its first hardware use.

Enumeration Type Documentation

pbl_crypto_alg

enum pbl_crypto_alg

Algorithm.

Enumerator
PBL_CRYPTO_ALG_SHA256	SHA-256.
PBL_CRYPTO_ALG_AES	AES, every key size, both ways.

Function Documentation

pbl_crypto_selftest()

int pbl_crypto_selftest

(

enum pbl_crypto_alg

alg

)

Check the accelerator of an algorithm.

Parameters

alg	Algorithm.

Return values

0	if the accelerator returned the expected results.
-ENODEV	if there is no accelerator for alg, or it is not ready.
-EIO	if it returned a wrong result; the algorithm stays in software from then on.
