[CRYPTO] tcrypt: Add self test for des3_ebe cipher operating in cbc mode
Patch to add checking of DES3 test vectors using CBC mode. FIPS-140-2 compliance mandates that any supported mode of operation must include a self test. This satisfies that requirement for cbc(des3_ede). The included test vector was generated by me using openssl. Key/IV was generated with the following command: openssl enc -des_ede_cbc -P input and output values were generated by repeating the string "Too many secrets" a few times over, truncating it to 128 bytes, and encrypting it with openssl using the aformentioned key. Tested successfully by myself Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Adrian-Ken Rueegsegger <rueegsegger@swiss-it.ch> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
