Sure, reposting 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.
