I am putting together a patch using the test vectors found at [3] and the ones I gathered from ANSI X9.52 and ISO/IEC FDIS 10116:2005. Strange enough the ANSI and ISO test vectors pass while the ones from NIST do not yield the expected results. I have not yet identified the specific differences between the various test vector sets. It is not clearly stated if/which padding was employed so that might be the reason... > For future reference, do you have a link where NIST standard test vectors can > be > obtained? A good place to start is [1]. More specifically for TDES: [2] and [3]. Note that the tests described in [2] will not work with the current DES3 implementation since the employed keys will be identified as weak keys and the setkey operation would fail. By the way: when explicitly trying to set a weak key for DES3 I got the following warning: setkey() failed flags=0 Shouldn't the flags be set to CRYPTO_TFM_RES_BAD_KEY_SCHED at that point (see crypto/des_generic.c, line 873)?
