Looking at the keys defined in testmgr.h for DES3, it looks like there is a real parity issue with the test vectors. A DES key is supposed to have all bytes with an odd number of ones. It is not the case in the key below. At least the second byte 0xC0 has an even number of ones. static struct cipher_testvec des3_ede_cbc_enc_tv_template[] = { { /* Generated from openssl */ .key = "\xE9\xC0\xFF\x2E\x76\x0B\x64\x24" "\x44\x4D\x99\x5A\x12\xD6\x40\xC0" "\xEA\xC2\x84\xE8\x14\x95\xDB\xE8", So, how can this test vector work ?I'm not going to comment on the validity of the test key vector other than to say that you can turn off key parity errors in the SEC1 in the DEU Interrupt Control Register.
