Removing the src==dst check solves the freeze problem, but the encryption/decryption results are wrong: Encryption: Should be: 69c4e0d86a7b0430d8cdb78070b4c55a But is: c8a331ff8edd3db175e1545dbefb760b Decryption: Should be: 00112233445566778899aabbccddeeff But is: 69c4e0d86a7b0430d8cdb78070b4c55a (same as input) Regards, Martin - To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
