In my
application (a variant on onion routing) I know that my data comes in
16-byte blocks, so there's no need for padding. Since I'm repeatedly
encrypting data, it's very difficult to use PKCS padding, as that
increases the length of the data at each encryption.
How can I
turn off padding? The online docs say that EVP_CIPHER_CTX_set_padding()
should work, but as far as I can tell, that function is not in the
current distribution (0.9.6d). Am I (and my compiler) missing the
definition somewhere? Is there another way to do desede3_cbc unpadded
with EVP?
Thanks,
Bob
