I have used openssl to generate these hashes. Here's the cpu code I use
for debugging. It has both openssl and non-openssl version of pbkdf2 but
their outputs are exactly same. The number of guesses for opencl version
is 1410 even for 27 as plaintext length. So I don't think there are
plaintext longer than 27 chars in TS.
