yes ssha-opencl is setted to have password up to 15 chars; this due to
to speed issue on opencl; however you can switch plaintext_length to
32 and there shouldn't be problem .

one question; on a general side, what is the perfect PLAINTEXT_LENGTH
value ? 32 is it good enough ?

p.s.
i've been playing a bit with the testsuite and it rocks; sooner
i'll try to take some time to fix md5-opencl and NT opencl.

Cheers
Samuele
