Hi Paul,

Sorry for the cross posting.

I was using the Smalltalk version of the Blowfish you did to encrypt and
decrypt things. But now I realize it is very very slow for the usage I
need. You seem to have faced the same problem.

I am encrypting pieces of 8 characters long. But I wonder if the
*decryption* is available as well in FFI version? I see #ffiCrypt:with:
but nothing to decrypt...

Thanks in advance
