Hi Mariano,
I've made a FFI library on Squeaksource that works on Linux.
http://www.squeaksource.com/Cryptography/PasswordHashingFFI-PaulDeBruicker.8.mcz
You need to install the 32 bit versions of libcrypt and libxcrypt if
you're using a 64 bit linux os.
Using crypt can hash passwords using MD5, DES, SHA256, SHA512.
Using libxcrypt can hash passwords using bcrypt.
If its for a new installation use bcrypt or SHA512 to hash the
passwords. bcrypt is better because its slower, and allegedly future
proof.
to get a hashed password use
BCryptLinuxFFI bcrypt:'mypassword'
to check it against a stored hash use:
BCryptLinuxFFI check:'mypassword' against: storedHash
