This doesn't make sense - or it might not be a complete description of
what you're doing.
Blowfish is a block cipher. It encrypts data with a key, allowing for
quick decryption given the key. In your case, is "hello" the data to
encrypt (with what key?) or the key you're encrypting some other data
with (what data?), or is it both the data and the key?
What are you doing this for?
Most likely, Blowfish - or any other fast cipher, for that matter - is
not appropriate for your task. Instead, you might need to use a
higher-level algorithm specifically intended for password hashing.
The Blowfish-based password hashing method (known as bcrypt) that JtR
supports has very different properties from Blowfish itself. You can
find a description of this hashing method in the paper linked from:
