What's the command line to generate a blowfish password hash? I can't seem to figure this out at all. Apache's htpasswd only supports bcrypt, and openssl passwd doesn't even do blowfish hahes (but it does do blowfish encryptions with openssl enc).
Most sites point me to using $2a$ which is bcrypt, not blowfish ($2y$). Also a lot of places seem to confuse blowfish password hashing with blowfish file encryption. There are a lot of online sites which will generate blowfish hash for you, but I don't want to use an untrusted third party.
What other secure linux tools can I use to generate a blowfish password hash? I want to be able to define the two digit cost parameter as well as the salt.
