Functions

create_ctx()
Create a context which hashes passwords in a separate thread.
gen_salt(LogRounds)
Generate a random text salt for use with hashpw/3. LogRounds defines the complexity of the hashing, increasing the cost as 2^log_rounds.
hashpw(Ctx, Ref, Pid, Password, Salt)
Hash the specified password and the salt using the OpenBSD Blowfish password hashing algorithm. Returns the hashed password.
