class Crypto::Bcrypt::Password
Overview
Generate, read and verify Crypto::Bcrypt hashes.
password = Crypto::Bcrypt::Password.create("super secret", cost: 10)
# => $2a$10$rI4xRiuAN2fyiKwynO6PPuorfuoM4L2PVv6hlnVJEmNLjqcibAfHq
password == "wrong secret" # => false
password == "super secret" # => trueSee Crypto::Bcrypt for hints to select the cost when generating hashes.
