bcrypt-ruby is a Ruby binding to the OpenBSD bcrypt() password hashing algorithm, provided as a gem with a native C extension. It lets developers securely hash and verify user passwords, and powers Rails' has_secure_password.

Use cases

• hash user passwords securely in a Ruby app
• verify passwords against bcrypt hashes
• implement authentication in Rails with has_secure_password
• store salted password hashes instead of plaintext
• configure bcrypt cost factor for slower hashing

When to choose

• you need battle-tested password hashing in Ruby or Rails
• you want a simple API for creating and checking bcrypt hashes
• you need cross-platform support including JRuby and Windows

When to avoid

• you need modern memory-hard hashing like Argon2id
• you are not working in Ruby
• you need general-purpose encryption rather than password hashing
