Bcrypt.js
bcrypt.js is a portable JavaScript implementation of the bcrypt algorithm used for securely hashing and verifying user passwords. It functions as a credential security utility that protects stored passwords against brute-force attacks through the use of salts and configurable work factors.
The library is designed as a pure JavaScript cryptographic module, allowing it to run in any JavaScript environment, including both server-side Node.js and client-side web browsers, without requiring native system binaries or C++ bindings. It is a zero-dependency standalone module to minimize security risks and installation overhead.
Its core capabilities cover the transformation of plain-text passwords into secure hashes and the verification of those hashes during authentication workflows. The project includes tools for salt generation, password truncation detection, and the extraction of salt strings and iteration counts from encrypted hashes.
