crypto-js is a JavaScript cryptography library providing a collection of standard cryptographic algorithms and data transformation tools. It functions as a symmetric encryption toolset, a cryptographic hash implementation, and a password derivation tool for the JavaScript environment. The library enables the protection of sensitive data through symmetric encryption and the production of fixed-size data digests to verify integrity. It includes utilities for converting user passwords into secure cryptographic keys and a data format converter for translating information between Base64, Hex, and

This is a Node.js library for securely hashing and verifying passwords using the bcrypt adaptive hashing algorithm. It functions as a password security module that transforms plain-text credentials into protected hashes and generates cryptographically secure salts. The implementation allows for the adjustment of computational cost to resist brute-force attacks. It provides utilities for password hash verification and the extraction of hash metadata to determine the number of encryption rounds used. The project covers a range of security and access control capabilities, including credential s

sjcl is a JavaScript cryptography library providing a collection of primitives for encryption, hashing, and encoding within a web browser. It functions as an AES symmetric encryption tool, a cryptographic hashing library, and a Base32 data encoder. The project provides implementations for the Advanced Encryption Standard to secure data through symmetric key encryption and decryption. It also enables the generation of fixed-length data fingerprints to verify information integrity and authenticity. The library covers a broader range of security capabilities, including client-side data hashing,

jsencrypt is a JavaScript library for performing RSA encryption, decryption, and key generation. It functions as an asymmetric key generator and digital signature provider that executes all cryptographic processing directly in the browser. The library focuses on the use of the PEM standard for importing, exporting, and managing cryptographic keys. It provides the ability to create public and private RSA key pairs of various bit sizes and supports OpenSSL compatible formats. Its capabilities cover the transformation of plaintext into ciphertext and the recovery of original messages using corr

Closure Library is a JavaScript standard library and utility toolset designed for building large-scale web applications. It provides a collection of core utility modules and standardized APIs to simplify complex application logic and state management. The project is built as a modular framework using a namespace-based module system to prevent global scope pollution. It is specifically designed for use with the Closure Compiler to enable aggressive dead-code elimination and minification, reducing the final delivery size in production. To ensure reliability in large projects, the library utiliz
