About Hash Functions
What are hash functions: Hash functions are mathematical algorithms that convert data of any size into a fixed-size output (hash value). They are designed to be one-way functions, meaning it should be computationally infeasible to reverse the process.
Common uses: Password storage, data integrity verification, digital signatures, and file checksums.
Security Considerations
- SHA-1: No longer considered secure for cryptographic purposes.
- SHA-256 and above: Currently considered secure for most applications.
- Password hashing: For storing passwords, specialized algorithms like bcrypt, Argon2, or PBKDF2 are recommended instead of simple hash functions.
- Client-side computation: This tool performs all hash calculations in your browser using the Web Crypto API, so your data never leaves your computer.
