About Hash Functions
A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a fixed-size hash value. Hash functions are one-way functions that are designed to be practically impossible to reverse.
Common Uses
- Password storage and verification
- Data integrity verification
- Digital signatures
- File checksums
- Blockchain and cryptocurrencies
Security Considerations
- MD5: Deprecated due to collision vulnerabilities. Do not use for security purposes.
- SHA-1: Deprecated. Vulnerable to collision attacks.
- SHA-256/384/512: Currently considered secure for most applications.
