About Hash Functions
What is a Hash Function?
A hash function is a mathematical function that converts an input of any size into a fixed-size string of characters, which typically represents a fingerprint of the input data.
Supported Algorithms
- MD5: 128-bit hash, commonly used but cryptographically broken
- SHA-1: 160-bit hash, widely used but cryptographically broken
- SHA-256: 256-bit hash, part of SHA-2 family, cryptographically secure
- SHA-384: 384-bit hash, part of SHA-2 family, cryptographically secure
- SHA-512: 512-bit hash, part of SHA-2 family, cryptographically secure
- RIPEMD-160: 160-bit hash, alternative to SHA-1
- Whirlpool: 512-bit hash, based on AES
- Tiger-192: 192-bit hash, designed for speed
Common Use Cases
- Password storage and verification
- Digital signatures
- File integrity checking
- Message authentication
- Data deduplication
- Blockchain transactions
Best Practices
- Use cryptographically secure hash functions for security
- Add salt to passwords before hashing
- Use appropriate key stretching for password hashing
- Keep hash functions up to date
- Consider collision resistance requirements
- Use multiple rounds for sensitive data
- Store hash outputs securely
