About Hash Functions
A hash function takes an input (or 'message') and returns a fixed-size string of bytes. The output is typically a 'digest' that is unique to each unique input.
Common hash algorithms:
- MD5: 128-bit hash value. Fast but considered cryptographically broken.
- SHA1: 160-bit hash value. More secure than MD5 but also considered insecure.
- SHA256: 256-bit hash value. Part of the SHA-2 family, widely used and secure.
- SHA512: 512-bit hash value. Stronger than SHA256 but produces larger hashes.
Common uses of hashing:
- Data integrity verification
- Password storage (with salt)
- Digital signatures
- Blockchain technology
Security Note: For password storage, always use a slow hashing algorithm like bcrypt, scrypt, or Argon2 with a unique salt for each password.
