About Hash Functions
Hash functions convert data of any size into a fixed-size string of characters. They're one-way functions, meaning you cannot reverse the hash to get the original data.
Common Uses:
- Password Storage: Store hashed passwords instead of plain text
- File Integrity: Verify files haven't been modified
- Digital Signatures: Authenticate documents and messages
- Data Deduplication: Identify duplicate content
Security Note: MD5 and SHA-1 are not recommended for security-critical applications. Use SHA-256 or higher for password hashing and digital signatures.
Recommendations:
- For Passwords: Use bcrypt, scrypt, or Argon2 (not raw SHA)
- For File Verification: SHA-256 or SHA-512
- For Checksums: MD5 is acceptable (not security-critical)
