What are Hashes?
Hashes are mathematical functions that convert data of any size into a fixed-size string. They are widely used in security, integrity verification and cryptography.
Hash Algorithm Comparison
| Algorithm | Size | Speed | Security | Recommended Use |
|---|---|---|---|---|
| MD5 | 128 bits (32 chars) | Very Fast | Vulnerable | Simple checksums |
| SHA1 | 160 bits (40 chars) | Fast | Legacy | Legacy systems |
| SHA256 | 256 bits (64 chars) | Moderate | Secure | Modern applications |
| SHA512 | 512 bits (128 chars) | Moderate | Very Secure | Maximum security |
