Cryptographic hash functions convert input data of any size into a fixed-size string of characters. They are one-way functions, meaning you cannot reverse the process to get the original input.
Supported Algorithms
- MD5 - 128-bit hash. Fast but deprecated for security purposes. Use only for non-security checksums.
- SHA-1 - 160-bit hash. Deprecated for security. Still used in some legacy systems.
- SHA-256 - 256-bit hash from SHA-2 family. Strong and widely used for security applications.
- SHA-512 - 512-bit hash from SHA-2 family. Very strong and recommended for maximum security.
Common Use Cases
- File Integrity - Verify downloads haven't been corrupted
- Password Storage - Store hashed passwords (with salt)
- Data Deduplication - Identify duplicate files
- Digital Signatures - Verify data authenticity
- Git Commits - Git uses SHA-1 for commit hashes
- Blockchain - Bitcoin uses SHA-256
Security Notes
⚠️ Important: MD5 and SHA-1 are cryptographically broken and should not be used for security purposes. Use SHA-256 or SHA-512 for any security-related applications. Never use plain hashing for passwords - always use proper password hashing algorithms like bcrypt, Argon2, or PBKDF2.
