All-in-One Hash Calculator
Compute MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, and other hash values for any text string or file you upload. All algorithms run side-by-side, so you can compare the same input across multiple hash functions at once.
Common Use Cases
Use the Hash Calculator (MD5, SHA-256, etc.) online for these scenarios:
- Password verification: Understand how websites hash passwords (production uses bcrypt/Argon2)
- File integrity check: Compare SHA256 hash of downloaded files to ensure they are not tampered with
- Git commit verification: View SHA1 hashes of Git commits
- API signatures: Understand HMAC, API key signing using hash algorithms
- Data deduplication: Hash large files to quickly compare content equality
Frequently Asked Questions
Here are the most common questions:
Q: Is MD5 still secure?
A: No. MD5 has been broken and collisions can be constructed. Only use for integrity checks, never for security.
Q: SHA256 vs SHA512 — which to choose?
A: Use SHA256 generally. SHA512 may be slightly faster on 64-bit systems with longer output. Both are equally secure.
Q: Why not use MD5 for passwords?
A: MD5 is too fast, vulnerable to rainbow tables. Use bcrypt/Argon2/scrypt for password storage.
