MD5 / SHA Hash Generator
Compute MD5, SHA-1, SHA-256, and SHA-512 hashes for any text string or file you upload. All computation runs locally in your browser using the Web Crypto API — your data never leaves your device.
MD5 / SHA Hash Calculator — Text and File Hashing
ToolOverview
A hash function maps data of any length to a fixed-size fingerprint. Hashes are used for file integrity checks, password storage (with salt), digital signatures, deduplication, and content addressing. This tool supports MD5, SHA-1, SHA-256, and SHA-512. All computation runs locally in your browser — nothing is uploaded.
How to use
- Choose algorithm: MD5 / SHA-1 / SHA-256 / SHA-512
- Enter text or drag in a file
- The hash appears below; click to copy
Use Cases
- Verify a downloaded file matches the official checksum
- Understand Git's commit hash model
- Hashing passwords (but use bcrypt/argon2, not raw MD5)
- Quick content fingerprinting for deduplication
FAQ
Q: Is MD5 insecure?
A: For passwords yes (rainbow tables). For file integrity, cache keys, and fingerprints it is still fine. For security use SHA-256+.
Q: SHA-1 vs SHA-256?
A: Performance is similar. Default to SHA-256 (or SHA-3) for security.
Q: File vs text hash?
A: Same algorithm; large input. SHA-256 produces 64 hex chars.
Tips & Related Tools
For multi-GB files use sha256sum on the command line — browser hashing is fine but slower.
Never store MD5/SHA of passwords. Use bcrypt/argon2 with a salt.
Same hash = byte-identical content. Great for verifying uploads.
