Generate MD5, SHA-1, and SHA-256 Hashes
Hash Generator computes a cryptographic hash of any text you enter using MD5, SHA-1, SHA-256, or SHA-512 — useful for verifying file integrity, generating checksums, or understanding how hashing algorithms transform input data.
How to use
- Type or paste the text you want to hash.
- Select the hash algorithm (MD5, SHA-1, SHA-256, or SHA-512).
- Copy the resulting hash value.
Common use cases
- Verifying that a downloaded file matches its published checksum.
- Generating a hash for a non-sensitive lookup key or cache key.
- Learning how different hashing algorithms produce different-length outputs.
