About Hash Generator
Generate cryptographic hashes from text or files using MD5, SHA-1, SHA-256, or SHA-512 algorithms. Hashes are one-way functions—you can verify data matches a known hash, but you can't reverse it to get the original.
Use this tool to verify file integrity after downloads, create checksums for your releases, or understand how hashing works. All processing happens in your browser—your data isn't uploaded anywhere.
How to use Hash Generator
Select your hash algorithm (SHA-256 is a good default).
Type or paste text, or upload a file.
The hash appears immediately.
Compare with a known hash to verify integrity.
Copy the hash for documentation or verification.
Examples
MD5 hash
MD5 produces a 128-bit (32 hex character) hash. Fast but not cryptographically secure:
Input: Hello, World! MD5: 65a8e27d8879283831b664bd8b7f0ad4
SHA-256 hash
SHA-256 is the current standard. Produces a 256-bit (64 hex character) hash:
Input: Hello, World! SHA-256: dffd6021bb2bd5b0af676290809ec3a53191dd81c7f70a4b28688a362182986f
Verifying a file download
Compare your hash against the publisher's to ensure the file wasn't corrupted or tampered with:
Publisher says: e3b0c44298fc1c149afbf4c8996fb924... Your file hash: e3b0c44298fc1c149afbf4c8996fb924... ✓ Match - file is authentic Your file hash: 7f83b1657ff1fc53b92dc18148a1d65d... ✗ Different - file may be corrupted
