Hash and UUID Generator — MD5, SHA-256
Compute MD5, SHA-1, SHA-256 and SHA-512 for text or files to verify downloads, and generate UUID v4 in bulk.
Processed locally in your browser. Nothing is uploaded.
How to use
- Enter text or choose a file.
- Copy the hash for each algorithm.
- Generate UUIDs in bulk if needed.
Example and rules
Example: the SHA-256 of abc is ba7816bf…f20015ad.
- Text is hashed as UTF-8; files up to 500 MiB.
- SHA uses Web Crypto; MD5 is for legacy checksums.
- UUIDs use a cryptographically secure random source.
Frequently asked questions
How do I verify a download?
Pick the file and compare the SHA-256 with the one published by the vendor.
Is MD5 still secure?
Not for security, but it is fine for basic integrity checks.
Are files uploaded?
No. Hashes are computed locally.
