Generate cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for texts and files, and verify checksum integrity.
Select either the Text or File tab.
Enter text or drop any file into the upload zone.
Hashes for MD5, SHA-1, SHA-256, and SHA-512 are calculated immediately.
Paste the original checksum in the verification box to confirm authenticity.
Yes, files are streamed and hashed in memory by your browser's Web Crypto API without uploading to any remote server.
MD5 is fast for non-critical integrity checks, whereas SHA-256 is the modern cryptographic industry standard.
