Hash Generator
Hash text or files with the browser's built-in WebCrypto — data never leaves your device.
Frequently asked questions
Which hash should I use?
SHA-256 is the modern default for checksums and integrity verification. SHA-512 offers a larger digest. SHA-1 is provided only for compatibility with older systems — it is considered broken for security purposes and should not protect anything important.
Why is MD5 not offered?
Browsers' WebCrypto API deliberately excludes MD5 because it has been cryptographically broken for two decades. If a legacy system demands MD5, use a command line tool, but prefer SHA-256 anywhere you have a choice.
Can I verify a downloaded file's checksum here?
Yes. Choose the file, pick the algorithm the publisher used (usually SHA-256), and compare the result to the published checksum. Matching hashes mean the file arrived intact.
Is hashing the same as encryption?
No. A hash is a one-way fingerprint: you cannot recover the original data from it. Encryption is reversible with a key. Hashes verify integrity; encryption protects confidentiality.
