Details
Paste text, pick an algorithm, and hash. Output is lowercase hex. Use SHA-256 for most everyday fingerprints unless a protocol specifies otherwise.
Do not use a bare hash as a password storage scheme. Password hashing needs a dedicated KDF with salt (for example Argon2 or bcrypt) in your application stack.
Frequently asked questions
- Which algorithms are supported?
- SHA-256, SHA-384, and SHA-512 through the Web Crypto API available in modern browsers.
- Is hashing done locally?
- Yes. The digest never leaves your browser tab.
- Is a hash encryption?
- No. Hashes are one-way digests for integrity checks and fingerprints, not reversible encryption.
