Create SHA-256, SHA-384, or SHA-512 text digests locally.
Quick answer
Create deterministic SHA-256, SHA-384, or SHA-512 digests from text.
SHA-256 digest
Illustrative view
UTF-8 bytes are processed by the selected one-way SHA algorithm.
Create deterministic SHA-256, SHA-384, or SHA-512 digests from text.
The browser encodes input as UTF-8 and hashes the bytes with Web Crypto without sending them to a server.
SHA-256 of an empty string
A standard 64-character hexadecimal digest
Hash the same text twice
Matching digests
Cryptographic hashes are designed to be one-way; they are not encryption and cannot normally be decoded.
