SHA-256, SHA-384 and SHA-512 Hash Generator
Generate a SHA-2 hash from text using the browser's Web Crypto API. Your input is processed on your device and is not uploaded.
Hashes UTF-8 text locally with Web Crypto. A hash is one-way and is not encryption or a substitute for password hashing.
How to generate a text hash
Select SHA-256, SHA-384 or SHA-512, enter the text and choose Generate hash. The tool encodes the text as UTF-8 before computing the digest, then displays it as lowercase hexadecimal.
Hashing is not encryption
A cryptographic hash is a one-way digest, not a way to encrypt text and recover it later. Do not use a general-purpose SHA-2 hash alone to store passwords; password storage should use a dedicated, salted password-hashing algorithm.
Encode text for transport with the Base64 Converter, or format structured data with the JSON Formatter, or convert design color values with the Color Converter.
