Hash Generator
Create SHA-256 or SHA-1 digests of text in the browser with the Web Crypto API for checksums, cache keys, and non-secret fingerprints.

Hash, AES-GCM, encoding.
Hash text, encrypt with AES-GCM, or encode and decode Base64 and other formats. These run entirely in the browser so you can work with sensitive data locally.
This category is for developers and technical users who need hashing, encryption, or encoding: checksums, password-based encryption, or safe handling of binary-like data in text form.
Common tasks include hashing text with SHA-256 or SHA-1, encrypting or decrypting a short message with a passphrase (AES-GCM), and encoding or decoding Base64 or URL-safe strings. Crypto primitives run in the browser; nothing is sent to our servers for those transforms.
Use the hash generator for integrity checks or non-secret fingerprints. Use AES-GCM when you need to encrypt/decrypt with a password. For encoding only (no secrecy), use Base64 or URL tools under Text Tools.
