Hashing is one-way for practical purposes, but hashes are not encryption. Text is encoded as UTF-8 and processed locally with the browser Web Crypto API.
How it works
Generate a precise digest without sending text anywhere.
Enter text, choose a SHA algorithm, and generate a lowercase hexadecimal digest with native browser cryptography. UTF-8 byte counts make multilingual input explicit.
Security note
Hashing is not encryption. SHA-1 remains available for compatibility but is not suitable for new security-sensitive applications.
