How to use the Hash Generator
Generate standard SHA-family message digests from text using your browser's built-in Web Crypto API.
- Paste or type the input text.
- Choose a supported SHA algorithm.
- Fieldlet encodes the text as UTF-8, hashes it locally, and displays the hexadecimal digest.

Common questions
Can I reverse a cryptographic hash?
No. Cryptographic hash functions are designed to be one-way; this tool generates digests rather than decoding them.
Should I use SHA-1 for security?
No. SHA-1 is included only for legacy compatibility and checksums. Use a modern algorithm such as SHA-256 or stronger for current security-sensitive work.
