Tool Introduction
Calculate SHA-1, SHA-2 (224/256/384/512) and SHA-3 (256/512) one-way digests for any text or file. Results are computed locally in your browser, so nothing is sent to a server.
A hash is a fixed-length fingerprint of your input, not encryption: it cannot be reversed to recover the original message. Use SHA-256 or SHA-3 for new work - SHA-1 is kept only for compatibility with legacy systems and is no longer considered secure.
