Hash Generator
SHA-1, SHA-256 and SHA-512 hashes of any text, computed locally via the Web Crypto API.
SHA-1
SHA-256
SHA-512
Note: MD5 is not supported by the browser's Web Crypto API and is omitted here since it's cryptographically broken anyway.
Frequently asked questions
Why is MD5 not included?
MD5 is cryptographically broken (collision attacks are practical) and isn't available via the browser's Web Crypto API — SHA-256 or SHA-512 are the modern replacements for most use cases.
Can I reverse a hash back to the original text?
No — hashing is one-way by design. To verify a match, hash the candidate text again and compare the two hashes.
