Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes from any text, each shown separately or copied together as one combined block.
MD5: SHA-1: SHA-256: SHA-384: SHA-512:
SHA-256 is the standard choice for most modern uses. MD5 and SHA-1 are still common for checksums but shouldn't be relied on for security.
No — every hash is computed entirely in your browser using the Web Crypto API.
No — a hash is one-way. You can verify text matches a known hash, but you can't recover the original text from the hash alone.
