Hex digest
Generate
Paste text to hash, or leave the box empty for the digest of zero bytes.
SHA-512 hashes the same UTF-8 bytes and prints a longer digest, 128 hex characters. Choose it when a list or an API asks for SHA-512 by name.
Uppercase hex switches a-f to A-F. Empty text is the SHA-512 digest of zero bytes.
WebCrypto does not offer MD5, so this page does not compute one. SHA-1 is only for checking old systems and lives on its own algorithm.
It is a longer digest of the same UTF-8 bytes: 128 hex characters instead of 64. Pick it when the system you are checking names SHA-512.
WebCrypto does not offer MD5. This page will not invent an MD5. SHA-1 is only for checking old systems.
No. Empty text is the SHA-512 hash of zero bytes, a fixed hex value, not a blank output.
No. This runs in your browser and the text you paste is never uploaded, logged or stored. Google Analytics records page views and feature use, never content.
Compute a SHA-256 message digest from any text in your browser. The hex updates as you type, and your text is never uploaded.
Check a SHA-1 digest against old systems in your browser. Use it only to compare legacy hashes, and your text is never uploaded.
Sign a message with HMAC-SHA256 in your browser. Put the key on the first line, then the text, and your text is never uploaded.
Generate placeholder words, sentences or paragraphs.
Generate version-4 UUIDs from cryptographic random bytes.
Encode text as a QR code and show it as an image.
Turn text into a valid JSON string literal, or decode one back to plain text.
