About SHA-512 hashes
A SHA-512 hash is a fixed-length fingerprint of your input, used to verify file integrity, detect changes or compare data without revealing it. The same input always yields the same digest.
It is computed locally in your browser, so your text never leaves your device. For security-sensitive uses choose SHA-256 or stronger — MD5 and SHA-1 are cryptographically broken and suited only to non-security checksums.
SHA-512 is the widest member of the SHA-2 family, producing a 512-bit digest written as 128 hexadecimal characters — twice the width of SHA-256, which gives it a larger security margin against brute-force and collision attacks. Because its internal operations work on 64-bit words, SHA-512 is often faster than SHA-256 on modern 64-bit CPUs despite the longer output. You'll see it in TLS certificates and as the underlying primitive in key-derivation and password-hashing schemes, making it a solid default when you want the strongest standard SHA-2 variant.
Frequently asked questions
How do I generate a SHA-512 hash?
Type or paste your text into the box and the SHA-512 digest appears instantly below, ready to copy — computed entirely in your browser.
Is my input sent to a server?
No. Hashes are computed locally in your browser, so your text never leaves your device and nothing is stored online.
What is a SHA-512 hash used for?
A hash is a fixed-length fingerprint of your input, used to verify file integrity, detect changes, or compare data without revealing it. The same input always produces the same SHA-512 digest.
Can I generate other hashes too?
Yes. MD5, SHA-1, SHA-256, SHA-384 and SHA-512 are all shown at once, so you can copy whichever you need.
Why is a SHA-512 hash 128 characters long, and is that the same as SHA-256 with extra padding?
No — SHA-512 genuinely produces a 512-bit digest, shown as 128 hexadecimal characters (each hex character encodes 4 bits), so it's twice the real width of SHA-256's 64-character output, not padded. The extra bits come from a distinct internal design that uses 64-bit words, giving SHA-512 a larger security margin rather than just a longer string.
