How it works

Enter your text or file

Type or paste text, or drop a file of up to 500 MB. Nothing is uploaded.

Read the SHA-512 hash

The hash updates as you type. Choose lowercase or uppercase hexadecimal, or Base64.

Copy or compare

Copy the hash with one click, or paste a known hash in the compare box to check that they match.

How to generate a SHA-512 hash

To generate a SHA-512 hash, type or paste your text in the box above, or drop a file on it. The 128-character SHA-512 checksum appears at once, together with the other common hashes, and you can copy any of them. Everything is computed in your browser, so the text and files you hash are never uploaded. For example, the SHA-512 of the word hello is 9b71d224bd62f3785d96d46ad3ea3d73319bfbc2890caadae2dff72519673ca72323c3d99ba5c11d7c7acc6e14b8c5da0c4663475c2e5c3adef46f73bcdec043.

What is SHA-512?

SHA-512 belongs to the SHA-2 family, published by NIST in 2001, and produces a 512-bit fingerprint written as 128 hexadecimal characters. It works on 64-bit words, so on modern 64-bit processors it is often as fast as SHA-256 or faster for large inputs, while giving a much longer digest.

What SHA-512 is used for

  • Long-term integrity checks where a bigger safety margin is wanted than SHA-256 provides.
  • Unix password files, where the $6$ scheme (sha512crypt) repeats SHA-512 thousands of times with a salt.
  • Ed25519 signatures, which use SHA-512 internally.
  • Derived keys, for example HMAC-SHA512 in HD wallets and PBKDF2-HMAC-SHA512.

Limits and security notes

A longer hash is not automatically a better password hash. Plain SHA-512 is still very fast, so it should not be used on its own to store passwords; use Argon2id, bcrypt or scrypt instead. For everyday integrity checks, SHA-256 is enough, shorter to copy and more widely published by software vendors.

Private by design

The hash is computed by your own browser with the Web Crypto API (and a built-in routine for MD5, which Web Crypto does not offer). Nothing you type and no file you drop is sent to a server, so it is safe to hash private text and internal files.

Frequently asked questions

How long is a SHA-512 hash?
128 hexadecimal characters, which is 512 bits, for any input. That is exactly twice the length of SHA-256.
Is SHA-512 more secure than SHA-256?
It has a larger output and internal state, so its theoretical security margin is bigger, but both are considered secure today. Pick the one the system you are working with expects.
Why does the tool also show SHA-1, SHA-256 and MD5?
Because they are computed from the same input at the same time, so you can copy whichever one you need without retyping the text.
Are the hashes case sensitive?
The hexadecimal digits a-f and A-F mean the same thing, so a hash in uppercase is equal to the same hash in lowercase. Use the uppercase option only when the system you copy it into expects that format.
Is this converter free?
Yes. There is no sign-up and no limit, and it runs in your browser, so nothing you type is sent to a server.
Does it work on a phone?
Yes. It works in any modern mobile browser, and the result updates as you type.
