Important
SHA-512 is a fast general-purpose digest. It must not replace a salted password-hashing function.
How to use this sha-512 hash generator
- Enter the exact UTF-8 input.
- Run the generator with SHA-512 selected.
- Copy the 128-character hexadecimal result.
SHA-512 output specification
SHA-512 processes 1024-bit blocks and returns 512 digest bits. Code Compass delegates the calculation to Web Crypto and renders the result as lowercase hexadecimal.
| Property | Value |
|---|---|
| Digest | 512 bits |
| Hex output | 128 characters |
| Block size | 1024 bits |
Worked example
Enter hello, keep SHA-512 selected and run the tool. The result begins 9b71d224bd62f378 and contains 128 hexadecimal characters.
SHA-512 questions
Is SHA-512 a SHA-2 algorithm?
Yes. SHA-256 and SHA-512 are both members of SHA-2.
Can I compare SHA-512 and SHA-256 directly?
No. They have different output sizes and produce different digests.
Should I hash passwords with plain SHA-512?
No. Use a dedicated salted password-hashing scheme.
