# SHA-512 Generator

Generate the SHA-512 hash of any text with this SHA-512 Generator. Enter text and the tool encodes it as UTF-8, computes the 512-bit SHA-2 digest and returns a 128 character lowercase hexadecimal string, identical to sha512sum, OpenSSL and standard libraries. Built for developers and administrators who need the longest SHA-2 fingerprint for checksums, integrity checks, test vectors and comparing values across systems.

## Frequently asked questions

### What does the SHA-512 Generator return?

It returns the SHA-512 digest of your text as 128 lowercase hexadecimal characters, which encode 512 bits. The same text always gives the same hash.

### What is the SHA-512 hash of hello?

The lowercase word hello without a newline hashes to a value that starts with 9b71d224bd62f378 and ends with 73bcdec043. Run the tool on hello to see the full 128 characters and compare them with your own code.

### Why is my hash different from another tool's?

The tool hashes the text exactly as entered, including trailing spaces and line breaks. A newline added by echo or CRLF line endings from Windows change the whole hash.

### How is non-ASCII text encoded?

Text is encoded as UTF-8 before hashing, the default for most languages, terminals and web APIs. Other encodings of the same characters produce different bytes and therefore a different hash.

### Is SHA-512 more secure than SHA-256?

Both are secure members of the SHA-2 family with no known practical attacks. SHA-512 has a longer output and a larger security margin, and it is often faster than SHA-256 on 64-bit processors.

### Is SHA-512 the same as SHA-512/256 or SHA3-512?

No. SHA-512/256 is a truncated variant with different initial values, and SHA3-512 belongs to the separate SHA-3 family, so both give different results. This tool computes standard SHA-512 only.

### Should I hash passwords with SHA-512?

Not on its own. A single fast SHA-512 pass makes password guessing cheap, so use a slow, salted password hashing algorithm such as Argon2 or bcrypt instead.

### Can I hash a file?

The tool hashes text you paste or type, not uploaded files. For binary files use sha512sum on Linux, shasum -a 512 on macOS or Get-FileHash -Algorithm SHA512 in PowerShell.

### Does the tool use a key or salt?

No, it computes a plain SHA-512 digest without any key or salt. HMAC-SHA512 signatures need a secret key and give a different value.

### How much text can I hash?

Enter at least one character and up to 5 MB of text; larger input is rejected with a message. The result matches the SHA-512 option of the Hash Generator.
