What is SHA-512?
SHA-512 is a cryptographic hash algorithm from the SHA-2 family. It creates a 512-bit hash, usually shown as a 128 character hexadecimal string.
ALT SHA-512 Hash Generator
Type or paste text below to instantly generate a SHA-512 hash. All processing happens locally in your browser.
ALT SHA-512 Hash Generator creates a 512-bit SHA-2 hash from text, strings, or test values. SHA-512 is often used for integrity checks, cryptographic workflows, and comparing data when a longer digest is useful. It is not encryption, so a SHA-512 hash can be checked or verified but not decrypted back to text.

SHA-512 Questions
How does SHA-512 work?
SHA-512 processes input data in blocks and produces a fixed length digest. Even a small change in the input creates a very different hash, which makes it useful for integrity checks.
Can SHA-512 be decrypted?
No. SHA-512 is a one way hash, not encryption. You can verify a value by hashing it again, but you cannot decrypt SHA-512 back to the original text.
Is SHA-512 secure?
SHA-512 is still considered secure for integrity checks and many cryptographic workflows. For password storage, use bcrypt, Argon2, or another dedicated password hashing algorithm.
What is the difference between SHA-256 and SHA-512?
SHA-256 creates a 256-bit hash, while SHA-512 creates a 512-bit hash. Both are part of SHA-2 and are widely used, but SHA-512 outputs a longer digest.
How do I check a SHA-512 checksum on Linux or Windows?
On Linux, sha512sum is commonly used. On Windows, PowerShell can calculate file hashes with Get-FileHash using SHA512. This page generates SHA-512 from text, while the ALT file checksum verifier is better for files.
