FAQ
Is SHA-512 secure?
Yes — SHA-512 is part of the SHA-2 family and is currently considered secure for integrity checks and most cryptographic uses, with a larger digest than SHA-256.
Should I use SHA-512 instead of SHA-256?
Both are currently considered secure. SHA-512 produces a longer digest and can be faster on 64-bit hardware; SHA-256 is more common in checksum listings. Use whichever the source you're verifying against provides.
How long is a SHA-512 hash?
512 bits, shown here as 128 hexadecimal characters.
Is my text or file uploaded anywhere?
No — the SHA-512 hash is calculated locally in your browser using the browser's own cryptographic API.
