Is SHA-512 more secure than SHA-256?

Both are currently considered cryptographically secure; SHA-512 offers a larger output size and security margin, but SHA-256 is more commonly required by existing standards.

Why is my hash always 128 characters?

SHA-512 always produces a 512-bit hash, represented as 128 hexadecimal characters, regardless of input length.

Is my text uploaded anywhere?

No — hashing uses your browser's built-in Web Crypto API and never leaves your device.

Can I reverse a SHA-512 hash back to the original text?

Not directly — hashing is one-way by design and considered computationally infeasible to reverse.

Is SHA-512 slower than SHA-256?

Not necessarily — SHA-512's 64-bit internal operations can make it faster than SHA-256 on modern 64-bit processors.

Which hash should I use if a system doesn't specify?

SHA-256 is the more commonly expected default; use SHA-512 only if a system specifically calls for it.

What Is a SHA-512 Hash?

SHA-512 is a cryptographic hash function from the same SHA-2 family as SHA-256, but it produces a longer, 128-character hexadecimal hash (512 bits) using 64-bit internal operations, which can make it faster than SHA-256 on 64-bit hardware despite the longer output.

It is used anywhere a very high security margin or longer hash length is desired, including some password-hashing schemes, certificate systems, and data-integrity applications.
