What is SHA-512/256?
SHA-512/256 is a cryptographic hash function: it takes input of any length and produces a fixed-length 256-bit output, written as 64 hexadecimal characters. The same input always gives the same hash, but changing even a single character produces a completely different result.
SHA-512/256 uses the SHA-512 engine with unique initial values and truncates the result to 256 bits. It produces a SHA-256-sized hash but is often faster on 64-bit hardware.
It is secure and resists length-extension attacks, making it a smart alternative to SHA-256.

Frequently asked questions
Can a SHA-512/256 hash be decrypted?
No. Hashing is one-way; there is no key to reverse it. Weak or common inputs can sometimes be guessed with lookup tables, which is why passwords need salting and slow algorithms.
Is SHA-512/256 safe for storing passwords?
No fast hash, including SHA-512/256, should be used alone for passwords. Use our Bcrypt Generator or another slow, salted algorithm instead.
Why is my SHA-512/256 hash different from another tool?
Hidden spaces, line breaks or a different character encoding change the input and therefore the hash. Make sure the text is exactly the same.
