# core::starknet::syscalls::sha256_process_block_syscall

Computes the next SHA-256 state of the input with the given state.

## Signature

```rust theme={null}
pub extern fn sha256_process_block_syscall(state: Sha256StateHandle, input: Box) -> Result> implicits(GasBuiltin, System) nopanic;
```

#### Arguments

* `state` - The current SHA-256 state.
* `input` - The input provided to compute the next SHA-256 state.

#### Returns

* The next SHA-256 state of the input with the givens state.

The system call does not add any padding and the input needs to be a multiple of 512 bits
(== 16 u32 word).
