Runs the squeeze phase

## NAME

libkeccak\_squeeze - Runs the squeeze phase

## SYNOPSIS

```
#include <libkeccak.h>
void libkeccak_squeeze(struct libkeccak_state *state, void *hashsum);
```

Link with *-lkeccak*.

## DESCRIPTION

The **libkeccak\_squeeze**() function runs the Keccak squeeze phase, on the the hash process described by *\*state*, on stores a new digest, in binary form, in *hashsum*.

*hashsum* has the same requirement as for the [**libkeccak\_digest**(3)](/libkeccak_digest/3.md) and [**libkeccak\_fast\_digest**(3)](/libkeccak_fast_digest/3.md) functions: it must have an allocation size of at least ((*state-\>n* + 7) / 8) bytes. However, it may not be *NULL*.

## RETURN VALUES

The **libkeccak\_squeeze**() function does not return any value.

## ERRORS

The **libkeccak\_squeeze**() function cannot fail.
