> Public low-code contract, signatures and examples for util.rsaVerify.

## `util.rsaVerify()`

Verifies an RSA-PSS SHA-256 signature asynchronously, preserving automatic salt-length detection.

### Signature

```ts theme={null}
static rsaVerify(
      publicKey: string,
      payload: string,
      signature: string,
    ): Promise<boolean>;
```

### Example

```ts theme={null}
const ok = await util.rsaVerify(publicKey, 'hello', signature);
```
