WolfSSLRsaVerifyCallback

```
public interface WolfSSLRsaVerifyCallback
```
wolfSSL RSA Verification Callback Interface. This interface specifies how applicaitons should implement the RSA verification callback class to be used by wolfSSL.
After implementing this interface, it should be passed as a parameter to the WolfSSLContext.setRsaVerifyCb() method to be registered with the native wolfSSL library.

```
    RSA verification callback method. This method acts as RSA verification callback.
    
    Parameters:
    
    ssl - the current SSL session object from which the callback was initiated.
    
    sig - the signature to verify
    
    sigSz - length of the signature, sig
    
    out - the verification/output buffer after the decryption process and padding.
    
    outSz - size of the output buffer, out
    
    keyDer - the RSA Public key in ASN1 format
    
    keySz - the length of the key, keyDer, in bytes
    
    ctx - custom user-registered ECC signing context
    
    Returns:
    
    0 upon success, otherwise a negative value on error.
