myPKEModule.VerifySignature(signature, signedData);
| myPKEModule | The name of the Public Key Encryption module structure |
| signature | The Digital signature to verify |
| signedData | Data used to create the signature in DATA format |
| Return: | A BOOLEAN value to indicate verification |
The VerifySignature function verifies the given digital signature using the options specified in the Public Key Encryption From Buffer module definition.
