Xceed Encryption Library Documentation
This Signing Method object represents the RSA digital signature algorithm.
After you have either created an instance of this object (or obtained one by reading the contents of the Xceed Signing control's SigningMethod property), you can set its properties and then assign it to the Xceed Signing control's SigningMethod property. Set the PrivateKey property if you are going to digitally sign data with the Sign method. Set the PublicKey property if you will verify data against a digital signature using the Verify method.
The SubProcessing property allows further operations to be efficiently performed on the source data. For example, it allows the source data that was used to create a digital signature to be passed to the Xceed Encryption or Xceed Hashing objects or to other compatible Xceed component objects such as the ones from the Xceed Streaming Compression Library or the Xceed Binary Encoding Library.
