Encrypt and decrypt data with the Elgamal asymmetric key encryption algorithm for public-key cryptography.
The ElGamal component is used to encrypt/decrypt data with the Elgamal asymmetric key encryption algorithm for public-key cryptography.
Input and Output Properties
The component will determine the source and destination of the input and output based on which properties are set.
The order in which the input properties are checked is as follows:
When a valid source is found the search stops. The order in which the output properties are checked is as follows:
- OutputMessage: The output data is written to this property if no other destination is specified.
An Elgamal key is made up of a number of individual parameters.
The public key consists of the following parameters:
The component also includes the PublicKey field which holds the PEM formatted public key for ease of use. This is helpful if you are in control of both signature creation and verification process. When sending the public key to a recipient note that not all implementations will support using the PEM formatted value in PublicKey in which case the individual parameters must be sent.
The private key consists of the following parameters:PrivateKey field which holds the PEM formatted private key for ease of use. This is helpful for storing the private key more easily.
