CreateKey Method

Creates a new key.

Syntax

 int CreateKey();

Remarks

This method creates a new public and private key.

When calling CreateKey the Key* properties are populated with a new private and public key.

RSA Keys

A RSA key is made up of a number of individual parameters.

The public key consists of the following parameters:

• KeyModulus
• KeyExponent

The class also includes the KeyPublicKey property which holds the PEM formatted public key for ease of use. This is helpful if you are in control of both sides of the encryption/signing and decryption/signature verification process. When sending the public key to a recipient note that not all implementations will support using the PEM formatted value in KeyPublicKey in which case the individual parameters must be sent.

The private key may be represented in one of two ways. Both are mathematically equivalent. Private key format 1:

• KeyModulus
• KeyP
• KeyQ
• KeyDP
• KeyDQ

Private key format 2 is simpler but has decreased performance when decrypting and signing. This format is:

• KeyModulus
• KeyD

The class also include the KeyPrivateKey property which holds the PEM formatted private key for ease of use. This is helpful for storing the private key more easily.
