DSA Key Notes

A DSA key is made up of a number of individual parameters. When calling CreateKey the Key* properties are populated with a new private and public key.

After calling Sign the public key must be sent to the recipient along with HashSignature so they may perform signature verification. Likewise you must obtain the public key along with HashSignature in order to perform signature verification.

The public key consists of the following parameters:

• KeyP
• KeyQ
• KeyG
• KeyY

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 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 KeyPublicKey in which case the individual parameters must be sent.

The private key consists of the following parameters:

• KeyP
• KeyQ
• KeyG
• KeyY
• KeyX

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.
