DSAKey Type

Contains the parameters for the DSA algorithm.

Remarks

This type is made up of fields that represent the private and public key parameters used by the DSA algorithm.

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:

The component also includes the PublicKey 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 PublicKey in which case the individual parameters must be sent.

The private key consists of the following parameters:

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

Fields

G
String

Represents the G parameter for the DSA algorithm.

GB
TBytes

Represents the G parameter for the DSA algorithm.

P
String

Represents the P parameter for the DSA algorithm.

PB
TBytes

Represents the P parameter for the DSA algorithm.

PrivateKey
String

This property is a PEM formatted private key. The purpose of this property is to allow easier management of the private key parameters by using only a single value.

PublicKey
String

This property is a PEM formatted public key. The purpose of this property is to allow easier management of the public key parameters by using only a single value.

Q
String

Represents the Q parameter for the DSA algorithm.

QB
TBytes

Represents the Q parameter for the DSA algorithm.

X
String

Represents the X parameter for the DSA algorithm.

XB
TBytes

Represents the X parameter for the DSA algorithm.

Y
String

Represents the Y parameter for the DSA algorithm.

YB
TBytes

Represents the Y parameter for the DSA algorithm.

Constructors

constructor Create();

The default constructor creates a new DSAKey instance but does not assign a public or private key.

constructor Create(valP: TBytes; valQ: TBytes; valG: TBytes; valY: TBytes);

The public key constructor assigns an existing public key.

constructor Create(valP: TBytes; valQ: TBytes; valG: TBytes; valY: TBytes; valX: TBytes);

The private key constructor assigns an existing private key.
