## Detailed Description

Digital Signature Algorithm Private Key.

## Constructor & Destructor Documentation

QCA::DSAPrivateKey::DSAPrivateKey | ( |  | ) |

Create an empty DSA private key.

QCA::DSAPrivateKey::DSAPrivateKey | ( | const DLGroup & | domain,
|  | const BigInteger & | y,
|  | const BigInteger & | x,
|  | const QString & | provider = `QString()`
| ) |  |

Create a DSA public key.

Parameters

  domain | the discrete logarithm group to use
  y | the public random value
  x | the private random value
  provider | the provider to use, if a specific provider is required

## Member Function Documentation

DLGroup QCA::DSAPrivateKey::domain | ( |  | ) | const

The discrete logarithm group that is being used.

BigInteger QCA::DSAPrivateKey::y | ( |  | ) | const

the public random value

BigInteger QCA::DSAPrivateKey::x | ( |  | ) | const

the private random value
