## Detailed Description

### template<class T>
class DL_PrivateKey< T >

Interface for Discrete Log (DL) private keys.

Definition at line 1105 of file pubkey.h.

## Member Function Documentation

## ◆ MakePublicKey()

template<class T>

void DL_PrivateKey< T >::MakePublicKey | ( | DL_PublicKey< T > & | pub | ) | const
| inline

Initializes a public key from this key.

Parameters

  pub | reference to a public key

Definition at line 1116 of file pubkey.h.

## ◆ GetVoidValue()

template<class T>

bool DL_PrivateKey< T >::GetVoidValue | ( | const char * | name,
|  | const std::type_info & | valueType,
|  | void * | pValue
| ) |  | const
| inline

Get a named value.

Parameters

  name | the name of the object or value to retrieve
  valueType | reference to a variable that receives the value
  pValue | void pointer to a variable that receives the value

Returns
  true if the value was retrieved, false otherwise

GetVoidValue() retrieves the value of name if it exists.

Note
  GetVoidValue() is an internal function and should be implemented by derived classes. Users should use one of the other functions instead.

  GetValue(), GetValueWithDefault(), GetIntValue(), GetIntValueWithDefault(), GetRequiredParameter() and GetRequiredIntParameter()

Definition at line 1132 of file pubkey.h.

## ◆ AssignFrom()

template<class T>

void DL_PrivateKey< T >::AssignFrom | ( | const NameValuePairs & | source | ) |
| inline

Initialize or reinitialize this key.

Parameters

  source | NameValuePairs to assign

Definition at line 1140 of file pubkey.h.

## ◆ GetPrivateExponent()

template<class T>

virtual const Integer& DL_PrivateKey< T >::GetPrivateExponent | ( |  | ) | const
| pure virtual

Retrieves the private exponent.

Returns
  the private exponent

Must be overridden in derived classes.

Implemented in DL_PrivateKeyImpl< GP >, and DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >.

## ◆ SetPrivateExponent()

template<class T>

virtual void DL_PrivateKey< T >::SetPrivateExponent | ( | const Integer & | x | ) |
| pure virtual

Sets the private exponent.

Parameters

  x | the private exponent

Must be overridden in derived classes.

Implemented in DL_PrivateKeyImpl< GP >, and DL_PrivateKeyImpl< DL_GroupParameters_EC< EC > >.
