## Detailed Description

Interface for crypto material.

GeneratableCryptoMaterial() is an interface for crypto material, such as private keys and crypto parameters. Derived classes offer public methods such as GenerateRandom() and GenerateRandomWithKeySize().

## Member Function Documentation

## ◆ GenerateRandom()

virtual void GeneratableCryptoMaterial::GenerateRandom | ( | RandomNumberGenerator & | rng,
|  | const NameValuePairs & | params = `g_nullNameValuePairs`
| ) |  |
| inline virtual

Generate a random key or crypto parameters.

Parameters

  rng | a RandomNumberGenerator to produce keying material
  params | additional initialization parameters

Exceptions

  KeyingErr | if a key can't be generated or algorithm parameters are invalid

If a derived class does not override GenerateRandom(), then the base class throws NotImplemented.

Reimplemented in ed25519PrivateKey, x25519, DL_PrivateKeyImpl< GP >, InvertibleRWFunction, InvertibleRSAFunction, InvertibleRabinFunction, InvertibleLUCFunction, DL_GroupParameters_DSA, DL_GroupParameters_IntegerBased, InvertibleESIGNFunction, and DL_GroupParameters_EC< EC >.

## ◆ GenerateRandomWithKeySize()

void GeneratableCryptoMaterial::GenerateRandomWithKeySize | ( | RandomNumberGenerator & | rng,
|  | unsigned int | keySize
| ) |  |

Generate a random key or crypto parameters.

Parameters

  rng | a RandomNumberGenerator to produce keying material
  keySize | the size of the key, in bits

Exceptions

  KeyingErr | if a key can't be generated or algorithm parameters are invalid

GenerateRandomWithKeySize calls GenerateRandom() with a NameValuePairs object with only "KeySize"
