Member Function Documentation
◆ Initialize() [1/4]
template<class EC >
|
inline |
Initialize an EC Private Key using {GP,x}.
- Parameters
-
params group parameters x the private exponent
This Initialize() function overload initializes a private key from existing parameters.
Definition at line 429 of file eccrypto.h.
◆ Initialize() [2/4]
template<class EC >
|
inline |
Initialize an EC Private Key using {EC,G,n,x}.
- Parameters
-
ec the elliptic curve G the base point n the order of the base point x the private exponent
This Initialize() function overload initializes a private key from existing parameters.
Definition at line 442 of file eccrypto.h.
◆ Initialize() [3/4]
template<class EC >
|
inline |
Create an EC private key.
- Parameters
-
rng a RandomNumberGenerator derived class params the EC group parameters
This function overload of Initialize() creates a new private key because it takes a RandomNumberGenerator() as a parameter. If you have an existing keypair, then use one of the other Initialize() overloads.
Definition at line 455 of file eccrypto.h.
◆ Initialize() [4/4]
template<class EC >
|
inline |
Create an EC private key.
- Parameters
-
rng a RandomNumberGenerator derived class ec the elliptic curve G the base point n the order of the base point
This function overload of Initialize() creates a new private key because it takes a RandomNumberGenerator() as a parameter. If you have an existing keypair, then use one of the other Initialize() overloads.
