DHGenParameterSpec
open class DHGenParameterSpec : AlgorithmParameterSpec
This class specifies the set of parameters used for generating Diffie-Hellman (system) parameters for use in Diffie-Hellman key agreement. This is typically done by a central authority.
The central authority, after computing the parameters, must send this information to the parties looking to agree on a secret key.

DHGenParameterSpec
DHGenParameterSpec(
primeSize: Int,
exponentSize: Int)
Constructs a parameter set for the generation of Diffie-Hellman (system) parameters. The constructed parameter set can be used to initialize an AlgorithmParameterGenerator object for the generation of Diffie-Hellman parameters.
| Parameters |
primeSize |
Int: the size (in bits) of the prime modulus. |
exponentSize |
Int: the size (in bits) of the random exponent. |
Public methods
getExponentSize
open fun getExponentSize(): Int
Returns the size in bits of the random exponent (private value).
| Return |
Int |
the size in bits of the random exponent (private value) |
getPrimeSize
open fun getPrimeSize(): Int
Returns the size in bits of the prime modulus.
| Return |
Int |
the size in bits of the prime modulus |
