public class KeyPairCache extends Object
Simple cache for key pairs. The cache is used to avoid excessive CPU consumption from key pair generation. In particular for purposes of delegation, reusing a key pair is safe.- Author:

getKeyPair
public KeyPair getKeyPair(int bits) throws NoSuchAlgorithmException, NoSuchProviderException
Returns a key pair of sizebits
. The same key pair may be returned several times within a period of the cache lifetime. If lifetime was set to zero or less than zero, no keys are cached.- Parameters:
bits
- the keysize. This is an algorithm-specific metric, such as modulus length, specified in number of bits.- Throws:
NoSuchAlgorithmException
- if the algorithm is not available in the environment.NoSuchProviderException
- if the provider is not available in the environment.
