Class KeyPairCache

java.lang.Object
org.globus.gsi.gssapi.KeyPairCache

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.

      public KeyPair getKeyPair(int bits) throws NoSuchAlgorithmException, NoSuchProviderException
      Returns a key pair of size bits. 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.
