Class PKCS1EncodedKeySpec

java.lang.Object

org.jgroups.protocols.kubernetes.pem.PKCS1EncodedKeySpec

public class PKCS1EncodedKeySpec
extends Object

PKCS#1 encoded private key is commonly used with OpenSSL. It provides CRT parameters so the private key operation can be much faster than using exponent/modulus alone, which is the case for PKCS#8 encoded key.

Unfortunately, JCE doesn't have an API to decode the DER. This class takes DER buffer and decoded into CRT key.
