Examples of net.oauth.signature.pem.PKCS1EncodedKeySpec

net.oauth.signature.pem.PKCS1EncodedKeySpec
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. @author zhang
