Short: How to Decrypt the file which is already Encrypted by PGP tool by using Java.
Hi All,
Detail: I need a solution (but i don't know it was possible or not? ) I have some of the files with Encrypted by PGP third patry tool (ex:XXXXXX.pgp)and i have KeyFile called abc.skr(this file is combination of PrivateKey and Public Key). Now i want to Decrypt the file with Java progarmme. Can u please help me what exactly i suppose to do..?
Here my code:
try
{
FileInputStream keyfis = new FileInputStream ("D:\\punna_Decrypt\\classes\\abc.skr");// Keypair file reding
byte[] encKey = new byte[keyfis.available()];
keyfis.read(encKey);
// KeyPairGenerator generator = KeyPairGenerator.getInstance("DSA");
PKCS8EncodedKeySpec privKeySpec = new KCS8EncodedKeySpec(encKey);
KeyFactory keyFactory = KeyFactory.getInstance("DSA");
PrivateKey privKey = keyFactory.generatePrivate(privKeySpec);
// the Exception is:
java.security.spec.InvalidKeySpecException: Inappropriate key specification: invalid key format
I was new for security concepts, i gone through some of the cryptography doucements for gathering information but stil i was dylama... (
