Question
Can anybody tell me how to generate signature for RSASSA-PKCS1-v1.5
in Java?
I, actually, want to know how do I with java.security.Signature
class.
Do I have to use any 3rd party libraries?
Solution
Sun JCE supports PKCS#1 signature. This is all you have to do,
Signature signer = Signature.getInstance("SHA1withRSA");
signer.initSign(privateKey);
signer.update(message);
byte[] signature = signer.sign();
