JWT-RSA

JWT-RSA is library for JWT encrypt and decrypt using RSA key. For encrypt, we use public key and for decrypt we use private key.

How To Use

When you use this library, you can generate public and private key using command openssl like this.

for generate private key

openssl genrsa -passout pass:"rizkimufrizal" -des3 -out private.pem 2048

for generate public key

openssl rsa -in private.pem -outform PEM -pubout -out public.pem -passin pass:"rizkimufrizal"

convert private key to pkcs8 format in order to import it from kotlin

openssl pkcs8 -topk8 -in private.pem -inform pem -out private_key_pkcs8.pem -outform pem -nocrypt -passin pass:"rizkimufrizal"

or convert private key to unecnrypted format in order to import it from kotlin

openssl rsa -in private.pem -out private_unencrypted.pem -outform PEM -passin pass:"rizkimufrizal"

You can use one of the private keys. In this example, we use private key in pkcs8 format.

Algorithm And Encryption Methods

You can use of this list algorithm :

  • RSA1_5
  • RSA-OAEP
  • RSA-OAEP-256
  • A128KW
  • A128GCMKW
  • A256KW
  • A256GCMKW
  • DIR
  • ECDH-ES
  • ECDH-ES+A128KW
  • ECDH-ES+A192KW
  • ECDH-ES+A256KW
  • PBES2-HS256+A128KW
  • PBES2-HS384+A192KW
  • PBES2-HS512+A256KW

You can use of this list encryption methods :

  • A128GCM
  • A192GCM
  • A256GCM
  • A128CBC-HS256
  • A192CBC-HS384
  • A256CBC-HS512

            val encryptedString = EncryptGenerator.generateEncrypt(plainText = "Hy Rizki Mufrizal", path = "/Users/rizkimufrizal/Documents/keys", fileName = "public.pem", jWEAlgorithm = "RSA-OAEP-256", encryptionMethod = "A256CBC-HS512")

            println(encryptedString)

            val plainText = encryptedString?.let { DecryptGenerator.generateDecrypt(encryptText = it, path = "/Users/rizkimufrizal/Documents/keys", fileName = "private_key_pkcs8.pem") }

            println(plainText)
        }
    }
}

this for example when using groovy

import org.rizki.mufrizal.jwt.rsa.DecryptGenerator
import org.rizki.mufrizal.jwt.rsa.EncryptGenerator

class App {
    static void main(String[] args) {
        def encryptedString = EncryptGenerator.generateEncrypt("Hy Rizki Mufrizal", "/Users/rizkimufrizal/Documents/keys", "public.pem", "RSA-OAEP-256", "A256CBC-HS512")

        println(encryptedString)

        def plainText = DecryptGenerator.generateDecrypt(encryptedString, "/Users/rizkimufrizal/Documents/keys", "private_key_pkcs8.pem")

        println(plainText)
    }
}

this for example when using java

import org.rizki.mufrizal.jwt.rsa.DecryptGenerator;
import org.rizki.mufrizal.jwt.rsa.EncryptGenerator;

public class App {
    public static void main(String[] args) {
        String encryptedString = EncryptGenerator.generateEncrypt("Hy Rizki Mufrizal", "/Users/rizkimufrizal/Documents/keys", "public.pem", "RSA-OAEP-256", "A256CBC-HS512");

        System.out.println(encryptedString);

        String plainText = DecryptGenerator.generateDecrypt(encryptedString, "/Users/rizkimufrizal/Documents/keys", "private_key_pkcs8.pem");

        System.out.println(plainText);
    }
}
