How do I get javax.crypto classes such as javax.crypto.Cipher to work on a servlet with jboss?
Date : March 29 2020, 07:55 AM
help you fix your problem I figured out what was wrong with my code. Earlier in the code for some reason someone did the following: if (SunJCEinProviders)
{
Security.removeProvider("SunJCE");
}
int i = Security.insertProviderAt(new com.sun.crypto.provider.SunJCE(),1);

java.lang.IllegalAccessError: tried to access class javax.crypto.Cipher$Transform from class javax.crypto.Cipher

hope this fix your issue This crypto error is coming due to conflicting jce.jar in the jms and the openjdk. Issue was resolved by commenting out this line in standalone.xml: <--module name="org.jboss.genericjms.provider" slot="main"-->

Java - Difference between javax.crypto.Mac and javax.crypto.Cipher?
Date : March 29 2020, 07:55 AM
With these it helps A Message Authentication Code is for integrity. It computes, on some input message, a kind of "keyed checksum" that depends on the message and on the key. With knowledge of the key, the MAC can be verified to match a given message. Alterations are thus reliably detected. A Symmetric encryption algorithm is for confidentiality. It transforms a message into an unreadable sequence of bits; the encryption is reversible provided that the decryption key is known.

I hope this helps you . I'm trying to convert below java code into nodejs. , Just need to change - function freeChargeEncryptAES(token){
var fcKey = "11111111111111111111".substring(0, 16);
var cipher = crypto.createCipheriv('aes-128-ecb', fcKey, "");
var encrypted = cipher.update(token,'ascii','hex');
encrypted += cipher.final('hex');
return encrypted;
}
