Security exception error while trying to decrypt.

[AppleDecryptorRJ]

Hello,

I've been trying to decrypt the apple pay token with beatty/applepay_crypto_demo program.

I loaded the message.json file, the .p12 file and the .cer files in the appropriate parts of the code, but I got an exception message as in,

Exception in thread "main" java.io.IOException: error constructing MAC: java.lang.SecurityException: JCE cannot authenticate the provider BC
at org.bouncycastle.jce.provider.JDKPKCS12KeyStore.engineLoad(JDKPKCS12KeyStore.java:716)
at java.security.KeyStore.load(Unknown Source)
at Main.loadPrivateKey(Main.java:178)
at Main.main(Main.java:116)

when I tried and followed some online helper forums, now its throwing another exception,

Exception in thread "main" java.io.IOException: exception unwrapping private key - java.security.InvalidKeyException: Illegal key size
at org.bouncycastle.jce.provider.JDKPKCS12KeyStore.unwrapKey(Unknown Source)

at java.security.KeyStore.load(Unknown Source)
at Main.loadPrivateKey(Main.java:158)
at Main.main(Main.java:110)

I'm really led out of this place here. Its really important to get this thing working. Am I doing something wrong here?? can someone help me out of this situation please. Its really important, any thoughts would be appreciated. Thanks in advance.
