<br>
I've got the following results with your examples :<br>
<br>
JWE.log :<br>
<br>
I'm unable to get the same encrypted key using either the private or public part of the given key. However, I am able to decrypt your encrypted key with no problem. Since it's only using PCKS1-v1_5, I believe I should be able to get the same encrypted key value.<br>
<br>
The CEK and CIK and ciphertext results are the same.<br>
<br>
Using your encrypted key gives me the same results for the integrity value.<br>
<br>
<br>
JWE2.log :<br>
<br>
Due to the RSA-OAEP algorithm, I can only perform decryption on your encrypted key. The decrypted value matches your CMK.<br>
Using your AAD, the I was able to successfully decrypt and verify your data.<br>
