CONSOLE MESSAGE: AES-CBC and AES-CTR do not provide authentication by default, and implementing it manually can result in minor, but serious mistakes. We recommended using authenticated encryption like AES-GCM to protect against chosen-ciphertext attacks.

We recommended using authenticated encryption like AES-GCM to protect against chosen-ciphertext attacks. Test encrypting&decrypting using AES-CBC algorithm with a generated 256bit key On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". Generating a key... Encrypting... PASS bytesToASCIIString(cipherText) is not "Hello, World!" Decrypting... PASS bytesToASCIIString(decryptedText) is plainText PASS successfullyParsed is true TEST COMPLETE
