The operation of the AES algorithm is shown inFigure 36-2. The encryption step uses a key that converts the data into an unreadable ciphertext, and then the decryption step uses the same key to convert the ciphertext back into the original data. This type of key is asymmetric...

AES decryption is straightforward and is essentially the same as AES encryption but in reverse. The recipient of the encrypted data also has a copy of the cipher used, so they perform each function in reverse to remove the layers of encryption. The information is sent encrypted over the intern...
The above is the java encryption process, but the key bit 20. If I change the key to 16 bits, the following can be correctly decrypted; but if it is 20 bits, it cannot be decrypted properly. varbizContent='{"serialNumber":"330503JD05000018060401001YDQBWEG","status":38}';varkeyUtf8=C...
