help
help encrypt or help decrypt
Not being 128, 192, or 256 bits leads to an error.
Shorter than 128 bits, error.
Add a 0 to the last second position when the
length is odd. Example:5072656E7469636548616C6C496E632 considered as 5072656E7469636548616C6C496E6302
Longer than 128 bit, only first 128 bits count.
Specially, iv length can be any in GCM mode.
Since padding function is used, the length does not matter. Also, add a 0 to the last second position when the
length is odd.
Can be any length.
Be specified as 128bit.
