HomeSYNOPSIS
aes = cipher.aes()
DESCRIPTION
This function creates a new AES encryption or decryption state handle that can be used to run AES ciphers.
RETURN VALUE
A aes state handle.
NOTES
After obtaining a state handle, it must be initialized with an encryption key.
Use aes:setupEncrypt() or aes:setupDecrypt() depending on the desired processing direction.
If the cipher block chaining operation mode is needed, an initialization vector must be configured using aes:setIV().
