### cipher.setAutoPadding(auto_padding=true)

You can disable automatic padding of the input data to block size. If `auto_padding` is false,
the length of the entire input data must be a multiple of the cipher's block size or `final` will fail.
Useful for non-standard padding, e.g. using `0x0` instead of PKCS padding. You must call this before `cipher.final`.

### decipher.setAutoPadding(auto_padding=true)

You can disable auto padding if the data has been encrypted without standard block padding to prevent
`decipher.final` from checking and removing it. Can only work if the input data's length is a multiple of the
