Description copied from interface: Cipher

Performs in-place encryption or decryption on the given data.

Specified by:

update in interface Cipher

Overrides:

update in class BaseCipher

Parameters:

input - The input/output bytes

inputOffset - The offset of the data in the data buffer

inputLen - The number of bytes to update, starting at the given offset; must be a multiple of the cipher's block size

Throws:

Exception - If failed to execute
