Expand description

AES-CBC decrypt initialization.

The context * ctx - is initialized using the given key * key - and initial vector * iv - .

ctx - Context.
key - AES key. May be NULL.
size - Key size (16, 24, or 32 bytes).
iv - Initial vector. May be NULL.

@remark If * key - is NULL only * iv - is set. If * iv - is NULL only * key - is set. Both * key - and * iv - must be set before update is called.
