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.
