Member Function Documentation
◆ GetAlignment()
template<typename WT , unsigned int W, class BASE = CFB_CipherAbstractPolicy>
|
inline |
Provides data alignment requirements.
- Returns
- data alignment requirements, in bytes
Internally, the default implementation returns 1. If the stream cipher is implemented using an SSE2 ASM or intrinsics, then the value returned is usually 16.
Definition at line 472 of file strciphr.h.
◆ GetBytesPerIteration()
template<typename WT , unsigned int W, class BASE = CFB_CipherAbstractPolicy>
|
inline |
Provides number of bytes operated upon during an iteration.
- Returns
- bytes operated upon during an iteration, in bytes
- See also
- GetOptimalBlockSize()
Definition at line 477 of file strciphr.h.
◆ CanIterate()
template<typename WT , unsigned int W, class BASE = CFB_CipherAbstractPolicy>
|
inline |
Flag indicating iteration support.
- Returns
- true if the cipher supports iteration, false otherwise
