Member Function Documentation
◆ BlockSize()
template<class T_HashWordType , class T_Endianness , unsigned int T_BlockSize, class T_Base = HashTransformation>
|
inlinevirtual |
Provides the block size of the hash.
- Returns
- the block size of the hash, in bytes
BlockSize() returns T_BlockSize.
Reimplemented from HashTransformation.
Definition at line 141 of file iterhash.h.
◆ GetByteOrder()
template<class T_HashWordType , class T_Endianness , unsigned int T_BlockSize, class T_Base = HashTransformation>
|
inlinevirtual |
Provides the byte order of the hash.
- Returns
- the byte order of the hash as an enumeration
GetByteOrder() returns T_Endianness::ToEnum().
- See also
- ByteOrder()
Implements IteratedHashBase< T_HashWordType, HashTransformation >.
Definition at line 147 of file iterhash.h.
◆ CorrectEndianess()
template<class T_HashWordType , class T_Endianness , unsigned int T_BlockSize, class T_Base = HashTransformation>
|
inline |
Adjusts the byte ordering of the hash.
- Parameters
-
out the output buffer in the input buffer byteCount the size of the buffers, in bytes
CorrectEndianess() calls ConditionalByteReverse() using T_Endianness.
