Detailed Description
template<typename T>
class XTSSingleKey< T >
Implementation of the single-key XTS mode for 128-bit block ciphers.
XTS mode normally uses two keys to encrypt plaintext and the sector-specific tweak values. This class uses the same key for both purposes, which can help save memory.

Constructor & Destructor Documentation
◆ XTSSingleKey()
template<typename T >
|
inline |
Constructs an object for encrypting sectors in XTS mode with a single key instead of two split keys.
This constructor should be followed by a call to setSectorSize(). The default sector size is 512 bytes.
The documentation for this class was generated from the following files:
