Detailed Description
Container for keys for symmetric encryption algorithms.
- Examples
- aes-cmac.cpp, ciphertest.cpp, and mactest.cpp.
Constructor & Destructor Documentation
◆ SymmetricKey() [1/4]
| QCA::SymmetricKey::SymmetricKey | ( | ) |
Construct an empty (zero length) key.
◆ SymmetricKey() [2/4]
| QCA::SymmetricKey::SymmetricKey | ( | int | size | ) |
Construct an key of specified size, with random contents.
This is intended to be used as a random session key.
- Parameters
-
size the number of bytes for the key
References QCA::SecureArray::size().
◆ SymmetricKey() [3/4]
| QCA::SymmetricKey::SymmetricKey | ( | const SecureArray & | a | ) |
Construct a key from a provided byte array.
- Parameters
-
a the byte array to copy
References QCA::SecureArray::SecureArray().
◆ SymmetricKey() [4/4]
| QCA::SymmetricKey::SymmetricKey | ( | const QByteArray & | a | ) |
Construct a key from a provided byte array.
- Parameters
-
a the byte array to copy
Member Function Documentation
◆ isWeakDESKey()
| bool QCA::SymmetricKey::isWeakDESKey | ( | ) |
Test for weak DES keys.
- Returns
- true if the key is a weak key for DES
