General superclass for key derivation algorithms.
KeyDerivationFunction is a superclass for the various key derivation function algorithms within QCA. You should not need to use it directly unless you are adding another key derivation capability to QCA - you should be using a sub-class. PBKDF2 using SHA1 is recommended for new applications.
| QCA::KeyDerivationFunction::KeyDerivationFunction | ( | const KeyDerivationFunction & | from | ) |
Standard copy constructor.
| from | the KeyDerivationFunction to copy from |
|
protected |
Special constructor for subclass initialisation.
| type | the algorithm to create |
| provider | the name of the provider to create the key derivation function in. |
| KeyDerivationFunction& QCA::KeyDerivationFunction::operator= | ( | const KeyDerivationFunction & | from | ) |
Assignment operator.
Copies the state (including key) from one KeyDerivationFunction to another
| from | the KeyDerivationFunction to assign from |
| SymmetricKey QCA::KeyDerivationFunction::makeKey | ( | const SecureArray & | secret, |
| const InitializationVector & | salt, | ||
| unsigned int | keyLength, | ||
| unsigned int | iterationCount | ||
| ) |
Generate the key from a specified secret and salt value.
| secret | the secret (password or passphrase) |
| salt | the salt to use |
| keyLength | the length of key to return |
| iterationCount | the number of iterations to perform |
| SymmetricKey QCA::KeyDerivationFunction::makeKey | ( | const SecureArray & | secret, |
| const InitializationVector & | salt, | ||
| unsigned int | keyLength, | ||
| int | msecInterval, | ||
| unsigned int * | iterationCount | ||
| ) |
Generate the key from a specified secret and salt value.
| secret | the secret (password or passphrase) |
| salt | the salt to use |
| keyLength | the length of key to return |
| msecInterval | the maximum time to compute the key, in milliseconds |
| iterationCount | a pointer to store the number of iteration done for the specified time |
|
static |
Construct the name of the algorithm.
You can use this to build a standard name string. You probably only need this method if you are creating a new subclass.
| kdfType | the type of key derivation function |
| algType | the name of the algorithm to use with the key derivation function |
