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

SymmetricKey() [3/4]

QCA::SymmetricKey::SymmetricKey

(

const SecureArray &

a

)

Construct a key from a provided byte array.

Parameters

a	the byte array to copy

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
