KeySize

Property KeySize as Integer

This property defines the key size that applied to symmetric encryption in bits. This keys does not affect RSA or AES encryption/decryption functions, they have their own ways of defining the size of the key. This is not a length of the password, it's a length of the key that created internally based upon the password.

Default value is 128, that means that 128 bit key will be created and used for encryption/decryption procedures. For example VISA cardholder requirements demands TrippleDES encryption with minimum 768 bit key. This means that before using TrippleDES encryptionyou should set this property to 768.
