If more than one RNG is selected, their output will be combined (XOR'd together) and the resulting data used. In this way, the random data generated will never be weaker than the strongest selected RNG.
Microsoft CryptoAPI
The Microsoft CryptoAPI is used to generate random data.
Mouse Movement
This relies on the user "waggling" the mouse in a random fashion to generate random data.
Every 100ms the mouse pointer is checked. If it has moved significantly, then the X and Y coordinates of the mouse pointer are sampled, and the LSB of each is added to the random data collected.
Due to the volume of random data required, and the fact that only 2
bits of random data are collected for each mouse position sampled, this
is a relatively slow process.
cryptlib
cryptlib is used to generate random data.
Note: This option is only available if cryptlib (cl32.dll) is installed; see the cryptlib WWW site for further details and download.
PKCS#11 Tokens
If you have a security token or smartcard, this may be used as a RNG.
See the Security Token/Smartcard Support section for more information on setting up and using PKCS#11 tokens.
