Deadwood and MaraDNS now have a Windows tool for making secret.txt

Deadwood and MaraDNS now both have a tool for getting entropy (random numbers) so that the file secret.txt is automatically generated. I call the tool "mkSecretTxt", and its source code can be looked at here:

http://samiam.org/software/mkSecretTxt.txt

Or downloaded as a C source file here:

http://samiam.org/software/mkSecretTxt.c

The file is a Windows port of the following *NIX command:

dd if=/dev/urandom of=secret.txt bs=64 count=1

In English: My program creates a 512-bit (64-byte) file called “secret.txt” using CryptGenRandom() to acquire the entropy from the Windows operating system.

This tool will make it easier for people to install and use MaraDNS and Deadwood in Windows, since they only have to run this program once to get some entropy for the servers’ random number generators.
