The source is available to you, go and check

It's as strong as your entropy. If you decide to be lazy about rolling dice and enter the pattern 111111... for the dice rolls, not so secure. If you use your system's entropy pool, more so.

Also, compiling it works for me (with basic build environment). What distro/compiler are you using, nd what issues are you having?

This is a beautiful master piece but it seems it is not working on Linux yet, also how safe is the fund stored in the account.

In the easiest setup, the bitgen software can generate random numbers by using the /dev/random generator.

To use this method, just give the following command:
./bitgen random

This will give you ps-files with the private key and public address (as well as text files with the same information).

However, it is also possible to generate a random number manually, and give that to bitgen.
If you throw a 6-sided dice 100 times, this will give you 256 bits of entropy, which is used to calculate the private key.

Throwing a single dice 100 times is a bit tedious, but if you throw 10 dice 10 times, this is actually quickly done.

Why not letting /dev/random generate the random number then?

Subverting random number generation is a wet dream of espionage agencies.
/dev/random is probably generating good random numbers, but you never know....
The NSA may know some weakness in the default random number generator.

For large amounts of money, throwing the 10 dice yourself will make you sleep well at night.

The algorithm in bitgen for converting from a base-6 number to a base 2 number is very simple,
and the source code is provided so anyone can verify the calculation.

For example, the following bitgen command will generate a bitcoin private key from 100 dice throws:

./bitgen dice 5123512351523523525525252552531523515235123512531523512355525253566616166262661 662626626363663636363

Can you explain more the details about this project? Where the address come? It's mean from the wallet? How to manage the address?

Bitgen is a command line tool for bitcoin addresses and transactions.

This is the project home page:
http://bitgen.org/

Bitgen can generate bitcoin addresses in different ways and supports generating postscript files with the generated addresses.
Bitgen can also do many other bitcoin related tasks, such as decoding bitcoin transactions and scripts.
