Random Number (256 bits)

This will generate a cryptographically secure random 256-bit number (using this function).

However, the problem you've got is I could easily save each number you generate before I print it to this page. I can tell you that I'm not doing this, but there is no way for you to know for sure.

Hey there, it's Greg.

I'll let you know about cool website updates, or if something seriously interesting happens in bitcoin.


Don't worry, it doesn't happen very often.
