- indigo945 5y agoSolitaire is very broken as an encryption scheme. You should not use it for communication that requires more than LARP security. If you need to encrypt a message manually, LC4 is a better algorithm, but still not acceptable for real world use. The good old one time pad may be most effective.
- ixwt 5y agoI don't remember reading it was broken per say, just that there are some issues, and weak keys. The only work I know of analyzing Solitare is [0]. And they propose some fixes to make it more resilient. OTP is by far the easiest and most reliable pencil and paper crypto algorithm though.
