Here is a small program I made for shits and gigs. It will take an input string and either encrypt it or decrypt it by the given matrix. This is done by first converting the input string to its ascii number, then using it in matrix multiplication before converting the new number to unicode. So "Hello there programmers
" becomes ŷΛưиÃÈÆ¬Ð´Æ»ÑÃ…ÈdžѮƤОƕϽƴтƻÑÓȹĆʊ with the default matrix 1,3,3,7. To decrypt the message ŷΛưиÃÈÆ¬Ð´Æ»ÑÃ…ÈdžѮƤОƕϽƴтƻÑÓȹĆʊ, put it in the input box and press decrypt.
