| I was wondering where I can find a snippet where you can encrypt/decrypt a binary file using XOR? I found only the example and do you think this is good enough? http://www.blitzbasic.com/b3ddocs/command.php?name=Xor |

;Simple xor encryption with crappy key
;swap the input and output files to see it in action...(decryption is encrpytion in reverse)
seedrnd 1 ;this is your key...(actually the key is the same length as the file and is determined as a random sequence by this seed)
infile = readfile("yourinputfile.txt")
outfile = writefile("youroutputfile.txt")
while(not(eof(infile)))
writebyte outfile,readbyte(infile) xor rand(0,255)
wend
closefile outfile
closefile infile
end
