Catastrophic Planetary Encryptor is a little donation from us to those who would like\n            to avail full privacy and safety of data that is transferred from them to another trusted\n            user. Many applications have built in Encryptors and Decryptors that\n           do a pretty honest job in protecting data. But there are always algorithms and minds behind these ever evolving\n           algorithms, that eventually find a way to reverse vital information through loopholes by disecting\n           the source code.\n\n           It is for this reason that an offline encryptor needs to be available that is fast, reliable, easy to use and\n          most importantly independent from the programe being used to sent important data.\n           This is because even if your encrypted message does get deciphered, it will still make no sense as you would have typed\n          in an already encrypted message using CPE that is Catistrophic Planetry Encryptor, which too works on different ciphers, thus to make our programme even better\n          and to make sure our CPE community keeps growing, do give us full weightage\n           so we can keep improving.\n\n\n\n           Dear user, you are welcome to use version 0.0.57.2 which is fully available free of cost.
