Cryptography is one of the most important areas in the computer industry. Encryption allows an application to secure its data from being accessed by hackers. Currently there are many industry-standard encryption/decryption algorithms including RSA, Rijndael, Blowfish [1,2], and so forth. However, they are fairly complex and require that one spend a lot of time to comprehend and implement them. This paper introduces two simple encryption/decryption algorithms that are fast and fairly secure. The algorithms manipulate a 64-bit input using flipping, mapping, and shifting to achieve its encryption/decryption.
