Encryption is the effective way to provide the needs of security and privacy. The performance of any encryption algorithm is one of the most important parameters if not the most one in encrypting data. Also, random access memory utilization plays an excellent role in ciphering plain texts. Speaking of standard simple encryption algorithms that most of them are weak and may not be safe to use them to cipher our data communication from any threat such as Caesar algorithm [2].However, they have good results in the parameters. Nevertheless, merging these simple algorithms could generate a more powerful algorithm that takes a very long time and excessive efforts to break it. Both standard algorithms “Vernam Cipher” and “Rail-Fence stream” merged to produce the “Railve” algorithm, which has great performance and consumes a small amount of RAM. The three algorithms are applied on two devices “a mobile phone and a laptop”
