//This sample code tests the VAE Rest calls to the Vormetric Crypto Server.
//It will first encrypt a file and create an output file with enc at the end of it.
//You can then select the file that you just encrypted that ends with an enc and
//the application will then decrypt it.
//The input file format should be a single entry for each line.
//This is for testing only so it will only at most process the first 10 records
//in the file.
