64B3AC - SYmmetric Crypto-system for Business Using the ASCII Alphabet and Algorithm Codes Called in Cascade

The paper introduces a cryptographic technique useful to encipher the content of private business reports and a corresponding prototype called 64B3AC (SYmmetric Crypto-System for Business using the ASCII Alphabet and Algorithm Codes Called in Cascade), developed and tested under a data oriented environment. References to a special interactive tutorial presenting the logic and functionality of this technique are also included. Historical elements starting from initial ideas, challenges and applications up to potential improvements of the current version were considered too. In order to offer an honest image concerning the performance of this technique the paper includes the results of two hundred successful tests focused on processing speed, input and output as occupied space and number of total files generated or used along the encryption or decryption processes (one hundred for each way). Another goal of the paper was to underline the possibilities of the symmetric encryption with many advantages when mixed with other techniques
