The application of technological and related procedures to safeguard the security of various documents while moving on the channel is an important responsibility in electronic data systems. This paper specifies the modification of the Data Encryption Standard (DES) and the Triple Data Encryption Algorithm (TDEA) which may organizations to protect sensitive data. Protection of data during transmission or while in storage may be necessary to maintain the confidentiality and integrity of the information represented by the data. The algorithms uniquely define the mathematical steps required to transform data into a cryptographic cipher and also to transform the cipher back to the original form.
