The translation of data into a secret code.
Encryption is the most effective way to achieve data security.
To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Some types of encryption are more secure than others. Using an encryption algorithm it is easy to produce cipher text from plain text, but very hard to reverse the process and get the original plain text back without the proper key. TDES is based on the long standing DES standard developed by IBM in 1978. This algorithm quickly became the US Government standard for data encryption.
