Conceal

Conceal would analyze the file type and upon acceptance it prompts you to choose your destination path- where the encrypted file will be saved and to enter your password to encrypt the file. Here youll be given some additional options like- wether, after encryption, you want to keep your original file or not.
Conceal provides a set of options to the user while encrypting the file. You can select the algorithm for encrypting your file as per you personal /organizational needs. A brief account for each of these algorithms is written to give user a basic idea of the differences in using these specific algorithms.
Its indicated in terms of overall data security and time of execution of the algorithm.This will assist you in making a correct choice.When you havent selected any of the options, then Conceal chooses a default algorithm for Encryption, which is the Data Encryption Standard(DES).
Amongst the four indicated options for encryption, Conceal also offers its custom algorithm for encryption, called the "Fast Encrypt".This will be useful if "High speed" is preffered above "High security".
From security perspective, Fast Encrypt works well in case of all binary files except those which notepad compatible.Another distinctive aspect of Fast Encrypt is that it will take a constant amount of time while encrypting files ranging from a few KBs to as large as in GBSystem requirements256MB RAM
