Encrypt Files using 256 bit Block Cipher : Rijndael for the highest possible data security.
Rijndael is approved as the Advanced Encryption Standard, FIPS-197 by NIST
This standard specifies Rijndael as a FIPS-approved symmetric encryption algorithm that may be used by U.S. Government organizations (and others) to protect sensitive information.

PROCEDURE:
File Encryption:
------------------------
1) Browse and select a file by pressing the Browse button.
2) Type a password in the password field.
- The password should be at least 6-10 digits long. And should both alphabets (a-z ; A-Z)
and numbers(0-9) and preferably symbols.
- It should be easy to remember but difficult for others to guess.
- There are no restrictions on password length as an irreversible Hash is generated from
the password.
3) Retype the password.
4) Select the file naming (leave it to modify: recommended).
5) Press the Encrypt (Red) Button
File Decryption:
----------------------
1) Browse and select the encrypted file pressing the Browse button.
2) Type the password in the password field.
3) Retype the password.
4) Select the file naming (leave it to modify: recommended).
5) Press the Decrypt (Green) Button
Naming Convention:
------------------------------ - -
The files are renamed as follows:
In Append Mode:
.encr or .decr is appended to the filename, for each Encryption or Decryption process.
In Rename Mode:
1) For Encryption: .encr is appended to the filename.
2) For Decryption: All .encr and .decr extensions are removed and original filename
restored with .decr appended in between.
For Example: A file abc.txt.encr will be renamed abc.decr.txt
