File Encrypter (FIPS-197) - Arpan Jati - ArpanTECH --------------------------------------------------------------------------------

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.

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.

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 Algorithm:Uses 256bit cipher Rijndael (FIPS-197) Arpan Jati - ArpanTECH, Inc All Rights Reserved
