CG FileCryptTM   

(under Development)

This application Encrypts and Decrypts files by using the ComputerSafe Security System core encryption algorithms.  It's main purpose is to allow a user a reliable way of transporting files encrypted with the ComputerSafeTM Security System to another location and then to decrypt them for use without requiring the installation of the entire ComputerSafe program.  When done, the user may re-encrypt those files using the same private key or a new key.

This program can be used with any fixed or portable storage media (i.e.. flash cards, USB memory sticks, hard drives, CD's).

Important Note:  After clicking Download please select the save option and store the program to your desired folder then double click on "CGFileCrypt.exe" to start the program.

 

Basic Usage - This program performs very fast encryption and decryption of files. It utilizes the robust American Encryption Standard algorithm (the same that is used in the ComputerSafe product).

 

Encrypting Files -

1.  Highlight folders/files in the tree window that you wish to encrypt using the methods below.

  • Select Single Item - left click the item.

  • Select consecutive files/folders - click the first item, press and hold down SHIFT, and then click the last item.

  • Select nonconsecutive files/folders - press and hold down CTRL and then click each item.

2.  Press the Encrypt button and you will be prompted for a key (series of characters) to use for the process.

 

Important Note:  Do NOT forget this key as you will not be able to decrypt the file without it!!!

 

3.  A status window will appear showing the progress of the encryption process.  Press the "close status window" button when the "Finished..." text appears.

Note:  If you select files or folders that are already ComputerSafe encrypted, you will first be prompted for a new key and then prompted again to enter the old key (used to previously encrypt) the files/folders.  Example:  If you had previously encrypted abc.txt using a key of "janedoe" and you selected that file to encrypt, you would (at the first prompt) enter the new key you want to use for the file (i.e.. "johnsmith" and then at the second prompt you would have to enter "janedoe".  This is to insure that you are in control of the file and do know the old key before the program decrypts it and then re-encrypts it.

Decrypting Files -

1.  Highlight folders/files in the tree window that you wish to decrypt using the methods below.

  • Select Single Item - left click the item.

  • Select consecutive files/folders - click the first item, press and hold down SHIFT, and then click the last item.

  • Select nonconsecutive files/folders - press and hold down CTRL and then click each item.

2.  Press the DeCrypt button and you will be prompted for a key (series of characters) to use for the process.

 

3.  A status window will appear showing the progress of the decryption process.  Press the "close status window" button when the "Finished..." text appears.

Note:  If you have selected multiple items to decrypt and those files were encrypted with different keys, you will be periodically prompted during the decryption process for the encryption key for file(s).  Example:  You encrypted a.txt with "tom", you encrypted b.txt with "jane".  Now later you selected both files to decrypt.  You would be prompted for a key for a.txt and also prompted for b.txt.  This is due to them having different encryption keys.  However if you selected say 20 files to decrypt and the first 10 had the same key as each other and the last 10 had the same key as each other, then you would only be prompted two times for a key.
