Create New Archive File

To get your data encrypted and compressed into a single archive file, you should create new archive file where the data will be stored. As soon as you create new archive, you can add regular files and folders to the archive.

There are the following ways to create new archive file:

1. In My Computer window open the folder where you want to create new archive file. In the File menu of the My Computer program run New -> Jetico BestCrypt Archive command.
2. Run BCArchive program from the Start -> Programs -> BCArchive program folder. Then in the BCArchive main window run New command from Archive menu.
3. Right-click on a file/folder in My Computer window and run the command Add to "file_name.bca"

If you want your new archive to be accessed by entering some password, just enter the password twice in the Password and Confirm password edit boxes and click OK. Then BCArchive will ask you to make random movements by mouse to generate unique encryption key and the process of creating the archive file will be finished.

The process of creating a new archive can also be more creative work. If you decide to make new archive encrypted by some public key, or you wish to select some concrete encryption options, click Advanced . The BCArchive dialog window will start looking like:

Since Password based encryption radio button is selected, you continue creating new archive that will be possible to open with a password, but now you can change a number of encryption settings for the archive file:

• Encryption algorithm used to encrypt data inside the archive (Triple-DES in our example);
• Encryption algorithm used to encrypt randomly generated key for the archive (Blowfish in our example);
• Secure hash algorithm for the process of deriving intermediate encryption key from the password (SHA-1 in the example);
• Salt (random data) and Iterations parameters are used exactly as it is required by PKCS #5 specification (recommendations for the implementation of password-based cryptography).

If you wish to create new archive so that it will be decrypted by secret key of some user, you should encrypt the data by corresponding public key of the user. Hence, you should select the Public key encryption radio button as it is shown below:

After that you only need to select public key of the user (probably yourself). You can take the public keys from two places:

1. Find the public key in your Local Key Database (click Browse button).
2. Find the public key in Internet (click Net search ).
