Encrypt Object

Click on "Encrypt Object" button, a dialogue box will come up with the options: "Enable file compression" and "Encryption algorithms". (See Figure 1)

"Enable file compression" makes an encrypted file smaller. Moreover, this compression algorithm is different from that of the popular compression tools such as "Winzip" and "Winrar". It increases the encryption intensity in certain degree, but sacrifices some speed. You may choose by yourself.

Encryption algorithms: You can choose the most advanced encryption algorithms such as AES256, DES, 3DES and Blowfish, etc. We recommend AES256 (The Advanced Encryption Standard), which is the norm of encrypting electronic data used by American National Standard and Technological Research Institute.

Then a password input box will come up (see Figure 2) you can choose to type in a password directly, or you can use an authorized disk or a file as password. If you type in the password directly, it should be at least 6 digits long for the security concern. If you use an authorized disk or a file as password, the length of the password can be between 0 to 128 digits. That is, to encrypt files you can just use an authorization source (a disk, CD or file) instead of a password, and this is a good choice if you have a bad memory.

If you choose "Use authorized disk" option, you can select a floppy disk, a flash disk, a hard disk or a CD-ROM as the authorized disk. However, we suggest not using a hard disk since it is easy to guess; If you use a floppy disk, it would be a good idea to back up or copy it with tools such as HD-COPY or DISKCOPY because floppy disks may easily become unusable and these tools can maintain an exact copy of the original one. You can read, write, add or delete files on the floppy, flash, or hard disk, but DO NOT format them! That is equal to losing your password! Furthermore, the pre-formatted floppy disks can not be used as an authorized disk and you need to format them again by yourself. Compared to a floppy disk, a CD-ROM is not so easily damaged and it is the best choice for an authorized disk. But you need to notice that the same CD-ROMs manufactured in the same group have the SAME authorization effect. One authorized disk has the same authorization effect on Windows XP/2000/2003/NT, but differs from the effect on Windows 98. If you choose a file as your password, any file on a floppy, hard or CD-ROM can be used, but remember to backup the file and DO NOT change its name! Moreover, DO NOT encrypt the password file! Otherwise your files or folders encrypted by the password file will never be decrypted!

To use an encrypted file, you need not decrypt it with SuperEncryptor. After double-clicking the file, a password input box will come up. The file will be opened after putting in the correct password. With a wrong password, it will exit. After you open the file, you can edit and save it. After you close the file, it is still in encrypted state, there is no need to encrypt it again. After files are encrypted, their icons will be changed into a lock, but the icons of the common used files (such as txt, doc, xls, ppt, gif, jpg and bmp, etc.) will not be changed.
