Only the adapter 510 users can use encryption/decryption provided by the wireless encryption-hub 512.

(61) In FIG. 6 is shown an encryption box 610 plugged into a device such as a PC 602. Once the encryption box 610 is plugged into a device such as a PC 602, a number of applications can be downloaded and installed automatically or manually.

(62) In one embodiment, ppExcel, which integrates Microsoft Excel and the encryption box 610, is fully embedded inside MS Excel to provide encryption/decryption on MS Excel cells regardless of cells' type.

(63) It is well known that the complications of cells format of MS Excel such as number cells, text cells, and formula cells forming a major difficulty for any encryption engine to provide security encryption successfully. These different cell types are not compatible each other, but are inter-related. When changing one type of cells such as formula cells with encryption, all other dependent cells such as number cells will changed to difficult status immediately. For this reason, it is believed that no traditional encryption engine can provide encryption successfully on Excel cells regardless of its types. With a digitizer and clipboard module, the encryption box 610 can provide a solution to this problem.

(64) Once the encryption box 610 is plugged into a device such as a PC 602, the encryption box 610 will install a clickable tag 702 called “ppExcel30”, as shown in FIG. 7. When this ppExcel30 tag is clicked, a series of functional buttons 704 will appear onto the MS Excel software.

(65) The functional buttons 704 provided by ppExcel can be used for encryption and decryption on selected cells, entire sheet, and the whole workbook of Excel regardless of the cell types. It is believed that ppExcel is the first encrypter to provide cells encryption for MS Excel successfully in this style.

(66) The following process describes the basic encryption of ppExcel on MS Excel cells:

(67) 1. Highlight the selected original cells in Excel that you want to encrypt,

(68) 2. Press the “Enc/Dec Selected Cells” button,

(69) 3. ppExcel will copy all selected cells and send them to the Encryption-Box one-by-one,

(70) 4. After the encryption by the Encryption-Box, the cell contents will be sent to clipboard,

(71) 5. ppExcel will then paste the encrypted cell contents on clipboard back to its former cell location.

(72) The following process describes the basic decryption of ppExcel on MS Excel cells with respect to FIG. 7:

(73) 1. Highlight the selected encrypted cells in MS Excel that you want to decrypt,

(74) 2. Press the “Enc/Dec Selected Cells” button,

(75) 3. ppExcel will copy all selected encrypted cells and send them to the Encryption-Box one-by-one. Since they are ppExcel encrypted (in Digitized Cipher text Stream format), Encryption-Box will perform decryption automatically,

(76) 4. After the decryption by the Encryption-Box, the original cell will be sent to clipboard,

(77) 5. ppExcel will then paste the cell on clipboard back to its former cell location.

(78) A process of encrypting the MS Excel cells with ppExcel is shown in FIGS. 8 and 9.

(79) 1. First mark (or highlight) the cells that you want to encrypt 802 from MS Excel,

(80) 2. Click the “Enc/Dec Selected Cells” button 904,

(81) 3. The selected original cells of MS Excel 802 will be replaced by the encrypted cells 902.

(82) By using the similar construction, the following associated prototypes are also established:

(83) 1. ppOutlook, which integrates MS Outlook and the Encryption-Box.

(84) 2. ppWord, which integrates MS Word and the Encryption-Box.

(85) 3. ppPowerPoint, which integrates MS PowerPoint and the Encryption-Box.

(86) In another embodiment, shown in FIGS. 10 and 11, PPM, which is a Universal Text Encrypter using the encryption box 1004, can use the encryption box 1004 for any text encryption/decryption from any other programs.

(87) Due to the complications of all different programs in different platforms (or operating systems) that produce texts, it is not easy for traditional encryption engines to construct a universal encrypter that can encrypt/decrypt texts for all of them. With the digitizer and clipboard modules, the encryption-box 1004 establishes a universal encrypter called PPM (Professional Protection for Messages) to encrypt/decrypt any text from any other programs.

(88) Once the encryption box 1004 is plugged into a machine 1002, as shown in FIG. 10, the encryption box 1004 will download and install a program called “PPM” 1102, which is shown in FIG. 11. PPM 1102 is a universal text encrypter for any text related program. Any text change in the Original Message window will trigger automatic encryption and the encryption results will appear in the Encrypted Message window. Any text change on the Encrypted Message window will trigger auto-decryption and the decryption results will appear on the Original Message window.

(89) The buttons provided by PPM can be used for encryption and decryption on any text from any program. When you type a piece of text into the Original Message window, it will be encrypted automatically and the encrypted message will appear in the Encrypted Message window.

(90) Among the buttons may be:

(91) Msg Copy—Copy the text in the Original Message window onto the Clipboard,

(93) Enc Copy—Copy the encrypted text from the Encrypted Message window onto the Clipboard

(94) Enc Paste—Download the encrypted text from the Clipboard into the EncryptedMessage window. The encrypted text will be decrypted automatically and appear in the Original Message window. This may also be referred to as Auto-Decrypt.

(95) The encryption process of PPM will be described with respect to FIGS. 12 and 13:

(96) 1. Hightlight and press the Control-C key on selected text 1202 such as “This is my secret” from any text related program (This will send the selected text to Clipboard)

(97) 2. Press the “Msg Paste” button of PPM

(98) (The PPM will copy the text from the Clipboard and paste to the Original Message window)

(99) 3. The text in the Original Message window 1302 will be encrypted automatically and immediately

(100) 4. The encrypted text will appear in the Encrypted Message window 1304 as

(101) “f3 0e c2 ab e2 ef 71 4a e1 70 67 81 53 95 28 02 12 e1 5a cf 5a 3b 27 cf 73 90 93 68 df 3a 74 f5 5c f4 ff c2 6c 14 dc fd”

(102) paired hexadecimal numbers with space (or digitizing mode=3).

(103) The decryption of PPM will be described with respect to FIGS. 14 and 15:

(104) 1. Hightlight and press the Control-C key on any PPM encrypted text 1402, this will send the selected text to the clipboard,

(105) 2. Press the “Enc Paste” button of PPM, the PPM will paste text from Clipboard to the Encrypted Message window 1504,

(132) In a fourth embodiment, shown in FIG. 21, a method of secure encryption using an encryption box device includes a first operation 2102 of plugging the encryption box device into a computer. The method of secure encryption then performs a second operation 2104 of running an application on the computer. The method of secure encryption then performs a third operation 2106 of downloading a plaintext stream from the application to a first clipboard. The method of secure encryption then performs a fourth operation 2108 of encrypting the plaintext stream to produce an encrypted stream. The method of secure encryption then performs a fifth operation 2110 of digitizing the encrypted stream to produce a digitized encrypted stream. The method of secure encryption then performs a sixth operation 2112 of uploading the digitized encrypted stream to a second clipboard.

(133) The application may be a spreadsheet, a text window, an email, a word processor, a chat room, or a presentation.

(134) The method of secure encryption may further include a seventh operation of digitizing the encrypted stream according to a mode such as no digitization, Base 64 digitization, hexadecimal numbers without spacing, paired hexadecimal numbers with spacing, a user-defined mode, or save as a file (flag).

(135) The method of secure encryption may further include an eighth operation of downloading the digitized encryption stream from the second clipboard. The method of secure encryption may further include a ninth operation of de-digitizing the digitized encryption stream to produce the encrypted stream and providing the encrypted stream to the encryption engine. The method of secure encryption may further include a 10.sup.th operation of decrypting the encrypted stream to produce the plaintext stream and uploading the plaintext stream to the first clipboard.

(136) The method of secure encryption may further include an 11.sup.th operation of de-digitizing the digitized encryption stream according to a mode such as no de-digitization, Base 64, hexadecimal numbers without spacing, paired hexadecimal numbers with spacing, a user-defined mode, or save as a file (flag).
