    [Mes] the private electronic printed document instructions

Ladies and gentlemen, dear friends and relatives:
    Moto Koji will tell you detail [Mes] private electronic printing document installation, use and technical key points, welcome to my shop.

    4 [Mes] Electronic Seal
    4.01 are briefly described below private documents issued by process:

    Private documents and digital signature operation, basically the same. What is different, its basic properties will be the original documents and the original documents, using a text encryption mode, edited into a fully independent accessories, can be a separate file, so it has very high security.Security communication of the electronic seal is mainly applicable to the network in.

    (1) please connect the z893 on the serial port, namely the seal of entity, and good working power supply.
    (2) different IP port z893, will be set to issue different printing.
    (3) the first run, the need for good serial port address and the serial baud rate.

    Using the mouse is key, double-click the icon, the kernel can correctly identify, is Windows XP or windows 7 operating system, and will be the main window of electronic seal, accurately placed in the lower right corner of the desktop.

    Using the mouse gently across the window, will find the three function keys, the upper left corner for the issuance of bonds, the upper right corner to receive keys, function keys middle parameter table.

    Using the mouse is key, click the parameter table of function keys, a pop-up window parameter table.

    Parameter table window top, two for edit, respectively, mark is "exercise" and "the authorization code".
    The following parameters table window, is the "export address" and "baud" two options.
    Used for the first time, must be in "port address" and "baud", fill in the correct parameters, and returns to "data confirm key".

    If you don't know IP baud rate of the port,
    Can be "baud" option, set to emdos,
    Click on the "data confirm key",
    The kernel will be in the IP port baud rate, anti read into pc,
    And will set up the registry parameters returned. (registry address for the c:\em\dat\ directory)

    Under normal circumstances, the need to re open again parameter list, check the baud rate value, Is it right? Best configuration in the PC within.
    If you need to modify this time "the baud rate",
    Can be "port address" option, set to emdos,
    Then the "baud" option, set the parameter value for what you need,
    Click on the "data confirm key",
    The kernel will again to the original IP port, the reverse of baud rate setting,
    And will set up the registry parameters returned. (registry address for the c:\em\dat\ directory)
    "The authorization code" and "right" unequal situation, electronic seal will refuse to issue the new seal, but the decoding function will be kept. This software allows the user to "Internet real name vote" vote, the rational use of pirated mode signature (vote function right ticket), the method is very simple, as long as with the left mouse button, double-click the authorization code edit window, software license code will remove the blank state, which has this shape signature under, will identified as "piracy piracy chapter, chapter" in the seal recognition, will be individually counted as one item. To restore the original pattern, shutdown after restart.
    The Internet real name vote, usually understood as: Signature agreed, against piracy as a function of endorsement, right.

    Using the mouse is key, click the issue of function keys, a pop-up will issue a window.

    Using the mouse gently across the window, will find that it has an "electronic printed issue of the start button" and two edit editor window. The top of a edit editor window, window is the input of the target file, which is filled with "C:\em\ stamp \00.txt", obviously, this is a default file name and path, which is used for user testing.
    The middle of a edit editor window, is a big input window, which is filled with "please input handling party message and effective date." Also, obviously, this is a place for users to fill out a memo.
    When the mouse fell in the target file header, will see the mouse pointer changes to a hand:
    [1] left click the target file header, will help you add a + the file name; right click the target file header, will help you reduce the a + the file name.
    [2] if the message file window is "empty", left click the target file, it will pop up a reminder: "are you sure you want to create 00.txt file, press yes, press no to exit!" ; prompt with two function keys: "Yes", "no". Using the mouse is key, click "yes". Will help you create a new file 00.txt, for testing.
    [3] Double click the file to the target edit window, a classical control keys will start windows, will help you in the PC file, with its correct path, fill in the window.
    When the mouse fell in the bottom left corner of the window digital display work area, will see the mouse pointer into a small:
    (1) under normal circumstances, the display data in the area should be 00, indicating the issued stamp is empty.
    (2) non normal conditions, the display data in the area should be 01-ff, indicating the issued stamp as busy.
    (3) when the seal for the busy, issuing software will refuse signature. If a system error, double-click the work area will make the data reduction to 00.

    Normal working process of electronic seal issued as follows:

    [1] please enter a valid file name [objectives] in the target document window.
    Edit support two input modes:
    1.1 direct input.
    1.2 the name of the file input.

    [2] please enter a valid [message] in the memo window.
    Edit support three input modes:
    2.1 direct input.
    2.2 indirect input.
    2.3 the name of the file input.

    [3] The input end of the parameters, the following can be signed.
    3.1 use the mouse is key, click the "start button electronic printing issue".
    Will pop up a reminder: "really want to use document [private] mode?" ;
    Tip with two function keys: "Yes", "no".

    3.2 use the mouse is key, click "yes".
    Then a pop-up hint: "the length of the file 4K[has 2 seals and 0 endorsement]";

    The tooltip also with two function keys: "Yes", "no".
    Careful users will find, became much a word: "issued memorandum below about seconds, confirm please wait!"
    This is the last tip, and then the mouse is key, click "yes", it is necessary to enter the formal signature program, can not be returned.
    3.3 use the mouse is key, click "yes".
    After 1 seconds, the seal was signed, this big window shows the following characters:

    The report shows (private editing qualified, and has successfully saved!), which means the current print is the perfect.

    Electronic printed document is very neat, it can be split into two parts and accessories of the stamp body.
    Electronic seal seal body, its size formats are similar, is composed of a few lines of digital character. A behavior codes, behavior code, alternately arranged, easy to recognize. The code for the code of the corresponding code, after decrypted to check on the Hamming code. This encryption method seems to be a big risk, is actually very safe. As with traditional encryption principle of the electronic seal completely different way, the key used for non regular dynamic key, namely each printing used in different keys for encryption, the text was obtained by the one-time key text.Allegedly has yet to find the effective method to solve this kind of ciphertext. In the dense field, usually think one-time key is unbreakable, I hope so!
    Appendix part of electronic seal is relatively large, it is not only reflected in length, but also in the type, there are great differences. Electronic printing accessories, followed by the date of issue, issue of file name, file attributes of issue. These categories look the same, but in fact each printed correlation length, difference is very big. Electronic seal is used in floating segmentation method, programming software technology is very difficult, of course, hackers have great difficulty, the security will be easy to get assurance.
    The middle part of electronic printing accessories for the user message. The message to support a variety of forms, in addition to the direct endorsement, can also use indirect way. The difference between the two is that the former is TXT text, and the latter is the name of a file.
    If the file name, electronic seal will be packaged into a whole file attachments, recorded in the electronic printing. When decoding will release in the c:\em\ directory. With electronic seal lock function, its accessories also has a lock function, non authorized to release, has very high security. Electronic printing support conjoined printing, so in theory can charge with multiple attachments, but the total length of a file, not more than 32 length file support system.

    With the mouse click is key, a function key is received, it will pop up a decoding window.

    Using the mouse gently across the window, will find that it has an "electronic printing decoding the start button" and two edit editor window.
    The decoding of electronic seal, is used in the traditional way, namely the decoding operation is issued operational anti operation, so the decoding window and issue of window are very similar, manipulation and functional operation are basically the same.

    [1] please enter a valid file name [objectives] in the target document window.
    Edit support two input modes:
    1.1 direct input.
    1.2 the name of the file input.

    [2] The input end of the parameters, the following can be decoded.
    2.1 use the mouse is key, click the "electronic printing decoding the start button".
    Will pop up a reminder: "really want to use document [private] mode?" ;

    Tip with two function keys: "Yes", "no".
    2.2 use the mouse is key, click "yes".
    Then a pop-up hint: "the length of the file 5K[has 1 seals and 0 endorsement]";

    The tooltip also with two function keys: "Yes", "no".
    Careful users will find, a word memo: "below about 1 second decoding, confirm please wait!"
    This is the last tip, and then the mouse is key, click "yes", it is necessary to enter the formal signature program, can not be returned.
    2.3 use the mouse is key, click "yes".
    After 1 seconds, the seal on the decoding well, then the big window shows the following characters:

    The report shows (private check qualified, and has successfully saved!), which means the current print is the perfect.

    A complete seal, should include: date of issue, issue the file name, length of time attribute, attribute, memo, version number, arithmetic logic identification code, identification code, zip code etc..
    Don't look down upon these figures about, each one is the killer, is linked together, there was an error will cause the entire seal check is not valid, and no longer issued, will also refuse to decode.
    The main part of the electronic seal is arranged in neat rows, the eight paragraph. Most of these paragraphs, can use the common reading tools visible, called Hamming code. There are some watch is at sixes and sevens character, called the password. Cipher codes corresponding code, using a non regular dynamic key, using the traditional method of encryption and become, its work mode similar to the one-time key work mode. PC can use z893 code conversion will be as plain language, used to seal check, security of the security based on the one-time key. Now the one-time key break, haven't found effective method, therefore, at least for now is still a very small risk.
    Z893 software is bundled with fixed together, control of z893 is equivalent to the control of the signature. As a hardware entity, its management and the way of use, can be completely analog seal habits and experience, can meet the general use of identity recognition.

    Welcome to my shop, thanks again for about!
