Word Search library

Ang Glasswall Embedded Engine ay nagbibigay ng malalim na inspeksiyon ng file, remediation, sanitisation, at pag-uulat. Dinidekonstrak ng engine ang isang file sa mga estruktural nitong bahagi at bumubuo ng panloob na mala-punong representasyon ng file. Sinusuri nito ang bawat node ng puno, iniinspeksiyon, inaayos, at sini-sanitise ang mga item ng nilalaman bago muling buuin ang isang bagong file.

Nagbibigay rin ang Glasswall Embedded Engine ng kakayahang mag-export at mag-import ng internal representation ng engine ng isang file structure sa isang intermediate format gaya ng XML. Dahil dito, maaaring gawing available sa mga external program ang mga internal component ng isang file para sa karagdagang pagproseso, bago muling buuin ang file upang maisama ang mga externally modified na component na iyon.

Ang Glasswall Word Search engine ay binuo sa ibabaw ng kakayahan sa export at import, at nagsasagawa ng paghahanap ng teksto sa content at metadata ng isang file. Ang mga search string, content management, at mga rule sa redaction ay kino-configure sa pamamagitan ng isang XML file. Ginagamit ang isang user-configurable na character substitution map na tinukoy sa JSON form upang magbigay ng suporta para sa text obfuscation. May kasama ring built-in na suporta ang engine para sa regular expression.

Configuration ng Word Search​

Tinutukoy ng configuration ng Word Search ang tekstong hahanapin, o ang regular expression na ilalapat, at kung paano ito dapat tratuhin kapag nakita sa loob ng dokumento. Ang configuration ng Word Search ay isang extension ng Glasswall content management.

Mga halimbawang policy file at schema​

Ang mga halimbawang Word Search policy file at homoglyph dictionary ay makikita sa folder na /configs/sdk_word_search ng release package. Ang Word Search XSD ay makikita sa folder na /schemas/sdk_word_search ng release package.

Halimbawang configuration policy​

Mga setting ng teksto​

Ipinapakita ng mga sumusunod na seksyon ang iba't ibang textSetting na maaaring tukuyin sa isang configuration policy. Para sa higit pang impormasyon tungkol sa iba't ibang setting, sumangguni sa pahinang Word Search & Redaction.

<textSearchConfig libVersion="core2">
    <textList>
        <textItem>
            <regex>((25[0-5]|(2[0-4]|1\d|[1-9]|)\d)\.?\b){4}</regex>
            <textSetting>require</textSetting>
        </textItem>
    </textList>
</textSearchConfig>

Konpigurasyon ng system​

Tulad ng sa core Glasswall engine, ang mga karagdagang switch ay makikita sa ilalim ng seksyong sysConfig. Kinokontrol ng mga ito ang asal ng Word Search engine habang pinoproseso ang mga input file.

<sysConfig>
    <!--interchange_type must always be specified with the value "xml"-->
    <interchange_type>xml</interchange_type>
    <!--Enables/disables processing of text files. False by default.-->
    <enable_text_support>false</enable_text_support>
</sysConfig>

Mga kilalang limitasyon​

• Hindi posible ang sabay na pagproseso ng parehong Office at text files
• Kapag nagpoproseso ng mga text file, kailangang may nakatakdang kahit isang require policy
• Ang interchange_type ay dapat palaging tukuyin bilang xml sa ilalim ng sysConfig
• Configuration policy that has a combination of the following textSettings with the same text/regex defined will always process the file:
  • require at redact
  • require at disallow
  • redact at allow
  • allow at disallow

Halimbawang JSON homoglyph config​

Pinapayagan ng JSON file ang user na gumawa ng pagmamapa sa pagitan ng mga character at ng katumbas na mga homoglyph. Pinapayagan nito ang engine na isaalang-alang ang mga homoglyph kapag bumubuo ng mga search expression, na nagbibigay ng suporta para sa mga homograph (magkakamukhang mga salita) at obfuscated na teksto.

Halimbawang analysis report​

Narito ang isang halimbawang analysis report na nabubuo kapag ang search string ay nakatakda sa 'Glasswall', anuman ang textSetting na ginamit. Kabilang dito ang isang ItemMatchCount para sa bawat pattern na tumutugma sa isang ibinigay na file.

<gw:WordItem>
    <gw:Name>Glasswall</gw:Name>
    <gw:ItemMatchCount>1</gw:ItemMatchCount>
    <gw:Locations>
        <gw:Location>
            <gw:Offset>463</gw:Offset>
            <gw:Page>0</gw:Page>
            <gw:Paragraph>0</gw:Paragraph>
        </gw:Location>
    </gw:Locations>
</gw:WordItem>

Mga function ng API​

Status​

Ang mga API na GwWordSearch at GwWordSearchDone ay nagbabalik ng isang Status na nagpapahiwatig ng resulta ng API call. Ang API na GwWordSearchTranslateStatus ay nagbabalik ng paglalarawan para sa ipinasa na Status.

C++​

Ang bawat isa sa mga API ay nagbabalik ng isang Status, na tinutukoy gaya ng sumusunod:

enum Status {
    ws_disallowedItemFound = -1024,
    ws_requiredItemNotFound = -1025,
    ws_illegalActionRedact = -1026,
    ws_illegalActionRequire = -1027,
    ws_illegalActionNoRequire = -1028,
    ws_filetypeUnsupported = -1029,
    eFail = 0,
    eSuccess = 1,
};

C#​

Upang maisama ang Glasswall Word Search sa C#, kinakailangan ang Glasswall Word Search C# wrapper. Ang bawat isa sa mga API ay nagbabalik ng isang WordSearchStatus type, na tinutukoy gaya ng sumusunod:

/// <summary>
///     Indicates whether the Word Search process was successful (WordSearchStatus.Success)
///     or not (WordSearchStatus.Fail). Zero or negative values indicate a failure.
/// </summary>
public enum WordSearchStatus
{
    DisallowedItemFound = -1024,
    RequiredItemNotFound = -1025,
    IllegalActionRedact = -1026,
    IllegalActionRequire = -1027,
    IllegalActionNoRequire = -1028,
    FiletypeUnsupported = -1029,
    Fail = 0,
    Success
}

Java​

Upang maisama ang Glasswall Word Search sa java, kinakailangan ang Glasswall Word Search Java wrapper. Bawat isa sa mga API ay nagbabalik ng uri na GlasswallWordSearchResult`, na tinutukoy gaya ng sumusunod:

package com.glasswallsolutions;

/**
 * Class used to hold the results from a Word Search process.
 */
public class GlasswallWordSearchResult
{
    /**
     * The XML analysis report
     */
    public String report;

    /**
     * The processed document
     */
    public byte[] outputDocument;

    /**
     * boolean indicating whether the process was successful (true) or not (false)
     */
    public boolean success;

    public GlasswallWordSearchResult()
    {
        report = null;
        outputDocument = null;
        success = false;
    }
}

Python​

Upang maisama ang Glasswall Word Search sa Python, kinakailangan ang Glasswall Python wrapper. Bawat isa sa mga API ay nagbabalik ng isang generic na GwReturnObj object, na maglalaman ng mga attribute na: "status" (int), "output_file" (bytes), "output_report" (bytes). Ang mga int status ay tinutukoy gaya ng sumusunod:

# glasswall\libraries\word_search\successes.py

class Success(WordSearchSuccess):
    """ WordSearch success code 1. """
    pass


success_codes = {
    1: Success,
}

# glasswall\libraries\word_search\errors.py

class UnknownErrorCode(WordSearchError):
    """ Unknown error code. """
    pass

class Fail(WordSearchError):
    """ WordSearch error code 0. """
    pass


class DisallowedItemFound(WordSearchError):
    """ WordSearch error code -1024. Item disallowed by policy found in file. """
    pass


class RequiredItemNotFound(WordSearchError):
    """ WordSearch error code -1025. Item required by policy not found in file. """
    pass


class IllegalActionRedact(WordSearchError):
    """ WordSearch error code -1026. Redact action specified but filetype doesn't support redaction. """
    pass


class IllegalActionRequire(WordSearchError):
    """ WordSearch error code -1027. Require action specified but filetype doesn't support redaction. """
    pass


class IllegalActionNoRequire(WordSearchError):
    """ WordSearch error code -1028. Require action not specified but filetype needs one. """
    pass


class FiletypeUnsupported(WordSearchError):
    """ WordSearch error code -1029. Filetype supported by Editor but not by Word Search. """
    pass


error_codes = {
    0: Fail,
    -1024: DisallowedItemFound,
    -1025: RequiredItemNotFound,
    -1026: IllegalActionRedact,
    -1027: IllegalActionRequire,
    -1028: IllegalActionNoRequire,
    -1029: FiletypeUnsupported,
}

JavaScript​

Upang maisama ang Glasswall Word Search sa JavaScript, kinakailangan ang Glasswall Word Search JavaScript wrapper. Bawat isa sa mga API ay nagbabalik ng uri na WordSearchStatus, na tinutukoy gaya ng sumusunod:

/**
 * Used to indicate whether the Word Search process was successful or not
 */
export const enum WordSearchStatus {
    ws_disallowedItemFound = -1024,     
    ws_requiredItemNotFound = -1025,    
    ws_illegalActionRedact = -1026,     
    ws_illegalActionRequire = -1027,    
    ws_illegalActionNoRequire = -1028,  
    ws_filetypeUnsupported = -1029,
    eFail    = 0,
    eSuccess = 1,
}

GwWordSearch​

Ginagamit ito upang tawagin ang Word Search engine, iproseso ang tinukoy na input file, at gumawa ng output file kasama ng isang Word Search analysis report.

C++​

Status GwWordSearch(
    void* input_buffer,
    size_t input_buffer_len,
    void** output_buffer,
    size_t* output_buffer_len,
    void** output_report_buffer,
    size_t* output_report_buffer_len,
    const char* homoglpyhs,
    const char* xml_config_string
)

C#​

Upang maisama ang Glasswall Word Search sa C#, kinakailangan ang Glasswall Word Search C# wrapper.

public WordSearchStatus GwWordSearch(
    byte[] inputBuffer,

        output_directory (str): The output directory where the redacted files will be written.
        output_report_directory (Optional[str], optional): Default None. If str, the output directory where analysis reports for each redacted file will be written.
        content_management_policy (Union[str, bytes, bytearray, io.BytesIO)]): The content management policy to apply.
        homoglyphs (Union[None, str, bytes, bytearray, io.BytesIO)], optional): Default None. The homoglyphs file path, str, or bytes.
        raise_unsupported (bool, optional): Default True. Raise exceptions when Glasswall encounters an error. Fail silently if False.

    Returns:
        redacted_files_dict (dict): A dictionary of file paths relative to input_directory, and glasswall.GwReturnObj with attributes: "status" (int), "output_file" (bytes), "output_report" (bytes)

GWWordSearchDone​

Ginagamit ito upang i-release ang anumang resources na na-allocate ng Word Search engine. Kailangang tawagin ang function na ito pagkatapos ng bawat tawag na ginawa sa GwWordSearch function, kung hindi ay magkakaroon ng memory leaks.

Ang API call na ito ay kinakailangan lamang sa C++.

C++​

Status GwWordSearchDone(
    void** output_buffer,
    size_t* output_buffer_len,
    void** output_report_buffer,
    size_t* output_report_buffer_len)

Iba pang mga wika​

Para sa lahat ng wikang saklaw ng Glasswall wrappers, ang GwWordSearchDone API function ay internal na tinatawag sa loob ng wrapper, ibig sabihin ay hindi naka-expose ang API sa user.

GwWordSearchVersion​

Ginagamit ito upang makuha ang kasalukuyang numero ng bersyon ng library.

C++​

const char* GwWordSearchVersion(void)

GwWordSearchTranslateStatus​

Isalin ang ibinigay na error code sa isang user-friendly na mensahe ng error.

C++​

const char* GwWordSearchTranslateStatus(Status errorCode)

Mga karaniwang isyu​

Hindi nagpo-process ng mga file ang Word Search​

Kapag pinapatakbo ang Word Search, pakitiyak na ang lahat ng Embedded Engine libraries ay nasa iisang directory, na kailangan ding itakda bilang current working directory. Naghahanap ang Glasswall sa loob ng current working directory para sa mga dependency nito at kung hindi makita ang mga ito, hindi mapo-process nang tama ang mga file. Tiyakin din na mayroong valid licence key.

Halimbawa ng paggamit​

Narito ang isang halimbawang application na kumukuha ng input file, pinoproseso ito gamit ang Glasswall Word Search engine, at pagkatapos ay gumagawa ng output file kasama ng isang Word Search analysis report. Inaasahan ng halimbawang application na ito ang mga sumusunod na command line parameter:

1. Path papunta sa content management configuration XML.
2. Path papunta sa homoglyphs file.
3. Path sa input file na ipo-process.
4. Path sa output file kung saan ise-save ang naprosesong file.
