Unzip Encrypted Text into a String Variable

See more Zip Examples

Demonstrates how to open an encrypted .zip archive and unzip a text file directly into a string variable. C++

#include <CkZip.h>
#include <CkZipEntry.h>

void ChilkatSample(void)
    {
    bool success = false;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkZip zip;

    // Set the password required for decrypting.
    zip.put_DecryptPassword("myPassword");

    success = zip.OpenZip("encrypted.zip");
    if (success == false) {
        std::cout << zip.lastErrorText() << "\r\n";
        return;
    }

    // Locate the file within the Zip to be unzipped into a string variable:
    CkZipEntry entry;
    success = zip.EntryMatching("*.csv",entry);
    if (success == false) {
        std::cout << zip.lastErrorText() << "\r\n";
        return;
    }

    // lineEndingBehavior:
    // 0 = leave unchanged.
    // 1 = convert all to bare LF's
    // 2 = convert all to CRLF's
    int lineEndingBehavior = 0;
    const char *srcCharset = "utf-8";

    const char *strCsv = entry.unzipToString(lineEndingBehavior,srcCharset);
    std::cout << strCsv << "\r\n";
    }
