CkPython Requires Chilkat v11.0.0+

Unzip an AES Encrypted Text File directly into a String Variable

See more Zip Examples

A common need is to unzip from an AES encrypted Zip archive directly into a string variable, such that the unencrypted file never resides on disk, even temporarily. This example shows how to do it. CkPython

import sys
import chilkat

success = False

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

zip = chilkat.CkZip()

#  This example opens a WinZip-compatible AES encrypted
#  .zip that contains a single file: hamlet.xml.

#  It decrypts and unzips hamlet.xml directly into a string
#  variable.
zip.SetPassword("secret")
success = zip.OpenZip("qa_data/hamlet.zip")
if (success == False):
    print(zip.lastErrorText())
    sys.exit()

entry = chilkat.CkZipEntry()
success = zip.EntryOf("hamlet.xml",entry)
if (success == False):
    print(zip.lastErrorText())
    sys.exit()

#  lineEndingBehavior:
#  0 = leave unchanged.
#  1 = convert all to bare LF's
#  2 = convert all to CRLF's
lineEndingBehavior = 0
srcCharset = "utf-8"
xmlText = entry.unzipToString(lineEndingBehavior,srcCharset)
print(xmlText)
