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)
