Unzip an AES Encrypted Text File directly into a String Variable
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. Chilkat.Zip zip = new Chilkat.Zip(); bool success; // Any string unlocks the component for the 1st 30-days. success = zip.UnlockComponent("Anything for 30-day trial"); if (success != true) { MessageBox.Show(zip.LastErrorText); return; } // 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("hamlet.zip"); if (success != true) { MessageBox.Show(zip.LastErrorText); return; } Chilkat.ZipEntry entry = null; string xmlText; entry = zip.GetEntryByName("hamlet.xml"); if (!(entry == null )) { xmlText = entry.InflateToString2(); textBox1.Text += xmlText + "\r\n"; } else { MessageBox.Show("Failed to find entry in zip"); } |
