Using Passwords to Protect Zip Files

To create password-protected zip files, set the Password property to a non-empty string before creating any entries. Each entry may have its own password. For example:

• Visual Basic

C1Zip.Password = "password"

C1Zip.Entries.Add(someFile)

• C#

C1Zip.Password = "password";

C1Zip.Entries.Add(someFile);

To extract this entry later, the Password property must be set to the same value in effect when the entry was added. For example:

• Visual Basic

' Will fail, password not set.

C1Zip.Password = ""

C1Zip.Entries.Extract(someFile)

' Will fail, wrong password.

C1Zip.Password = "pass"

C1Zip.Entries.Extract(someFile)

' Will succeed.

C1Zip.Password = "password"

C1Zip.Entries.Extract(someFile)

• C#

// Will fail, password not set.

C1Zip.Password = "";

C1Zip.Entries.Extract(someFile);

// Will fail, wrong password.

C1Zip.Password = "pass";

C1Zip.Entries.Extract(someFile);

// Will succeed.

C1Zip.Password = "password";

C1Zip.Entries.Extract(someFile);
