Examples

The following code example sets the password encryption options if the password encryption key length is less than 40.

This example is for a document-level customization.

Private Sub DocumentPasswordEncryptionKeyLength()
    If Me.PasswordEncryptionKeyLength < 40 Then 
        Dim PasswordEncryptionProvider As String = _
            "Microsoft RSA SChannel Cryptographic Provider" 
        Dim PasswordEncryptionAlgorithm As String = "RC4" 
        Dim PasswordEncryptionKeyLength As Integer = 56
        Dim PasswordEncryptionFileProperties As Object = True 

        Me.SetPasswordEncryptionOptions(PasswordEncryptionProvider, _
            PasswordEncryptionAlgorithm, PasswordEncryptionKeyLength, _
            PasswordEncryptionFileProperties)
    End If 
End Sub
private void DocumentPasswordEncryptionKeyLength()
{
    if (this.PasswordEncryptionKeyLength < 40)
    {
        string PasswordEncryptionProvider = "Microsoft RSA SChannel Cryptographic Provider";
        string PasswordEncryptionAlgorithm = "RC4";
        int PasswordEncryptionKeyLength = 56;
        object PasswordEncryptionFileProperties = true;

        this.SetPasswordEncryptionOptions(PasswordEncryptionProvider,
            PasswordEncryptionAlgorithm, PasswordEncryptionKeyLength,
            ref PasswordEncryptionFileProperties);
    }
}
