Workbook.SetPasswordEncryptionOptions Method (Object, Object, Object, Object)

 

Sets the options for encrypting the workbook using a password.

Namespace:   Microsoft.Office.Tools.Excel
Assembly:  Microsoft.Office.Tools.Excel (in Microsoft.Office.Tools.Excel.dll)

void SetPasswordEncryptionOptions(
	object PasswordEncryptionProvider,
	object PasswordEncryptionAlgorithm,
	object PasswordEncryptionKeyLength,
	object PasswordEncryptionFileProperties
)

Parameters

PasswordEncryptionProvider
Type: System.Object

A case sensitive string of the encryption provider.

PasswordEncryptionAlgorithm
Type: System.Object

A case sensitive string of the algorithmic short name (i.e. "RC4").

PasswordEncryptionKeyLength
Type: System.Object

The encryption key length, which is a multiple of 8 (40 or greater).

PasswordEncryptionFileProperties
Type: System.Object

true (default) to encrypt file properties.

The PasswordEncryptionProvider, PasswordEncryptionAlgorithm, and PasswordEncryptionKeyLength parameters are not independent of each other. A selected encryption provider limits the set of algorithms and key length that can be chosen.

For the PasswordEncryptionKeyLength parameter there is no inherent limit on the range of the key length. The range is determined by the Cryptographic Service Provider which also determines the cryptographic algorithm.

For information on optional parameters, see Optional Parameters in Office Solutions.
