Properties

	Name	Description
	AuthenticationProvider	Corresponding IAuthenticationProvider.
	EngineIds	Engine IDs.
	MaximumKeyLength	Return maximum encryption/decryption key length. For 3DES, returned value is 32. 3DES protocol itself requires an 24 byte key. Additional 8 bytes are used for generating the encryption IV. For encryption itself, first 24 bytes of the key are used.
	MinimumKeyLength	Returns minimum encryption/decryption key length. For 3DES, returned value is 32. 3DES protocol itself requires an 24 byte key. Additional 8 bytes are used for generating the encryption IV. For encryption itself, first 24 bytes of the key are used.
	PrivacyParametersLength	Returns the length of privacyParameters USM header field. For 3DES, field length is 8.
	Salt	Gets the salt.
	UseLegacy	Flag to force using legacy encryption/decryption code on .NET 6.
