TripleDESStringEncrypt Method

Cryptocx v7 User Guide


TripleDESStringEncrypt Method

This is the method that you use to encrypt strings using the 168 bit 3DES encryption algorithm (3 * 56 Bit DES keys = 168 bit 3DES)

This method uses the standard 3DES encryption algorithm. It is complimentary to the TripleDESStringDecrypt method.



Decrypts a string with encrypted with the 3DES algorithm.


x = object.TripleDESStringEncrypt

The syntax of the TripleDESStringEncrypt method has these parts:

Part Description
object A Cryptocx v7 control.
x A string that becomes the encrypted string.


You have to specify the 3  - DES keys to use, DESKey1, DESKey2 and DESKey3


The Encrypted String - base64 encoded for ease of use in storing, for example in databases fields.

Example Sample Visual Basic Code to 3DES encrypt a string.

Where Cryptocx1 is an instance of a Cryptocx Control.

'' 3DES Encrypt a String

Dim Cryptocx As New EasyByte_Software.Cryptocxv7

Cryptocx.LicenseKey = "DEMO"

Cryptocx.DESKey1 = Des3Key1.Text

Cryptocx.DESKey3 = Des3Key3.Text

Cryptocx.InputText = txt3DESPlain.Text
