Syntax

Encrypt3DES( in sData : string,
             in sKey1 : string optional, 
             in sKey2 : string optional,
             in sKey3 : string optional ): string;

Return value

encrypted string

Parameter	Description
sData	String or binary data to be encrypted
sKey1	String or binary data used as first encryption key (optional).
sKey2	String or binary data used as second encryption key (optional).
sKey3	String or binary data used as third encryption key (optional).

注: The returned string is about 30% larger in size than the original data.

Example

dcltrans
  transaction TMain
  var
    sUserPass  : string;
    sEncrypted : string;
  begin
    // Build your own authentication header
    AttributeGetString("Password", sUserPass);
    sEncrypted := Encrypt3DES(sUserPass);
    Print(sEncrypted);
    sUserPass := Decrypt3DES(sEncrypted);
    Print("decrypted password: " + sUserPass);
  end TMain;
