Cryptocx v7 User Guide

BlowfishFileEncrypt Method

This is the method that you use to encrypt a file using 448 bit strength blowfish encryption. This method is complementary to the BlowfishFileDecrypt method that decrypts the file.

Description

Encrypts a file using 448 bit Blowfish Encryption.

Syntax

x = object.BlowfishFileEncrypt

The syntax of the BlowfishFileEncrypt method has these parts:

Part Description

object A Cryptocx v7 control.

x A string that becomes either "TRUE" or "Error: xxx" where xxx is the error message.

Remarks

If for whatever reason the method fails to complete, the method will return some text stating exactly what has gone wrong, if the method runs ok then the output from the method will = "TRUE".

If you specify a Password that is not 56 characters in length when encrypting (448 bit encryption) Cryptocx will use SHA hashing to create a 56 character password, using your initial password as the seed for SHA.

Returns

"TRUE" or a string stating what went wrong beginning with "Error:"

Example

Sample Visual Basic Code to encrypt a file using blowfish:

Where Cryptocx1 is an instance of a Cryptocx Control.

Cryptocx1.Password = txtBlowFilePass.Text
Cryptocx1.SourceFile = txtSourceFileBlow.Text
Cryptocx1.DestinationFile = txtDestinationFileBlow.Text
theResult = Cryptocx1.BlowfishFileEncrypt

'' Check to see what has happened (if the encryption went ok without errors)
''
If theResult = "TRUE" Then
'' Ok, the Encryption went well with no errors
Else
MsgBox theResult
End If
