RC4 Encryption Module


Encryption rate is 5 million bytes per second on a 400 MHz PII laptop - You will not find faster (VB) RC4 code here or elsewhere.
The code is extreamly fast, modular, and easily readable and modifiable.
A simple sample project that uses the module to encrypt files is included in the ZIP.

Original Author: unknown

Inputs

An array of bytes to be encrypted or decrypted, and a variable length passphrase string

Assumptions

The RC4 cipher is excellent for encrypting files. It is not well suited for string encryption if the ciphertext is to appear in a text box.

Returns

Ciphertext or Plaintext 100% compatible with the RC4 cipher

API Declarations

none
(GetOpenFileName and GetSaveFileName from Library "comdlg32.dll" is used in a demonstration of the module)
