MarshallSoft AES Library for Visual Basic

MarshallSoft AES Library for Visual Basic (AES4VB) is a lightweight component library dedicated to developers who want to integrate encryption and decryption features into their Visual Basic programs. It uses the 256-bit AES (Advanced Encryption Standard) algorithm to encrypt and decrypt files, data and strings of characters. Also known as Rijndael, this encryption method is widely used by financial and governmental institutions for securing sensitive information, such as banking details.

Besides implementing the 256-bit AES algorithm, AES4VB supports ECB (Electronic Cookbook), CBC (Cipher Block Chaining), SHA-256 (Secure Hash Algorithm 256) and PKCS7 (Cryptographic Message Syntax Standard) padding, the last one being used for signing and/or encrypting messages under a PKI (Public Key Infrastructure). AES4VB can produce random byte data and keys from password phrases and plain text.

This component library works with all versions of Microsoft Visual Studio until Visual Studio 2005 as well as Visual Basic version 4, 5 and 6. It doesn't depend on any support libraries because it only calls Windows API functions. Moreover, MarshallSoft AES Library for Visual Basic can be installed on all 32- and 64-bit Windows versions until Windows 10. The DLL file has two prices available, including and excluding the C source code.
