MarshallSoft Advanced Encryption Standard (AES) Library for Visual Basic (AES4VB)

The MarshallSoft Advanced Encryption Standard (AES) Library is a component library of functions used to perform encryption and decryption using the "Advanced Encryption Standard" (AES) as specified by the U.S. National Institute of Standards and Technology (NIST). See fips-197.pdf

AES is considered "strong encryption" and replaces the previous US encryption standard "Data Encryption Standard" (DES). AES is commonly used by many financial entities such as banks to protect their customer's sensitive information.

Our implementation of the Advanced Encryption Standard has been verified by running the "Advanced Encryption Standard Algorithm Validation Suite" (AESAVS), which can be found at Advanced Encryption Standard Algorithm Validation Suite

The MarshallSoft Advanced Encryption Standard (AES) Library for Visual Basic provides a simple interface to encrypt/decrypt files, strings or data from Visual Basic applications using 256-bit AES (Rijndael) encryption keys. AES4VB supports hash algorithm SHA-56, CBC and ECB mode, initialization vectors, key generation from password phrases or text as well as implements PKCS7 padding and does random byte data generation. The MarshallSoft Advanced Encryption Standard DLL's will work under all 32-bit and 64-bit Windows through Windows 11). Both Win32 and Win64 DLL's are included.

Legalities

Note that it is illegal to possess strong encryption software in some countries in the world. Do not download or use this software if it is illegal to do so in your country.

In addition, this software cannot be sold to countries on the US Embargo List. See Embargoed Countries
