icspasymmetricalgorithm.cls

这是一个在vb下实现的各种加密程序,可以实现一般的文本加密和文件加密,但是很多算法都是已经被人破解过的.

' Provices methods to allow access to Key container information and Crypto API blob import/export ability
' for Asymmetric algorithmes.
'
' @remarks This interface provides a common set of methods used to retrieve information about an Asymmetric
' algorithm's key container and provides the ability to import and export Byte arrays represetning Crypto
' API blobs used by Microsoft Cryptography Service Providers.

' @see RSACryptoServiceProvider
