If you need goverment level data encryption then Ivy is for you. Ivy allows you to encrypt and decrypt via Microsoft SQL Sever 2000 Stored Procedure, User Definded Function, or any .NET application.Ivy uses the Advanced Encryption Standard (AES) Algorithm (Rijndael). The Rijndael block cipher has a variable block length and key length. Ivy uses a key size of 256 bits to produce an extremely secure encryption process. Both block length and key length can be extended very easily to multiples of 32 bits. Another reason I choose Rijndael is that it can be implemented very efficiently on a wide range of processors and hardware as well as handle large chunks of text. There is no User Interface for Ivy Encryption. All functionality is from 2 DLL files which are called from either a Stored Prodecure or User Defined Funtion which can be found in the install directory of Ivy Encryption.
