Is it possible to decrypt data in SQL if it was encrypted in .net?

Last Modified: 2012-05-05
Is it possible, using either SQL2000 or SQL2005, to decrypt data that was encrypted by the front-end .net web code? (On the website, data was encrypted before being imported into database table).

I'm not familiar with web, but I do know that PasswordDerviceBytes and Rijndael was used to encrypt:
PasswordDeriveBytes Object = PasswordDeriveBytes(ThePassword, new byte[] {0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d,  0x65, 0x64, 0x76, ....});
Rijndael alg = Rijndael.Create();
alg.Key = Key;
alg.IV = IV;

I have access to the data and know ThePassword. Using the password, is there a SQL script that can decrypt the data? (The ultimate goal is to deliver this data in a file, with the data in un-encrypted format so the users can read it)

I'm not sure if this is possible? A similar question was asked here but never answered: https://www.experts-exchange.com/Community_Support/General/Q_22028650.html?sfQueryTermInfo=1+data+decrypt+passwordderivebyt
