c# - What's the best way to encrypt short strings in .NET?

Question

My boss wants me to encrypt some information used during data transfer. The individual strings to be encrypted are between eight and twenty characters long. A single password must be used to encrypt and decrypt so I need a symmetric alogrithm. I don't want to roll my own - I want to use one built into .NET from C#.

So, which algorithm is best?

Answer 1

TripleDes ?

You can use the System.Security.Cryptography.TripleDESCryptoServiceProvider

Small amount of code to encrypy/decrypt... does exactly what it says on the tin :)
