Do not use MD5!! It has been broken for years and was officially reported as unsafe to use in 2008 (at least that's earliest I can find). Please use SHA2 or one of those families algorithms. To do this look into the System.Cryptography namespace.

Thanks,
Ed

MD5 is a cryptographic hash function, not an encryption function. The difference is hash functions are one-way only. You cannot decrypt the hash back into the original content. Well, at least you're not supposed to. MD5 has been considered broken for years now.
