Yesterday, I wrote how to encrypt a password using a one-way MD5 hash, but as some of the comments point out, the MD5 algorithm is not strong enough. I listened and wrote a new encryption method that uses SHA256 instead of MD5.
public string Encrypt(string plainMessage)
byte data = Encoding.UTF8.GetBytes(plainMessage);
using (HashAlgorithm sha = new SHA256Managed())
byte encryptedBytes = sha.TransformFinalBlock(data, 0, data.Length);
If I pass my own name to the Encrypt method this would be the result:
