Question

Using the function from: http://msdn.microsoft.com/en-us/library/system.security.cryptography.rijndaelmanaged.aspx

public static byte[] encryptStringToBytes_AES(string plainText, byte[] Key, byte[] IV)

As you can see it returns a byte array, I want to convert the byte array to a string.

How can I convert it from a byte array to string and visa versa?

Answer 1

If you don’t care how it’s stored, an easy way is to use:

Convert byte array into string: Convert.ToBase64String(YourByteArray) and
Convert string into byte array: Convert.FromBase64String(YourString).
This will give a concise, printable ASCII representation of the byte array.
