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?
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.
This can help you a lot, is about to converting into Hex format but can be very usefull How do you convert Byte Array to Hexadecimal String, and vice versa?
While using Rijndael Encryption i faced this problem, it returns encrypted byte[] (array), Convert byte[] to string;
myStringVariable= Convert.ToBase64String(myEncryptedByteArray);
Convert string to byte[];
byte[] bytes = Convert.FromBase64String(myStringVariable);
