Converting the Rijndaelmanged() byte[] to a string

Question

Hi,

I want to convert the Rijndaemanaged() encrpted value to a string.

Will ToBase64String() suffice? It says its only for 8-bit arrays, but AES is 128 bit right?

Update

For the encrption, I am using the code from http://msdn.microsoft.com/en-us/library/system.security.cryptography.rijndaelmanaged.aspx

Answer 1

Byte is byte = 8bits. ToBase64String will work. As Jon points out, it has limitations in using it in urls or filenames.

You can use this to convert it to a hex string.

Answer 2

Base64 is a generally good way to go. It's reasonably efficient, and you usually don't need to worry about encoding issues as the result will be ASCII. However, you should probably be careful if you're going to use the result in a URL - "normal" Base64 isn't url-safe. (There are alternative encodings which use different symbols though.)

Answer 3

We have been succesfully using Convert.ToBase64String on the encrypted bytes from managed Rijndael for number of years.
