ASCIIEncoding.GetString returns different values

[jason.pileski]

I'm converting an asp.net 1.1 app to 2.0 and am having difficulty
determining why ASCIIEncoding.GetString returns a different value in
..NET 2.0 than 1.1. The code is simple but I can't locate the problem.
If someone could point out my oversight, I'd greatly appreciate it.

Thanks in advance!

Dim md5Hasher As New MD5CryptoServiceProvider
Dim encoder As New ASCIIEncoding
Dim strHashedBytes As Byte() =
md5Hasher.ComputeHash(encoder.GetBytes(SOMESTRING))

Return encoder.GetString(strHashedBytes)

I think there were some changes in how it handles byte values > 127.
But those are outside the ASCII range and if you have that in your
data (which you most likely will have in a computed hash) you
shouldn't be using ASCIIEncoding at all.

For random binary data, you should consider using Base64 encoding
instead if you need to store a string representation of it.
