I came across this thread after having the same MD5 issues that initially started the thread. Since I'm working in Windows / C#, I figured I would provide my C# 3.0 Extension Method that *appears* to create a valid MD5 hash (ie, I haven't had any problems with it yet)
public static string CreateMD5Hash(this byte[] contentsToHash)
{
System.Security.Cryptography.MD5 hasher = System.Security.Cryptography.MD5.Create();
byte[] hashBytes = hasher.ComputeHash(contentsToHash);
StringWriter writer = new StringWriter();
foreach (byte b in hashBytes)
{
writer.Write("{0:x2}", b);
}
return writer.ToString();
}
Does this look right to you smugmug experts out there? If so, what about adding a little note in the documentation that clearly shows some examples in C#, Java, PHP, Perl, etc on how to create MD5 hashes that sugmug understands. I don't think that the the user should need to to surf the dgrin forums to figure out how to MD5 hash their image.
