Get proper encoded string value from decoded string

Question

I want to get proper encoded string value from decoded string.

In my database one column is storing value in this way.

UA8SMvak9gq+mjrj6C6BR9atmlA=

This value is saving from distributed memory caching in database in table.

So I am not sure from where code is generating this string.

Now I want see actual value of this string so I thought it is some Decoded string, so I tried below to see encoded string but that encoded value does not looks good.

byte[] data = Convert.FromBase64String("UA8SMvak9gq+mjrj6C6BR9atmlA=");
string decodedString = Encoding.UTF8.GetString(data);

It's encoded string looks like this :

"P\u000f\u00122���\n��:��.�G֭�P"

Any idea on this Like how I can get proper encoded string.

Answer 1

All common encoding decoded results showed invalid characters. So the original data should be binary data. It might be encrypted string or it might not be string at all.

byte[] data = Convert.FromBase64String("UA8SMvak9gq+mjrj6C6BR9atmlA=");

foreach (EncodingInfo ei in Encoding.GetEncodings())
{
    Encoding e = ei.GetEncoding();
    string decodedString = e.GetString(data);
    Console.WriteLine($"{e.EncodingName}: {decodedString}");
}
