Question

I want to make a Software which decodes Base64-encoded text strings and vice versa.
Any help provided on the topic with coding in Visual Basic will help me a lot.
Thank you.
Note:-c# language can also be implemented

Answer 1

You need to call Convert.ToBase64String and Convert.FromBase64String.

These methods convert byte arrays to and from Base64.

If you want to encode a string in Base64, you’ll need to convert it to a byte array by calling Encoding.Unicode.GetBytes(str) and Encoding.Unicode.GetString(bytes). (In the System.Text namespace)

Note that Base64 should never be used for encryption, except to convert a byte array that was already encrypted into a string.

If you want to encrypt data, use the RijndaelManaged class.
