I try using MQTTBrokerExtended library exemple.

But i always get this error:

13/04/2022 10:43:11.680 ERROR Error processing protocol message: CONNECT

This can happen in Debug mode. Try running same code in Release mode.

Thanks, it work better when i modify some line in the programme.(direct return true)
But i'am not shure of encoded format in the password file.
I have test with base64, md5 and sha256, all this format seems to be wrong?
Witch encoded format is it ?

Looking at this code in the example

Dim MD5() As Byte = MD.GetMessageDigest(Password, "MD5")
Dim StoredMD5 As String = PasswordMap.Get(Username)
Return (B64.EncodeBtoS(MD5, 0, MD5.Length) = StoredMD5)

I can say that the password file format is Map containing values of MD5 hashes (as byte arrays) encoded to base64 strings.

Use this code to generate your values for passwords file:

Dim pstring As String = "1234"    'Change this to your password string
Dim pbytes() As Byte = pstring.GetBytes("UTF8")
Dim pMD5() As Byte = MD.GetMessageDigest(pbytes, "MD5")
Dim pFileValue As String = B64.EncodeBtoS(pMD5, 0, pMD5.Length)
Log(pFileValue)
