Secure Sockets Layer
TLSv1.2 Record Layer: Alert (Level: Fatal, Description: Bad Record MAC)
Content Type: Alert (21)
Version: TLS 1.2 (0x0303)
Length: 2
Alert Message
I thought that because of AES128GCM, NIST Special Publication 800-38D. I need guidance for how to verify or Debug that. I just check the return type that shows every thing is ok.

I have got the gcm code from https://github.com/BrianGladman/modes/blob/master/gcm.h
Thank you.
