1. Decode the RFC 6455 sample frames
Backend developerBackground
A captured hex dump contains the specification’s own masked “Hello” text frame, an unmasked ping and a close frame with status 1000 and reason “bye”.
Problem
Need to confirm opcodes, masking key, unmasked payload and close-code parsing without writing a custom decoder.
How to use
Paste the hex dump into the frames field and leave input encoding on Auto-detect.
