Digital Signatures with Python ( + Langchain & WebLN payment demo )

Digital Signatures explained with Python code and Streamlit. We'll move on to Macaroons, L402, Lightning payments and BitcoinLangChain in a future video. I guide you through a practical demonstration of sending a file with a digital signature and verifying it at the recipient's end.

I also show a quick preview of asking a question to chatGPT on a site I have built with FastAPI, JavaScript, and use getalby (WebLN) to pay a micrpayment for the use of it.

Videos like this take a fair bit of time to prepare so please give a thumbs up if you find it useful or if you like the sample code.
