How We'll Encrypt the Web [video]
It's critical that we create a more secure and privacy-respecting Web by moving
all websites to HTTPS. I'll talk about a practical technical plan for getting
there as quickly as possible, including the role that Let's Encrypt has to
play, how Let's Encrypt works, and challenges we've faced. I hope to leave
people feeling optimistic about moving the Web to HTTPS, and with a better
sense of what they can do to help.
Speaker Bio
Josh Aas is a co-founder and the Executive Director of Internet Security
Research Group (ISRG), the non-profit organization behind the Let's Encrypt
certificate authority. Before ISRG and Let's Encrypt, Josh spent more than a
decade as an engineer and strategist with Mozilla.
