Do you have a faster httptp end to end encryption other than https / tls?

end to end encryption using letsencrypt etc is not very practical.
what do u recommend for a faster end to end encryption without going through a third party service?

i can write code and willing to contribute to this area.

basically just something "good enough" for two way encryption will do to prevent man in the middle attack/snooping
