Nginx - how to enable the old encryption algorithm?

Question

Nginx

There is an old push-button phone that does not support tls, only simple ciphers, like this one https://sha256.badssl.com
How to make nginx return sha256, without tls? To be able to access the site via https through the browser of this phone?

Answer 1

ssl_protocols SSLv2 SSLv3;
ssl_ciphers ALL:!aNULL:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;

Root certificates are clearly outdated on the old push-button phone, so it will work, but it will still swear at certificates.

Answer 2

You need to change the browser of this phone to one that supports this version of encryption.
And at the same time, take into account that stronger encryption requires more performance from hardware and older devices may not be able to cope with this in a reasonable time.

Answer 3

Maybe this will help?
