+## TLS TLS Proxy
+
+Required for Android 7.0 that does not support elliptic curves.
+
+Generate a key:
+
+```bash
+openssl req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes -keyout rsa.key -out rsa.crt -subj "/CN=imap.deuxfleurs.fr" -addext "subjectAltName=DNS:smtp.deuxfleurs.fr"
+```
+
+Run the command:
+
+```bash
+./integration/proxy.sh imap.deuxfleurs.fr:993 1993
+```
+
+Test it:
+
+```bash
+openssl s_client localhost:1993
+```
