Hello I setup a Freeradius server to do EAP-TLS with Android devices (freeradius 3.2.x) I use the default config for EAP-TLS with the default Makefile for certs and keys I use OpenSSL version 3.0.2 (and I have tried with openssl 1.1.1t) I have tested with two Android version, 10 and 13. I get an error using client key and cert on Android (and only on it) With the same key and cert it works on an embedded Linux and on Windows. With OpenSSL version 3.0.2, I must use the "-legacy" option on openssl pkcs12 command line to be able to import natively a p12 file. (not in openssl 1.1.1t) Indeed in openssl 3.0.x version they removed old algorithm as stated here : https://stackoverflow.com/questions/71872900/installing-pcks12-certificate-i... Then, even by using "-legacy" on OpenSSL 3.0.2 or using OpenSSL 1.1.1 for creating p12 container I can't use the imported keys in my Android phone. When I try to connect to my freeradius network I get on adb logcat (phone side) : wpa_supplicant: TLS - SSL error: error:0900006e:PEM routines:OPENSSL_internal:NO_START_LINE So, as using default keys and cert with the two openssl LTS version does not work with my freeradius 3.2.0 setup, what is your configuration for your Android devices ?
