It should be nul terminated string transformed by wpa_snprintf_hex()
from streams of hex chars. For your reference, the relevant code (in
src/eap_peer/eap.c) is depicted below:

? In function eap_peer_sm_tls_event() :
    ...
    size_t len = wpabuf_len(data->peer_cert.cert) * 2 + 1;
    cert_hex = os_malloc(len);
    ...
    wpa_snprintf_hex(cert_hex, len,
                     wpabuf_head(data->peer_cert.cert),
                     wpabuf_len(data->peer_cert.cert));

Thanks for babysitting my patch. :)
