Thanks in > advance. RSA key exchange is defined in RFC2246: https://datatracker.ietf.org/doc/html/rfc2246#section-7.4.7.1 https://datatracker.ietf.org/doc/html/rfc2246#section-8.1.1 > RSA-PKCS#1 v1.5 This is of course independent of the OpenSSL version, and indeed of OpenSSL, since it is a matter of TLS protocol interoperability and needs to be compatible across all TLS 1.0–1.2 implementations. -- Viktor.
