*You* are not vulnerable. The *server* may be vulnerable. Sessions between your client and a vulnerable server are vulnerable. DROWN is an attack on servers that use RSA keys and support SSLv2. The client cannot prevent this attack - it has to be mitigated at the server end. -- Michael Wojcik Technology Specialist, Micro Focus -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
