If you want something a little more quick-and-dirty than SSLLabs's test (which is excellent!), you could use this tool: https://github.com/ChristopherSchultz/ssltest You will need to compile it; or I can sent you an executable JAR file if you trust me. - -chris -BEGIN PGP SIGNATURE- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl8sJY8ACgkQHPApP6U8 pFipSxAAlF0HMCYCHIbnwBF84RmlFPdqAisKsfy8y9ssNQ5pdBzadVasq2NSfVx4 OMNe+7+BWvQApKzL6VN/8joyS2JllIUDhla9Pa2LfgycvxNsy3j3nMA5PpPKipAs 8Ki1b3eNmRr+G7X4yRrccHpragvJeKmLBJz615gNxsjpOvYIwgLNwKcJH1etdpZW RtjexJictl8KAGf/S5Gzg6ctgHoobTW1+tGohr3/U59WmGdy1rNQQbBuX9OFz3E4 K5PHmJAa7T7u+LLtw/G0SKZ6Uyk/WRrCJVLD3nSa/AmL0D/fJa+l52BMsdhsCJKG UYE5HSq8ycU2q4ly49EW1SucT0fuBkztUBHNeCKbWH3qb/yan/7QS0ZPsBQd0uI1 mFAr+ErGkuo00sGhU2UrhSQHzQ+xhmX48HebXRWHfzC131cP3t7pYedrF/nNorbh kPmSODePIWlIMMhbbpIvfsTB33YY/HkZGPhsUONEUltjnB71ljt/0886fFnDfFYp XNXhTvFVzTmh4qYmXG2YkwsVTCujyBbX68niumuphvkIHhSsF6mBvwLhtDVBPBkG zvxTamu4e/nUAhAwQeFH3dyP8iCr3MHBo+MRSHiyamU6uup0j2Uley+AoKd0ih6T +3x3iyD4vCnO9fFRAvbfOCV5vrSviUJjcss4b6PU9BKwAWGwaiQ= =HHU/ -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
