Transport Layer Security (TLS), formerly known as Secure Socket Layer
(SSL), is the technology that keeps the Internet secure. The most
recent version is TLS version 1.3 and is recommended for all new
software.
If you are developing client software for an earlier version of TLS,
either TLS 1.0, TLS 1.1, or TLS 1.2, and are using either the RSA or
DHE_RSA key exchange mechanisms, you can verify that it works by
connecting to my test server:
https://www.mikestoolbox.net
TLS versions 1.0, 1.1, and 1.2.
1024-bit Diffie-Hellman parameters.
Asks for a client certificate.
https://www.mikestoolbox.org
TLS versions 1.0, 1.1, and 1.2.
2048-bit Diffie-Hellman parameters.
TLS Versions and Extensions supported by both servers:
TLS Version 1.0 | RFC 2246 | |
TLS Version 1.1 | RFC 4346 | |
TLS Version 1.2 | RFC 5246 | |
Server Name Indication | RFC 4366 | |
Maximum Fragment Length | RFC 4366 | |
Truncated HMAC | RFC 4366 | |
Session Tickets | RFC 5077 | |
Signature Algorithms | RFC 5246 | |
Renegotiation Info | RFC 5746 | |
Encrypt-then-MAC | RFC 7366 | |
TLS Fallback Prevention SCSV | RFC 7507 | |
ClientHello Padding | RFC 7685 | |
GREASE | RFC 8701 |
Note: you will get security warnings if you connect with a normal browser since the server uses its own root certificate.
