Projector will soon require integrations using our Web Services to use cipher suites with a minimum 2048 bit DH Key.
Cipher suites are sets of algorithms used to secure the connection between your application and Projector before any information is sent. One of the several actions performed is the exchange of a cipher key. The key helps one application confirm the identity of the other application. The more complex the key is, the more secure the encryption. Current best practices suggest that a certain type of key called Diffie-Hellman, or DH key, be at least 2048 bits. Therefore, we’ll start requiring cipher suites that use at least a 2048-bit DH key.
Accepted Cipher Suites
How can I tell if my app has accepted cipher suites?
The “easy” answer is that depending on your application’s TLS version, you must support at least one of the following cipher suites. However, this information may not be easily available to or known by application developers. Therefore, our recommendation is to run a test against a server we have configured with the security changes already in place. Below you will find instructions for conducting this test.
