Check for weak encryption functions

If the result is positive, there is no need for further action. If the result is negative, please read the following instructions.

Result positive No weak export encryption supported
Result negativ Weak export encryption supported
Description Your server is configured to use intentionally insecure encryption methods. This allows you to decrypt communication with your server using Man-in-the-middle attacks.
Background The term Cipher Suite stands for a collection of cryptographic methods used (encryption of information). This collection includes the key exchange method, digital signature, encryption and cryptographic hash functions. This combination of cryptographic components ensures a secure connection between two parties, e.g. your mail program and a server. In the TLS protocol, the Cipher Suite (cryptographic procedure) determines which algorithms are to be used to establish a secure data connection and is decisively responsible for the security of the connection.
Consequence Attackers can easily decrypt the communication between your server and the mail program with a weak encryption methodology. This can be used to read out mail content and misuse them for criminal purposes.
Solution/Tips If Weak Export Encryption Supported is reported, disable support for EXPORT encryption methods in the web server.
