Before updating OpenSSL, you must check which version is used in your current 4D version. Below is a table that lists the OpenSSL versions for the most recent 4D versions:



Keep in mind that while it is possible to use a newer OpenSSL version of the same branch (e.g. 1.1.1 b -> 1.1.1 d), it is not possible to deviate from the same branch (e.g. 1.0.2 x -> 1.1.1 x).
