Web Services changes
There are changes in support of web services in Genero 3.21.
Security note: OpenSSL 3.0 LTS support
Starting with FGLGWS 3.10.23, 3.21.01, 4.01.05 and 5.00.00, OpenSSL 3.0 LTS is required for encryption and security.
Because OpenSSL 1.1.1 goes EOL in September 2023, it is now mandatory to use OpenSSL 3.0 LTS to get the latest security fixes.
When installing an FGLGWS package, OpenSSL 3.0 libs will be provided in FGLDIR, if no OpenSSL 3.0 exists on the system.
Starting with OpenSSL 3.0, the SHA-1 digest algorithm is no longer supported by default. The OpenSSL 3.0 libs provided in FGLDIR still have SHA-1 digest activated by default. If you want to enable SHA-1 with the system OpenSSL 3.0 libs, use a command such as update-crypto-policies --set DEFAULT:SHA1 in order to use SHA-1. However, the SHA-1 digest algorithm is no longer recommended, because it is increasingly vulnerable as computers become more and more powerful. If you are using SHA-1 with GWS crypto APIs, consider moving to SHA-256 or to a stronger secure hash algorithm.
See GWS Security for more details about security and encryption with GWS.
