-Encourage our old python3-cryptography to at least start to work with OpenSSL 3.
-
-- Backport one patch to err.py to remove a symbol which has been removed in
-  OpenSSL 3, and isn't used in python3-cryptography.
-  (50ec692749b7e2e62685b443f5e629627b03987e)
-
-- Backport the detection of OpenSSL 3 and don't link to FIPS_mode/FIPS_mode_set
-  (parts of f08a7de651f9e6475c8c0a67d2a61ed8b669ddf6)
-
-This is *not* a complete backport of the 3.0 support, but is enough that packages
-such as imgtool can import python3-cryptography and operate until the upgrade is
-ready.
