+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.
