Subject: [PATCH 1/5] Block TripleDES in FIPS mode (#6879)
|
||||
|
||||
* Block TripleDES in FIPS mode
|
||||
|
||||
NIST SP-800-131A rev 2 lists TripleDES Encryption as disallowed in FIPS 140-3
|
||||
decryption as legacy use. Three-key TDEA is listed as deprecated
|
||||
throughout 2023 and disallowed after 2023.
|
||||
|
||||
For simplicity we block all use of TripleDES in FIPS mode.
|
||||
|
||||
Fixes: #6875
|
||||
Signed-off-by: Christian Heimes <christian@python.org>
|
||||
|
||||
* Fix flake

Subject: [PATCH] Don't include engine.h when OPENSSL_NO_ENGINE is defined
|
||||
|
||||
Fedora 41 and RHEL 10 are deprecating and phasing out OpenSSL ENGINE
|
||||
support. Downstream has moved `openssl/engine.h` into a separate RPM
|
||||
package and is recompiling packages with `-DOPENSSL_NO_ENGINE=1`. The
|
||||
compiler flag disables PyCA cryptography's ENGINE support successfully.
|
||||
We also like to build the downstream package without the `engine.h`
|
||||
header file present.
|
||||
|
||||
This commit makes the include conditional. The `ENGINE` type is
|
||||
defined in `openssl/types.h`.
|
||||
|
||||
See: https://src.fedoraproject.org/rpms/openssl/c/e67e9d9c40cd2cb9547e539c658e2b63f2736762?branch=rawhide
