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
