Our documentation regarding FIPS 140 claimed that when using SAML
in a JVM that is configured in FIPS approved only mode, one could
not use encrypted assertions. This stemmed from a wrong
understanding regarding the compliance of RSA-OAEP which is used
as the key wrapping algorithm for encrypting the key with which the
SAML Assertion is encrypted.
However, as stated for instance in
https://downloads.bouncycastle.org/fips-java/BC-FJA-SecurityPolicy-1.0.0.pdf
RSA-OAEP is approved for key transport, so this limitation is not
effective.
This change removes the limitation from our FIPS 140 related
documentation.
This change makes the process of verifying the signature of
official plugins FIPS 140 compliant by defaulting to use the
BouncyCastle FIPS provider and adding a dependency to bcpg-fips
that implement parts of openPGP in a FIPS compliant manner.
In already FIPS 140 enabled environments that use the
BouncyCastle FIPS provider, the bcfips dependency is redundant
but doesn't cause an issue as it will be added only in the classpath
of the cli-tools
This is a backport of #44224
This commit removes the fallback for SSL settings. While this may be
seen as a non user friendly change, the intention behind this change
is to simplify the reasoning needed to understand what is actually
being used for a given SSL configuration. Each configuration now needs
to be explicitly specified as there is no global configuration or
fallback to some other configuration.
