Subject: [PATCH] Custodia: use a stronger encryption algo when exporting keys
The Custodia key export handler is using the default's OpenSSL encryption
scheme for PKCS#12.
This represents an issue when performing a migration from CentOS Stream 8 (C8S)
to CentOS Steam 9 (C9S) where the Custodia client running in the new C9S
replica talks to the Custodia server on C8S source server. The later creates an
encrypted PKCS#12 file that contains the cert and the key using the OpenSSL's
default encryption scheme, which is no longer supported on C9S.
This commit enforces a stronger encryption algorigthm by adding following
arguments to the Custodia server handler:
-keypbe AES-256-CBC -certpbe AES-256-CBC -macalg sha384
The new arguments enforce stronger PBEv2 instead of the insecure PBEv1.
