---------------------------------------
Summary: PGPDataFormat: Sub-Key not supported for signing and
correct selection of encryption/signing key via KeyFlag
Key: CAMEL-7192
URL: https://issues.apache.org/jira/browse/CAMEL-7192
Project: Camel
Issue Type: Bug
Components: camel-crypto
Affects Versions: 2.12.2
Reporter: Franz Forsthofer
Fix For: 2.12.3, 2.13.0

0001-use-key-flags-for-determining-encryption-signing-key.patch
A PGP key ring with version 4 keys typically consists of a primary key which
has sub-keys. There is a use-case where the primary key has only the usage flag
(KeyFlag) "certify" and one sub-key is makred with the usage flag "signing" and
the other sub-key is marked with usage flag"encryption". In this case the
PGPDataFormat does not use the correct sub-key for signing and encryption.
In the patch I enabled the usage of sub-keys for the signing process and I
introduced the usage flag (KeyFlag) for finding the correct keys for signing
and encryption.
