Since Camel 2.12.3.
An OpenPGP V4 key can have a primary key and sub-keys. The usage of the keys is indicated by the so called Key Flags. For example, you can have a primary key with two sub-keys; the primary key shall only be used for certifying other keys (Key Flag 0x01), the first sub-key shall only be used for signing (Key Flag 0x02), and the second sub-key shall only be used for encryption (Key Flag 0x04 or 0x08). The PGP Data Format marshaler takes into account these Key Flags of the primary key and sub-keys in order to determine the right key for signing and encryption. This is necessary because the primary key and its sub-keys have the same User IDs.
Support of Custom Key Accessors
Since Camel 2.13.0.
There is the possibility to define your custom key accessors for encryption/signing. The above PGPDataFormat class selects in a certain predefined way the keys which should be used for signing/encryption or verifying/decryption. If you have special requirements how your keys should be selected you should use the PGPKeyAccessDataFormat class instead and implement the interfaces [PGPPublicKeyAccessor|https://github.com/apache/camel/blob/master/components/camel-crypto/src/main/java/org/apache/camel/converter/crypto/PGPPublicKeyAccessor.java] and [PGPSecretKeyAccessor|https://github.com/apache/camel/blob/master/components/camel-crypto/src/main/java/org/apache/camel/converter/crypto/PGPSecretKeyAccessor.java]. There are default implementations [DefaultPGPPublicKeyAccessor|https://github.com/apache/camel/blob/master/components/camel-crypto/src/main/java/org/apache/camel/converter/crypto/DefaultPGPPublicKeyAccessor.java] and [DefaultPGPSecretKeyAccessor|https://github.com/apache/camel/blob/master/components/camel-crypto/src/main/java/org/apache/camel/converter/crypto/DefaultPGPSecretKeyAccessor.java] which cache the keys, so that not every time the keyring is parsed when the processor is called.
PGPKeyAccessDataFormat has the same options as PGPDataFormat except
{{password}}, {{keyFileName}}, {{encryptionKeyRing}},{{signaturePassword}}, {{signatureKeyFileName}}, and {{signatureKeyRing}}
