Sometimes simple encryption tools are already in use for a long time and
there might be a desire to integrate them into the GnuPG framework. The
protocols and encryption methods might be non-standard or not even
properly documented, so that a full-fledged encryption tool with an
interface like gpg is not doable.
symcryptrun provides a
solution: It operates by calling the external encryption/decryption
module and provides a passphrase for a key using the standard
pinentry based mechanism through
symcryptrun is only available if GnuPG has been
configured with ‘--enable-symcryptrun’ at build time.
