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.
