If the option "--check" is used the passphrase constraints checks as
implemented by gpg-agent are applied. A check is not done if the
passphrase has been found in the cache.
If the option "--no-ask" is used and the passphrase is not in the
cache the user will not be asked to enter a passphrase but the error
code GPG_ERR_NO_DATA is returned.
