--armor-a--base64--assume-armor--assume-base64--assume-binary--p12-charset nameLatin1 and CP850. Note
that gpgsm itself automagically imports any file with a
passphrase encoded to the most commonly used encodings.
--default-key user_id--local-user user_id-u user_id--recipient name-r--output file-o file--with-key-data--list-keys commands. Especially
a line tagged grp is printed which tells you the keygrip of a

import is done and only imported if it succeeds the test. Note that
this does not affect an already available cwertificate in the DB.
This option is therefore useful to simply verify a certificate.
