2015年12月18日 · The signature is correct, but GnuPG could not verify the key's validity, thus the signature is not deemed valid. With other words, GnuPG explains you that while the signature is issued by a totally valid key, the key could have issued by anybody (you can create keys for arbitrary mail addresses, there is no central instance verifying them ...
gnupg - What is the most robust available algo for GPG symmetric ...
GnuPG version 2.1 uses AES (128 bit key) as the default, so if you have that version you don't need to tweak the default at all. Older versions default to CAST5, but if they support AES it is worthwhile to override that default. (Neglecting to do so shouldn't be a cause for alarm, however.)
