Great interest here.

I actually would be interested in how he would argue if he was the
government and would want to prosecute hackers for that. Or both. Just
like the old saying: 2 lawyers, 3 opinions.

Terminal asks for passphrase even when passphrase is cached by gpg-agent

[Sudhir Khanger]

Hello,

I have gpg-agent cache passphrase. When I run gpg -c text.txt it asks for 
passphrase twice like it normally would but Kgpg or KMail don't. What am I 
suppose to do to make both terminal and GUI apps use cached passphrase instead 
of asking for one?

-c is symmetric encryption, encryption with a passphrase. It is
prompting you what the passphrase should be.

If it were to ask you for your passphrase for *decryption*, it would ask
only once (unless you make a typo).

Encryption to a public key would be:

$ gpg -r KEYID -e test.txt

and it will never ask for a passphrase, since you don't need a
passphrase for _encryption_, but rather for _decryption_.

However, also signing the file will need your passphrase, regardless of
the recipient.

By the way, it is possible to specify a "default recipient" in the
configuration file if you do not use a "-r" when encrypting a file with
"-e".

HTH,

Peter.

You probably mean that Kgpg asks just once. KMail isn't capable of 
creating symmetrically encrypted mails thus I don't know what you mean 
there.

I have created a wishlist entry to change that:

That is not possible AFAIK because a passphrase used in symmetric 
encryption is not a passphrase in the usual gpg-agent sense. gpg-agent 
is used for asking those just because it's already there.

You can call gpg in batch mode (which probably is what Kgpg does):

gpg --batch --passphrase foo --symmetric file.txt

Note that this way everyone on the system can see the passphrase in the 
argument list. You may use something like

echo -n foo | gpg --batch --passphrase-fd 0 --symmetric file.txt

instead (where echo is a shell builtin or something else that does not 
show its arguments in the process list).
