How to add a new options to gpg command line

Question

When I use gpg to encrypt files, I can use -c, or --symmetric, and also -a for armor.

-c, --symmetric     encryption only with symmetric cipher
-a, --armor           create ascii armored output

How can I add -g, so that the command would be gpg -c -g AES25, instead of gpg -c --cipher-algo AES25?

Answer 1

You can't do it directly with gpg. The code which is compiled to make gpg supports certain command line options, and some of those have aliases, but it's not something you change directly.

You could write a script/wrapper for gpg (say, call it my-gpg) which took one set of command line options and then converted them into the options gpg expects.

So you could write the script, and then use,

my-gpg -c -g AES25

and the script would in turn run

gpg -c -cipher-algo AES25

But you'd need to implement that yourself. You could use a simple bash alias to achieve the same thing as well.
