I have successfully created GnuPG public/private key pair using RSA and RSA algorithm. How can I export a public key and private key in the form of file with the
Hint 1: gpg calls private keys 'secret' because PGP dates from before people settled on the names 'private' key for the half of an asymmetric pair held by (ideally) only one party versus 'secret' key for a symmetric value usually held by two or more mutually trusting parties but nobody else.
man gpg2 | less "+/export-secret" then
n (go to second match) shows:
--export-secret-keys --export-secret-subkeys Same as --export, but exports the secret keys instead. This is normally not very useful and a security risk. The second form of the command has the special property to render the secret part of the primary key useless; this is a GNU extension to OpenPGP and other implementations can not be expected to suc- cessfully import such a key. See the option --simple-sk-check- sum if you want to import such an exported key with an older OpenPGP implementation.
Hint 2: you can output to a file by just redirecting, or using (either of)
--output file -o file Write output to file.
However, people usually use the
.asc extension for files in 'ASCII armor(ed)' format, which is base64 with dashes-BEGIN and dashes-END lines and sometimes (including here) 822/MIME-style headers. If you want not just a file named
.asc, but a file in the usual
.asc format, use (either of)
--armor -a Create ASCII armored output. The default is to create the binary OpenPGP format.
gpg2 --export-secret-keys -a -o file.asc [keyid ...]
