[Gpg4win-users-en] Can Anyone Tell Me How to Distinguish Between Keys in a Key Pair After Generation?

[Juan Miguel Navarro Martínez]

If they are in the keyring: gpg -k|--list-keys for public keys and gpg
-K|--list-secret-keys for secret keys.

If you exported the keys not armored, you can either use gpg <key
file> and it should say either sec and ssb (for secret master key and
subkeys respectively) or pub and sub (for public master key and
subkeys respectively. Like this:

C:\Users\Juanmi>gpg2 public.key
pub  4096R/0x88E2947F9BC6B3CF 2014-11-17 [expires: 2016-11-16]
      Key fingerprint = 5A91 90D4 CF27 9D52 D62A  BC58 88E2 947F 9BC6 B3CF
[...]
sub  2048R/0x42DF3EE44F24807B 2014-11-18 [expires: 2015-11-18]

C:\Users\Juanmi>gpg2 secret.key
sec  4096R/0x88E2947F9BC6B3CF 2014-11-17
      Key fingerprint = 5A91 90D4 CF27 9D52 D62A  BC58 88E2 947F 9BC6 B3CF
[...]
ssb  4096R/0xF48F3C472370A536 2014-11-17
ssb  2048R/0x42DF3EE44F24807B 2014-11-18

Another option is to use:

    (For Mac/Linux) gpg --list-packets [keyfile] | grep secret
    (For Windows) gpg --list-packets [keyfile] | findstr secret

or:
    (For Mac/Linux) gpg --list-packets [keyfile] | grep public
    (For Windows) gpg --list-packets [keyfile] | findstr public

To see if that key file is a public key or a secret key.

PS: You are somehow replying in threads instead of creating new threads.
