Hello

Is there a way to determine the key length and the type of key (RSA or
other) used when generating  the keyring?  I have a RHEL 5 box using gpg
1.4.5 where I need to determine how a key ring was generated.    Even on an
Ubuntu box using gpg2, the –list-secret-keys option does not print out that
information.

Thank you.

gpg -K or gpg --list-keys or gpg --list-secret-keys should all print the
information you are interested in.


In my example the primary key is rsa3072 and encryption subkey is rsa4096.
You can see this info before creation date if the key.

Note that gnupg older 1.x does not support ecc, only rsa/rsa and rsa/dsa.

~# gpg --list-secret-keys

sec   rsa3072 2017-11-15 [SC]
      8275276834C8F08567185C92FB3157AB136ED940
uid           [ultimate] Test Test
ssb   rsa4096 2017-11-15 [E]

This is gnupg 2.2. How does it look at your side?
