    How to change keyid format from 40 to 16 digits lenght when GnuPG
    verify a signature?

    The keyid may be specified using 40 hex characters or using 8 hex characters. gpg --list-key 0xA97B385144E498D9157EDA1039B84EA598B013E0
    and
    gpg --list-key 0x98B013E0

    The leading 0x can be ommitted. It's used for consistency with old versions
    of pgp.

    Note the 8 hex char version is identical to the last 8 hex characters of the long version.

    If you're asking how to get gpg to only show the short version, I don't think it can be done. The long version exists and is used as there have been key id collisions using only the 8 hex character version.

    While the short version is still allowed, there is a risk that it may match more than one key. Continue using it at your own risk.

    The long "key ID" (40 hex digits) is actually the key's fingerprint.

    Actual key IDs are 8 hex digits. For DH/DSS keys and modern RSA keys ,
    the last 8 hex digits of its fingerprint are the key ID. For legacy RSA
    keys, the key ID is distinct from the key ID.

    gpg: Signature made Sun Jun 19 14:24:02 2022
    gpg: using EDDSA key ooooooooooooooooooooooooxxxxxxxxxxxxxxxx

    In this example GnuPG concatenate unknown digits to my Key ID.

    "xxxxxxxxxxxxxxxx" correspondent to my key ID. What is "oooooooooooooooooooooooo" I have no idea. Could anyone tell me
    what is it?
