HTTPS/SSL Manage Certificates - lots of duplicate (null?) entries

  • When I try to manage certificates I see (under Keychain Access) the following oddities:

    1. Under login I see 3 lines of the form etc, 2 of which are identified as revoked. Can I and should I delete the 2 revoked entries?

    2. Under the category heading I see 1047 items listed, predominantly duplicates with no sub-entries:

    2 entries "<key> public key no dates
    <key> private key no dates

    7 entries "Apple ID {a constant email address} key public key no dates
    4 entries "Apple ID {a constant email address} key private key no dates
    of the 4 above, the last 3 have a sub entry as follows{constant very long certificate number} certificate expiry dates,various 2017

    The remaining (over 1000) entries are nearly identical, without sub-items and of the general form:
    iMessage encryption key public key
    private key
    iMessage signing key public key
    private key

    I'm running El Capitan because Sierra was unusably unstable, and I wonder if there is anything for me to be concerned about in the information above.
