Using 64 bit OpenSSL Kit on Windows.

Dear SSL,

Your encryption kit is supreme.  I have been using it to build self-signed web certificates
and email certificates.  I have also been using it to encrypt and decrypt messages,
all via RSA.  I am running OpenSSL using 64 bit Windows 10, which is different
to Linux, a little bit.

-I can do error checks on rsa private keys.

openssl rsa -check -in private.key -noout

  1.  How can I do something parallel to this, to do an error check on a public key, so
that it also replies with a command line message saying whether a public
key is alright, or not?

  1.  If I have an rsa private/public key pair, in two different files, what openssl
command can I run to verify if these two keys match one another, accurately?

  1.  If I have a private key and a .crt web certificate, what openssl command
can I run to verify if these two files continue to match?

  1.  If I have a Thunderbird Email certificate, in pkcs12 format, can I run openssl
to verify that with the .crt certificate that came before it?
  3.  And how can I verify between the pkcs12 email certificate and the original private key?

Yours Sincerely,
