EXAMPLES

       For  more  information  about  what's  happening  --verbose  can  be  added to any command. For much more
       information --verbose=2 may be used.

       Display what version of the applet is running on the YubiKey Neo:

          yubico-piv-tool -a version

       Generate a new ECC-P256 key on device in slot 9a, will print the public key on stdout:

          yubico-piv-tool -s 9a -A ECCP256 -a generate

       Generate a certificate request with public key from stdin, will print the resulting request on stdout:

          yubico-piv-tool -s 9a -S '/CN=foo/OU=test/O=example.com/' -P 123456 \
            -a verify -a request

       Generate a self-signed certificate with public key from stdin, will  print  the  certificate,  for  later
       import, on stdout:

          yubico-piv-tool -s 9a -S '/CN=bar/OU=test/O=example.com/' -P 123456 \
            -a verify -a selfsign

       Import a certificate from stdin:

          yubico-piv-tool -s 9a -a import-certificate

       Set  a  random  chuid,  import a key and import a certificate from a PKCS12 file with password test, into
       slot 9c:

          yubico-piv-tool -s 9c -i test.pfx -K PKCS12 -p test -a set-chuid \
            -a import-key -a import-cert

       Import a certificate which is larger than 2048 bytes and thus requires compression in order to fit:

         openssl x509 -in cert.pem -outform DER | gzip -9 > der.gz
         yubico-piv-tool -s 9c -i der.gz -K GZIP -a import-cert

       Change the management key used for administrative authentication:

          yubico-piv-tool -n 0807605403020108070605040302010807060504030201 \
            -a set-mgm-key

       Delete a certificate in slot 9a:

         yubico-piv-tool -a delete-certificate -s 9a

       Show some information on certificates and other data:

         yubico-piv-tool -a status

       Read out the certificate from a slot and then run a signature test:

         yubico-piv-tool -a read-cert -s 9a
         yubico-piv-tool -a verify-pin -P 123456 -a test-signature -s 9a
