pki --keyid - Calculate key identifiers of a key or certificate

       This sub-command of pki(1) calculates key identifiers of private keys and certificates.

       Calculate key identifiers of an RSA private key:

         $ pki --keyid --in key.der
         subjkey (SHA-1 of subjectPublicKey):
                      6a:9c:74:d1:f8:89:79:89:f6:5a:94:e9:89:f1...
         keyid (SHA-1 of subjectPublicKeyInfo):
                      6e:55:dc:7e:9c:a5:58:d9:5b:e3:c7:13:14:e1...

       Calculate key identifiers of an X.509 certificate:

         $ pki --keyid --in cert.der --type x509
         subjkey (SHA-1 of subjectPublicKey):
                      6a:9c:74:d1:f8:89:79:89:f6:5a:94:e9:89:f1...
         keyid (SHA-1 of subjectPublicKeyInfo):
                      6e:55:dc:7e:9c:a5:58:d9:5b:e3:c7:13:14:e1...

       Calculate keyid in simple hex encoding of an X.509 certificate:

         $ pki --keyid --in cert.der --type x509 --id spki --format hex
         6e55dc7e9ca558d95be3c71314e1...

-h,--help
              Print usage information with a summary of the available options.

       -v,--debuglevel
              Set debug level, default: 1.

       -+,--optionsfile
              Read command line options from file.

       -i,--infile
              Input file. If not given the input is read from STDIN.

       -x,--keyidhex
              Smartcard or TPM private key object handle in hex format with an optional 0x prefix.

       -t,--typetype
              Type  of input. One of priv (private key), rsa (RSA private key), ecdsa (ECDSA private key), bliss
              (BLISS private  key),  pub  (public  key),  pkcs10  (PKCS#10  certificate  request),  x509  (X.509
              certificate), defaults to priv.

       -I,--idid-type
              Type  of  identifier.  One  of  all  (all identifiers), spk (SHA-1 hash of subjectPublicKey), spki
              (SHA-1 hash of subjectPublicKeyInfo), defaults to all.

       -f,--formatformat
              Output format. One of pretty (user-readable output), hex (hexadecimal  encoding),  base64  (Base64
              encoding), bin (raw binary data), defaults to pretty.
