NAME

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

SYNOPSIS

[--in file|--keyid hex] [ --type type ] [ --id id-type ] [ --format format ] [ --debug level ] --options~file -h | --help

DESCRIPTION

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

OPTIONS

-h, --help: Print usage information with a summary of the available options.
-v, --debug level: Set debug level, default: 1.
-+, --options file: Read command line options from file.
-i, --in file: Input file. If not given the input is read from STDIN.
-x, --keyid hex: Smartcard or TPM private key object handle in hex format with an optional 0x prefix.
-t, --type type: 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, --id id-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, --format format: Output format. One of pretty (user-readable output), hex (hexadecimal encoding), base64 (Base64 encoding), bin (raw binary data), defaults to pretty.

EXAMPLES

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
