    X.509: Add a crypto key parser for binary (DER) X.509 certificates · c26fd69f
    David Howells 提交于
    Add a crypto key parser for binary (DER) encoded X.509 certificates.  The
    certificate is parsed and, if possible, the signature is verified.
    
    An X.509 key can be added like this:
    
    	# keyctl padd crypto bar @s </tmp/x509.cert
    	15768135
    
    and displayed like this:
    
    	# cat /proc/keys
    	00f09a47 I--Q---     1 perm 39390000     0     0 asymmetri bar: X509.RSA e9fd6d08 []
    
    Note that this only works with binary certificates.  PEM encoded certificates
    are ignored by the parser.
    
    Note also that the X.509 key ID is not congruent with the PGP key ID, but for
    the moment, they will match.
    
    If a NULL or "" name is given to add_key(), then the parser will generate a key
    description from the CertificateSerialNumber and Name fields of the
    TBSCertificate:
    
    	00aefc4e I--Q---     1 perm 39390000     0     0 asymmetri bfbc0cd76d050ea4:/C=GB/L=Cambridge/O=Red Hat/CN=kernel key: X509.RSA 0c688c7b []
