    skos:definition "Identifier of a public key in the subjectKeyIdentifier and authorityKeyIdentifier extensions of an X.509 certificate. It links a certificate to the certificate of its issuer and to revocation lists. RFC 5280 suggests the 160-bit SHA-1 of the public key (20 octets) or a 64-bit form of it (8 octets), and allows other methods. The regexp covers the 20- and 8-octet forms in hexadecimal, compact or with colons. The compact 20-octet form looks like a SHA-1 hash: the type is told by the field name."@en ;
