CERTPATCH(8)            OpenBSD System Manager's Manual           CERTPATCH(8)

     certpatch - add subjectAltName identities to X.509 certificates

     certpatch [-t identity-type] -i identity -k signing-key input-certificate

     certpatch alters PEM-encoded X.509 certificates by adding a subjectAlt-
     Name extension containing an identity used by the signature-based authen-
     tication schemes of the ISAKMP protocol.  After the addition the certifi-
     cate will be signed once again with the supplied CA signing key.

     The options are as follows:

     -t identity-type
             If given, the -t option specifies the type of the given identity.
             Currently ip, fqdn, and ufqdn are recognized.  The default is ip.

     -i identity
             The -i option takes an argument which is the identity to put into
             the subjectAltName field of the certificate.  If the identity-
             type is ip, this argument should be an IPv4 address in dotted
             decimal notation.

     -k signing-key
             The -k option specifies the key used for signing the certificate
             once the subjectAltName extension has been added.  The key is
             specified by the filename where it is stored in PEM format.
