NAME

     certpatch -- add subjectAltName identities to X.509 certificates

SYNOPSIS

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

DESCRIPTION

     certpatch alters PEM-encoded X.509 certificates by adding a subjectAltName extension containing an identity used by the signature-based
     authentication schemes of the ISAKMP protocol.  After the addition the certificate 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 speci-
	     fied by the filename where it is stored in PEM format.
