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 specified by the filename where it is stored in PEM format.
