NAME

       ipsec-algparse - utility for verifying IKE and IPsec cryptographic proposal syntax

SYNOPSIS

       ipsec algparse [-v1 | -v2 | -v | -verbose | -debug | -p1 | -p2 | -pfs {yes | no} | -fips {yes | no} |
                      -ignore | -impair | -nsspw password]
                      {-tp | -ta | ike=proposals | esp=proposals | ah=proposals | proposals}

DESCRIPTION

       ipsec algparse is a utility that parses and expands and Internet Key Exchange cryptographic proposals
       using the same syntax as used in the file ipsec.conf (see the description of ike= and esp= in
       ipsec.conf(5) for details). In addition, ipsec algparse can be used to run the proposal parser or the
       cryptographic algorithm testsuites.

       The following options control what ipsec algparse will parse:

       ike=[proposals], esp=[proposals], ah=[proposals]
           Parse the proposals using the IKE, ESP, or AH proposal parser. When proposals is omitted, display the
           default IKE, ESP, or AH proposals.

       proposal
           Try to parse the proposal using all three of the IKE, ESP, and AH proposal parsers.

       -tp
           run the proposal testsuite

       -ta
           run the algorithm testsuite

       The following options alter the parser behaviour:

       -v1, -v2
           Parse the proposals using either the IKEv1 or IKEv2 proposal syntax.

           The default is IKEv2.

       -pfs=yes|no
           Specify PFS (Perfect Forward Privicy). When yes Diffi-Helman algorithms will be included in the
           proposal.

           The default is --pfs=no.

       -fips=yes|no
           Force NSS into FIPS mode.

           The default is determined by the system environment.

       -p1, -p2
           Specify the parser to use.

           By default, IKEv1 uses the simple (p1) parser, and IKEv2 uses the more complex (p2) parser.

       -nsspw
           Specify the NSS database password.

       -impair
           Impair the parser, disabling all algorithm checks.

       -ignore
           Ignore parser errors.

       -v, -verbose
           Be more verbose when invoking proposal parser.

       -d, -debug
           Enable full debug-logging when invoking the proposal parser.
