NAME
       vfychain_ - vfychain [options] [revocation options] certfile [[options] certfile] ...

SYNOPSIS
       vfychain

STATUS
       This documentation is still work in progress. Please contribute to the initial review in
       Mozilla NSS bug 836477[1]

DESCRIPTION
       The verification Tool, vfychain, verifies certificate chains.  modutil can add and delete
       PKCS #11 modules, change passwords on security databases, set defaults, list module
       contents, enable or disable slots, enable or disable FIPS 140-2 compliance, and assign
       default providers for cryptographic operations. This tool can also create certificate,
       key, and module security database files.

       The tasks associated with security module database management are part of a process that
       typically also involves managing key databases and certificate databases.

OPTIONS
       -a
	   the following certfile is base64 encoded

       -b  YYMMDDHHMMZ
	   Validate date (default: now)

       -d  directory
	   database directory

       -f
	   Enable cert fetching from AIA URL

       -o  oid
	   Set policy OID for cert validation(Format OID.1.2.3)

       -p
	   Use PKIX Library to validate certificate by calling:

	   * CERT_VerifyCertificate if specified once,

	   * CERT_PKIXVerifyCert if specified twice and more.

       -r
	   Following certfile is raw binary DER (default)

       -t
	   Following cert is explicitly trusted (overrides db trust)

       -u  usage
	   0=SSL client, 1=SSL server, 2=SSL StepUp, 3=SSL CA, 4=Email signer, 5=Email recipient,
	   6=Object signer, 9=ProtectedObjectSigner, 10=OCSP responder, 11=Any CA

       -T
	   Trust both explicit trust anchors (-t) and the database. (Without this option, the
	   default is to only trust certificates marked -t, if there are any, or to trust the
	   database if there are certificates marked -t.)

       -v
	   Verbose mode. Prints root cert subject(double the argument for whole root cert info)

       -w  password
	   Database password

       -W  pwfile
	   Password file

	   Revocation options for PKIX API (invoked with -pp options) is a collection of the
	   following flags: [-g type [-h flags] [-m type [-s flags]] ...] ...

	   Where:

       -g  test-type
	   Sets status checking test type. Possible values are "leaf" or "chain"

       -g  test type
	   Sets status checking test type. Possible values are "leaf" or "chain".

       -h  test flags
	   Sets revocation flags for the test type it follows. Possible flags:
	   "testLocalInfoFirst" and "requireFreshInfo".

       -m  method type
	   Sets method type for the test type it follows. Possible types are "crl" and "ocsp".

       -s  method flags
	   Sets revocation flags for the method it follows. Possible types are "doNotUse",
	   "forbidFetching", "ignoreDefaultSrc", "requireInfo" and "failIfNoInfo".
