The verification Tool,
vfychain, verifies certificate chains.
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.
the following certfile is base64 encoded
Validate date (default: now)
Enable cert fetching from AIA URL
Set policy OID for cert validation(Format OID.1.2.3)
Use PKIX Library to validate certificate by calling:
* CERT_VerifyCertificate if specified once,
* CERT_PKIXVerifyCert if specified twice and more.
Following certfile is raw binary DER (default)
Following cert is explicitly trusted (overrides db trust)
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
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.)
Verbose mode. Prints root cert subject(double the argument for whole root cert info)
Revocation options for PKIX API (invoked with -pp options) is a collection of the following flags: [-g type [-h flags] [-m type [-s flags]] ...] ...
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".
