.Sh DESCRIPTION
These functions operate on the
.Vt X509_VERIFY_PARAM
object used by
.Fa ctx .
Usually,
.Xr X509_STORE_CTX_init 3
is called on
.Fa ctx
before these functions, and
.Xr X509_verify_cert 3
afterwards.
.Pp
.Fn X509_STORE_CTX_set_flags
sets the internal verification parameter flags to
.Fa flags .
See
.Xr X509_VERIFY_PARAM_set_flags 3
for a description of the verification flags.
.Pp
.Fn X509_STORE_CTX_set_time
sets the verification
.Fa time .
The
.Fa dummy
argument is ignored.
.Pp
.Fn X509_STORE_CTX_set_depth
sets the maximum verification
.Fa depth .
That is the maximum number of untrusted CA certificates
that can appear in a chain.
.Pp
.Fn X509_STORE_CTX_get0_param
retrieves an internal pointer to the verification parameters associated
with
.Fa ctx .
.Pp
.Fn X509_STORE_CTX_set0_param
sets the internal verification parameter pointer to
.Fa param .
After this call
.Fa param
should not be used.
.Pp
.Fn X509_STORE_CTX_set_default
looks up and sets the default verification method to
.Fa name .
This uses the function
.Xr X509_VERIFY_PARAM_lookup 3
to find an appropriate set of parameters from
.Fa name .
.Sh RETURN VALUES
.Fn X509_STORE_CTX_get0_param
returns a pointer to an
.Vt X509_VERIFY_PARAM
structure or
.Dv NULL
if an error occurred.
.Pp
.Fn X509_STORE_CTX_set_default
returns 1 for success or 0 if an error occurred.
