.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "X509_STORE_CTX_NEW 3"
way too many mistakes in technical documents.
\fBX509_STORE_CTX_new() returns a newly initialised X509_STORE_CTX structure.
\fBX509_STORE_CTX_cleanup() internally cleans up an X509_STORE_CTX structure. The context can then be reused with a new call to X509_STORE_CTX_init().
\fBX509_STORE_CTX_free() completely frees up ctx. After this call ctx is no longer valid. If ctx is \s-1NULL\s0 nothing is done.
\fBX509_STORE_CTX_init() sets up ctx for a subsequent verification operation. It must be called before each call to X509_verify_cert(), i.e. a ctx is only good for one call to X509_verify_cert(); if you want to verify a second certificate with the same ctx then you must call X509_STORE_CTX_cleanup() and then X509_STORE_CTX_init() again before the second call to \fBX509_verify_cert(). The trusted certificate store is set to store, the end entity certificate to be verified is set to x509 and a set of additional certificates (which will be untrusted but may be used to build the chain) in \fBchain. Any or all of the store, x509 and chain parameters can be \fB\s-1NULL\s0.
\fBX509_STORE_CTX_set0_trusted_stack() sets the set of trusted certificates of \fBctx to sk. This is an alternative way of specifying trusted certificates instead of using an X509_STORE.
\fBX509_STORE_CTX_set_cert() sets the certificate to be verified in ctx to \fBx.
\fBX509_STORE_CTX_set0_verified_chain() sets the validated chain used by ctx to be chain. Ownership of the chain is transferred to ctx and should not be free'd by the caller. \fBX509_STORE_CTX_get0_chain() returns the internal pointer used by the \fBctx that contains the validated chain.
\fBX509_STORE_CTX_set0_crls() sets a set of CRLs to use to aid certificate verification to sk. These CRLs will only be used if \s-1CRL\s0 verification is enabled in the associated X509_VERIFY_PARAM structure. This might be used where additional \*(L"useful\*(R" CRLs are supplied as part of a protocol, for example in a PKCS#7 structure.
\fBX509_STORE_CTX_get0_param() retrieves an internal pointer to the verification parameters associated with ctx.
\fBX509_STORE_CTX_get0_untrusted() retrieves an internal pointer to the stack of untrusted certificates associated with ctx.
\fBX509_STORE_CTX_set0_untrusted() sets the internal point to the stack of untrusted certificates associated with ctx to sk.
\fBX509_STORE_CTX_set0_param() sets the internal verification parameter pointer to param. After this call param should not be used.
\fBX509_STORE_CTX_set_default() looks up and sets the default verification method to name. This uses the function X509_VERIFY_PARAM_lookup() to find an appropriate set of parameters from name.
\fBX509_STORE_CTX_get_num_untrusted() returns the number of untrusted certificates that were used in building the chain following a call to X509_verify_cert().
\fBX509_STORE_CTX_set_verify() provides the capability for overriding the default verify function. This function is responsible for verifying chain signatures and expiration times.
A verify function is defined as an X509_STORE_CTX_verify type which has the following signature:
.Vb 1 int (*verify)(X509_STORE_CTX *); .Ve
This function should receive the current X509_STORE_CTX as a parameter and return 1 on success or 0 on failure.
\fBX509_STORE_CTX_init() returns 1 for success or 0 if an error occurred.
\fBX509_STORE_CTX_get0_param() returns a pointer to an X509_VERIFY_PARAM structure or \s-1NULL\s0 if an error occurred.
\fBX509_STORE_CTX_cleanup(), X509_STORE_CTX_free(), \fBX509_STORE_CTX_set0_trusted_stack(), \fBX509_STORE_CTX_set_cert(), \fBX509_STORE_CTX_set0_crls() and X509_STORE_CTX_set0_param() do not return values.
\fBX509_STORE_CTX_set_default() returns 1 for success or 0 if an error occurred.
\fBX509_STORE_CTX_get_num_untrusted() returns the number of untrusted certificates used.
