| +=head1 NAME
|
| +
|
| +X509_verify_cert - discover and verify X509 certificte chain
|
| +
|
| +=head1 SYNOPSIS
|
| +
|
| + #include <openssl/x509.h>
|
| +
|
| + int X509_verify_cert(X509_STORE_CTX *ctx);
|
| +
|
| +=head1 DESCRIPTION
|
| +
|
| +The X509_verify_cert() function attempts to discover and validate a
|
| +certificate chain based on parameters in B<ctx>. A complete description of
|
| +the process is contained in the L<verify(1)|verify(1)> manual page.
|
| +
|
| +=head1 RETURN VALUES
|
| +
|
| +If a complete chain can be built and validated this function returns 1,
|
| +otherwise it return zero, in exceptional circumstances it can also
|
| +return a negative code.
|
| +
|
| +If the function fails additional error information can be obtained by
|
| +examining B<ctx> using, for example X509_STORE_CTX_get_error().
|
| +
|
| +=head1 NOTES
|
| +
|
| +Applications rarely call this function directly but it is used by
|
| +OpenSSL internally for certificate validation, in both the S/MIME and
|
| +SSL/TLS code.
|
| +
|
| +The negative return value from X509_verify_cert() can only occur if no
|
| +certificate is set in B<ctx> (due to a programming error) or if a retry
|
| +operation is requested during internal lookups (which never happens with
|
| +standard lookup methods). It is however recommended that application check
|
| +for <= 0 return value on error.
|
| +
|
| +=head1 BUGS
|
| +
|
| +This function uses the header B<x509.h> as opposed to most chain verification
|
| +functiosn which use B<x509_vfy.h>.
