X509_verify_cert

Section: OpenSSL (3)
Updated: 2015-01-20
Index Return to Main Contents
 

NAME

X509_verify_cert - discover and verify X509 certificte chain  

SYNOPSIS

 #include <openssl/x509.h>

 int X509_verify_cert(X509_STORE_CTX *ctx);

 

DESCRIPTION

The X509_verify_cert() function attempts to discover and validate a certificate chain based on parameters in ctx. A complete description of the process is contained in the verify(1) manual page.  

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 ctx using, for example X509_STORE_CTX_get_error().  

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 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.  

BUGS

This function uses the header x509.h as opposed to most chain verification functiosn which use x509_vfy.h.  

SEE ALSO

X509_STORE_CTX_get_error(3)  

HISTORY

X509_verify_cert() is available in all versions of SSLeay and OpenSSL.
