=head1 NAME
|
|
|
|
SSL_set_retry_verify - indicate that certificate verification should be retried
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
int SSL_set_retry_verify(SSL *ssl);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_set_retry_verify() should be called from the certificate verification
|
|
callback on a client when the application wants to indicate that the handshake
|
|
should be suspended and the control should be returned to the application.
|
|
L<SSL_want_retry_verify(3)> will return 1 as a consequence until the handshake
|
|
is resumed again by the application, retrying the verification step.
|
|
|
|
Please refer to L<SSL_CTX_set_cert_verify_callback(3)> for further details.
|
|
|
|
=head1 NOTES
|
|
|
|
The effect of calling SSL_set_retry_verify() outside of the certificate
|
|
verification callback on the client side is undefined.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_set_retry verify() returns 1 on success, 0 otherwise.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
The following code snippet shows how to obtain the B<SSL> object associated
|
|
with the B<X509_STORE_CTX> to call the SSL_set_retry_verify() function:
|
|
|
|
int idx = SSL_get_ex_data_X509_STORE_CTX_idx();
|
|
SSL *ssl;
|
|
|
|
/* this should not happen but check anyway */
|
|
if (idx < 0
|
|
|| (ssl = X509_STORE_CTX_get_ex_data(ctx, idx)) == NULL)
|
|
return 0;
|
|
|
|
if (/* we need to retry verification callback */)
|
|
return SSL_set_retry_verify(ssl);
|
|
|
|
/* do normal processing of the verification callback */
|
|

|
|
=head1 HISTORY
|
|
|
|
SSL_set_retry_verify() was added in OpenSSL 3.0.2 to replace backwards
|
|
incompatible handling of a negative return value from the verification
|
|
callback.
