The self tests for the fips module are triggered on startup and they need to know the core's libctx in order to function correctly. As the provider can be autoloaded via configuration it then needs to propagate the callers libctx down to the provider via the config load. Note that OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CONFIG, ..) is still called, but will only load the default configuration if the OPENSSL_CONF environment variable is set.

=head1 NAME

|
|
OPENSSL_CTX, OPENSSL_CTX_new, OPENSSL_CTX_free, OPENSSL_CTX_load_config
|
|
- OpenSSL library context
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/crypto.h>
|
|
|
|
typedef struct openssl_ctx_st OPENSSL_CTX;
|
|
|
|
OPENSSL_CTX *OPENSSL_CTX_new(void);
|
|
int OPENSSL_CTX_load_config(OPENSSL_CTX *ctx, const char *config_file);
|
|
void OPENSSL_CTX_free(OPENSSL_CTX *ctx);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
C<OPENSSL_CTX> is an internal OpenSSL library context type.
|
|
Applications may allocate their own, but may also use C<NULL> to use
|
|
the internal default context with functions that take a C<OPENSSL_CTX>
|
|
argument.
|
|
|
|
OPENSSL_CTX_new() creates a new OpenSSL library context.
|
|
When a non default library context is in use care should be taken with
|
|
multi-threaded applications to properly clean up thread local resources before
|
|
the OPENSSL_CTX is freed.
|
|
See L<OPENSSL_thread_stop_ex(3)> for more information.
|
|
|
|
OPENSSL_CTX_load_config() loads a configuration file using the given C<ctx>.
|
|
This can be used to associate a libctx with providers that are loaded from
|
|
a configuration.
|
|
|
|
OPENSSL_CTX_free() frees the given C<ctx>.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
OPENSSL_CTX_new() return a library context pointer on success, or
|
|
C<NULL> on error.
|
|
|
|
OPENSSL_CTX_free() doesn't return any value.
|
|
|
|
=head1 HISTORY
|
|
|
|
OPENSSL_CTX, OPENSSL_CTX_new(), OPENSSL_CTX_load_config() and OPENSSL_CTX_free()
|
|
were added in OpenSSL 3.0.
