Detailed Description

Block of functions related to operations from OpenSSL.

Definition in file crypto_openssl_mgt.c.

Function Documentation

crypto_openssl_early_init()

void crypto_openssl_early_init

(

void

)

Perform early (pre-configuration) initialization tasks for OpenSSL.

Definition at line 145 of file crypto_openssl_mgt.c.

Referenced by crypto_early_init().

crypto_openssl_free_all()

static void crypto_openssl_free_all ( void  )

static

free OpenSSL variables

Definition at line 137 of file crypto_openssl_mgt.c.

Referenced by crypto_openssl_global_cleanup().

crypto_openssl_get_header_version_str()

const char * crypto_openssl_get_header_version_str

(

void

)

Definition at line 111 of file crypto_openssl_mgt.c.

crypto_openssl_get_version_str()

const char * crypto_openssl_get_version_str

(

void

)

Definition at line 96 of file crypto_openssl_mgt.c.

crypto_openssl_global_cleanup()

void crypto_openssl_global_cleanup

(

void

)

Clean up global resources held by openssl.

Definition at line 337 of file crypto_openssl_mgt.c.

crypto_openssl_init_engines()

static int crypto_openssl_init_engines ( const char *  accelName, const char *  accelDir  )

static

Initialize engines for openssl (if enabled). Load all the built-in engines, along with the one called accelName (which may be NULL). If accelName is prefixed with "!", then it is required: return -1 if it can't be loaded. Otherwise return 0.

If accelDir is not NULL, it is the path from which the engine should be loaded.

Definition at line 224 of file crypto_openssl_mgt.c.

crypto_openssl_late_init()

int crypto_openssl_late_init	(	int	useAccel,
		const char *	accelName,
		const char *	accelDir
	)

Perform late (post-init) initialization tasks for OpenSSL

Definition at line 301 of file crypto_openssl_mgt.c.

crypto_openssl_log_errors()

void crypto_openssl_log_errors	(	int	severity,
		const char *	doing
	)

Log all pending crypto errors at level severity. Use doing to describe our current activities.

Definition at line 55 of file crypto_openssl_mgt.c.

Referenced by crypto_dh_generate_public(), and new_openssl_dh_from_params().

crypto_openssl_thread_cleanup()

void crypto_openssl_thread_cleanup

(

void

)

Free crypto resources held by this thread.

Definition at line 331 of file crypto_openssl_mgt.c.

Referenced by crypto_thread_cleanup().

log_engine()

static void log_engine ( const char *  fn, ENGINE *  e  )

static

Definition at line 202 of file crypto_openssl_mgt.c.

parse_openssl_version_str()

STATIC char * parse_openssl_version_str

(

const char *

raw_version

)

Declare STATIC functions

Definition at line 76 of file crypto_openssl_mgt.c.

setup_openssl_threading()

static int setup_openssl_threading ( void  )

static

Helper: Construct mutexes, and set callbacks to help OpenSSL handle being multithreaded. Returns 0.

Definition at line 130 of file crypto_openssl_mgt.c.

Referenced by crypto_openssl_early_init().

static ENGINE * try_load_engine ( const char *  path, const char *  engine  )

static

Try to load an engine in a shared library via fully qualified path.

Definition at line 183 of file crypto_openssl_mgt.c.
