SYNOPSIS
/* -lcrypto */

void
OpenSSL_add_all_algorithms(void);

EVP_cleanup(void);
void
SSLeay_add_all_algorithms(void);
DESCRIPTION
These functions are deprecated. It is never useful for any application program to call any of them explicitly. Most of them have no effect except that they may or may not call OPENSSL_init_crypto(3).
The library contains internal tables of digest algorithms and ciphers. It uses these tables to look up digests and ciphers via EVP_get_digestbyname(3) and EVP_get_cipherbyname(3), respectively. In LibreSSL, these tables are static constants and do not require initialization.
OpenSSL_add_all_algorithms()
used to add all digests and ciphers to the tables. If an application is
compiled with the preprocessor symbol
OPENSSL_LOAD_CONF defined, it also calls
OPENSSL_config(3) with a NULL argument,
loading the default configuration file. Relying on this behaviour is not
recommended. If loading a configuration file is desired, call
OPENSSL_config(3) or
CONF_modules_load_file(3) directly.
OpenSSL_add_all_digests()
used to add all digest algorithms to the table.
OpenSSL_add_all_ciphers()
used to add all encryption algorithms to the table.
EVP_cleanup()
has no effect; it used to remove various kinds of application-supplied data
that is no longer supported in the first place.
SSLeay_add_all_algorithms()
is a deprecated alias for
OpenSSL_add_all_algorithms().
OpenSSL_add_all_algorithms()
and SSLeay_add_all_algorithms() are implemented as
macros.

BUGS
Although the functions do not return error codes, it is possible for them to fail.
