OPENSSL_ADD_ALL_ALGORITHMS(3)

NAME
OpenSSL_add_all_algorithms, OpenSSL_add_all_ciphers, OpenSSL_add_all_digests, EVP_cleanup - add algorithms to internal table

SYNOPSIS
 #include <openssl/evp.h>

Deprecated since OpenSSL 1.1.0, can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):

 void OpenSSL_add_all_algorithms(void);
 void OpenSSL_add_all_ciphers(void);
 void OpenSSL_add_all_digests(void);

 void EVP_cleanup(void);

DESCRIPTION
OpenSSL keeps an internal table of digest algorithms and ciphers. It uses this table to lookup ciphers via functions such as EVP_get_cipher_byname().

OpenSSL_add_all_digests() adds all digest algorithms to the table.

OpenSSL_add_all_algorithms() adds all algorithms to the table (digests and ciphers).

OpenSSL_add_all_ciphers() adds all encryption algorithms to the table including password based encryption algorithms.

In versions prior to 1.1.0 EVP_cleanup() removed all ciphers and digests from the table. It no longer has any effect in OpenSSL 1.1.0.

RETURN VALUES
None of the functions return a value.

HISTORY
The OpenSSL_add_all_algorithms(), OpenSSL_add_all_ciphers(), OpenSSL_add_all_digests(), and EVP_cleanup(), functions were deprecated in OpenSSL 1.1.0 by OPENSSL_init_crypto() and should not be used.
