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

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/evp.h>

       Deprecated:

        # if OPENSSL_API_COMPAT < 0x10100000L
        void OpenSSL_add_all_algorithms(void);
        void OpenSSL_add_all_ciphers(void);
        void OpenSSL_add_all_digests(void);

        void EVP_cleanup(void)
       # endif

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.
