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:

        # 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.
