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>

       The following functions have been deprecated since OpenSSL 1.1.0, and 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.

SEE ALSO

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.
