=head1 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().
+this table to lookup ciphers via functions such as EVP_get_cipher_byname(). In
+OpenSSL versions prior to 1.1.0 these functions initialised and de-initialised
+this table. From OpenSSL 1.1.0 they are deprecated. No explicit initialisation
+or de-initialisation is required. See L<OPENSSL_init_crypto(3)> for further
+information.
OpenSSL_add_all_digests() adds all digest algorithms to the table.
OpenSSL_add_all_ciphers() adds all encryption algorithms to the table including
password based encryption algorithms.
-EVP_cleanup() removes all ciphers and digests from the table.
+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.

+=head1 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().
