8=head1 SYNOPSIS
9
10 #include <openssl/evp.h>
11
12The following functions have been deprecated since OpenSSL 1.1.0, and can be
13hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
14see L<openssl_user_macros(7)>:
15
16 void OpenSSL_add_all_algorithms(void);
17 void OpenSSL_add_all_ciphers(void);
18 void OpenSSL_add_all_digests(void);
19
20 void EVP_cleanup(void);
21
22=head1 DESCRIPTION
23
24OpenSSL keeps an internal table of digest algorithms and ciphers. It uses
25this table to lookup ciphers via functions such as EVP_get_cipher_byname().
26
27OpenSSL_add_all_digests() adds all digest algorithms to the table.
28
29OpenSSL_add_all_algorithms() adds all algorithms to the table (digests and
30ciphers).
31
32OpenSSL_add_all_ciphers() adds all encryption algorithms to the table including
33password based encryption algorithms.
34
35In versions prior to 1.1.0 EVP_cleanup() removed all ciphers and digests from
36the table. It no longer has any effect in OpenSSL 1.1.0.
37
38=head1 RETURN VALUES
39
40None of the functions return a value.

47=head1 HISTORY
48
49The OpenSSL_add_all_algorithms(), OpenSSL_add_all_ciphers(),
50OpenSSL_add_all_digests(), and EVP_cleanup(), functions
51were deprecated in OpenSSL 1.1.0 by OPENSSL_init_crypto() and should
52not be used.
