1=pod 2 3=head1 NAME 4 5OpenSSL_add_all_algorithms, OpenSSL_add_all_ciphers, OpenSSL_add_all_digests, EVP_cleanup - 6add algorithms to internal table 7 8=head1 SYNOPSIS 9 10 #include <openssl/evp.h> 11 12Deprecated: 13 14 # if OPENSSL_API_COMPAT < 0x10100000L 15 void OpenSSL_add_all_algorithms(void); 16 void OpenSSL_add_all_ciphers(void); 17 void OpenSSL_add_all_digests(void); 18 19 void EVP_cleanup(void) 20# endif 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. 41 42=head1 SEE ALSO 43 44L<evp(7)>, L<EVP_DigestInit(3)>, 45L<EVP_EncryptInit(3)> 46 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. 53 54=head1 COPYRIGHT 55 56Copyright 2000-2017 The OpenSSL Project Authors.
