=head1 NAME
OpenSSL_add_all_algorithms, OpenSSL_add_all_ciphers, OpenSSL_add_all_digests, EVP_cleanup -
add algorithms to internal table
=head1 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
=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().
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.
=head1 RETURN VALUES
None of the functions return a value.
=head1 SEE ALSO
L<evp(7)>, L<EVP_DigestInit(3)>,
L<EVP_EncryptInit(3)>
=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() and should
not be used.
