hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,

=head1 DESCRIPTION
|
|
|
|
|
|
|
|
OpenSSL keeps an internal table of digest algorithms and ciphers. It uses
|
2017-09-02 21:35:50 +08:00
|
|
|
this table to lookup ciphers via functions such as EVP_get_cipher_byname().
|
2000-02-23 22:27:47 +08:00
|
|
|
|
|
|
|
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.
|
|
|
|
|
2016-04-04 22:28:58 +08:00
|
|
|
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.

None of the functions return a value.
