Subject: [PATCH] Remove API deprecated in openssl 1.1
|
|
|
|
With openssl 1.1, we do not call OpenSSL_add_all_algorithms(), as
|
|
library initialization is done automatically.
|
|
Functions RAND_pseudo_bytes and RSA_generate_key were deprecated as
|
|
well.
|
|
Also, we need to #include <openssl/bn.h> for BN_num_bytes().
|
|
