Symbols count in article: 4.5k Reading time ≈ 4 mins.

核心 API:SSL_CTX_set_cipher_list(SSL_CTX *,const char *str)

API

#include <openssl/ssl.h>

int SSL_CTX_set_cipher_list(SSL_CTX *ctx, const char *str);
int SSL_set_cipher_list(SSL *ssl, const char *str);

用于在Client_hello中提交一份自己能够支持的加密方法的列表,由服务端选择一种方法后在Server_Hello中通知服务端, 从而完成加密算法的协商。

因此需要禁用某些指定的算法，只需要将它从列表中删除即可。

默认密钥

version:openssl 1.0.2-stable头文件ssl.h中定义
# define SSL_DEFAULT_CIPHER_LIST "ALL:!EXPORT:!LOW:!aNULL:!eNULL:!SSLv2"
可以使用命令openssl ciphers查看所有密钥套件

command

$ openssl ciphers -v
$ openssl ciphers -v 'ALL'
$ openssl ciphers -v 'ALL:!NULL-MD5:!NULL-SHA!AES'
$ openssl ciphers -v 'HIGH:!ADH:!MD5:!RC4:!SRP:!PSK:!DSS'

$ openssl ciphers -v 'HIGH:!ADH:!MD5:!RC4:!SRP:!PSK:!DSS'
