本文适用于解决openssl升级到1.1.0以上版本,导致shadowsocks2.8.2启动报undefined symbol: EVP_CIPHER_CTX_cleanup错误。
最近将kali升级到了最新版本,编译之后shadowsocks无法启动,报错如下:

AttributeError: /usr/lib/x86_64-Linux-gnu/libcrypto.so.1.1: undefined symbol: EVP_CIPHER_CTX_cleanup
这个问题是由于在openssl1.1.0版本中,废弃了EVP_CIPHER_CTX_cleanup函数,如官网中所说:
EVP_CIPHER_CTX was made opaque in OpenSSL 1.1.0. As a result, EVP_CIPHER_CTX_reset() appeared and EVP_CIPHER_CTX_cleanup() disappeared.
EVP_CIPHER_CTX_init() remains as an alias for EVP_CIPHER_CTX_reset().
修改方法:
- 用vim打开文件:vim /usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py (该路径请根据自己的系统情况自行修改,如果不知道该文件在哪里的话,可以使用find命令查找文件位置)
- 跳转到52行(shadowsocks2.8.2版本,其他版本搜索一下cleanup)
- 进入编辑模式
- 将第52行libcrypto.EVP_CIPHER_CTX_cleanup.argtypes = (c_void_p,)
改为libcrypto.EVP_CIPHER_CTX_reset.argtypes = (c_void_p,) - 再次搜索cleanup(全文件共2处,此处位于111行),将libcrypto.EVP_CIPHER_CTX_cleanup(self._ctx)
改为libcrypto.EVP_CIPHER_CTX_reset(self._ctx) - 保存并退出
- 启动shadowsocks服务:service shadowsocks start 或 sslocal -c ss配置文件目录
- 问题解决
