ubuntu18.04下ssh-qt5无法FQ更新openssl之后【学习笔记】
说明：突然ssh-qt5无法使用,但是window可以正常FQ，ubuntu18.04最近却无法FQ。为什么能，应该是最近安装了什么软件导致，接口不兼容导致的，在FQ的时候却报了如下一堆的问题。
chroem浏览器报的错误:
1 ERROR:ssl_client_socket_impl.cc(1050)] handshake failed; returned -1, SSL error code 1, net_error -100
sslocal命令报的错误:

解决办法,由于最近更新了openssl，但是新版本的openssl没有使用EVP_CIPHER_CTX_cleanup接口，改用EVP_CIPHER_CTX_reset导致的:
1 sudo vim /usr/local/lib/python3.6/dist-packages/shadowsocks/crypto/openssl.py
修改如下:
重新打开ssh-qt5即可FQ成功:
