安装python3

安装依赖：
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel lzma xz-devel libffi-devel gcc make
因下载源码包很慢，需要使用proxy：
export https_proxy=socks5://192.168.72.1:1080
下载源码：
curl https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz -o Python-3.7.2.tar.xz
解压：
tar xf Python-3.7.2.tar.xz
安装：
./configure --prefix=/usr/local/python3
make && make install
导出PATH
export PATH=$PATH:/usr/local/python3/bin
python3 -V

SecureCRT

因为使用了proxy，需要安装pysocks
unset https_proxy
pip3 install pysocks
export https_proxy=socks5://192.168.72.1:1080
pip3 install pycryptodome
curl -O https://raw.githubusercontent.com/DoubleLabyrinth/how-does-SecureCRT-encrypt-password/master/python3/SecureCRTCipher.py
