使用 Python 生成私人/public SSH 密钥
Generate private / public SSH key with Python
我只需要用 Python 创建一个 private/public 密钥对。
我想获得与以下 ssh-keygen
命令相同的结果:
ssh-keygen -t rsa -b 4096 -C "sample.key" -N "" -f "key" && mv "key" "key.opk"
生成以下内容:
key.opk

但我还需要 public 密钥。
您这样做是为了获取私钥:
print crypto.dump_privatekey(crypto.FILETYPE_PEM, k)
执行 this 以获得 public 密钥:
print crypto.dump_<b>public</b>key(crypto.FILETYPE_PEM, k)
最简单的方法是使用Paramiko library。使用
安装
pip3 install paramiko
(或 "pip install paramiko",如果使用 python2)考虑这个简短的例子。
import sys
import paramiko
key = paramiko.RSAKey.generate(4096)
print(key.get_base64()) # print public key
key.write_private_key(sys.stdout) # print private key
我只需要用 Python 创建一个 private/public 密钥对。
我想获得与以下 ssh-keygen
命令相同的结果:
ssh-keygen -t rsa -b 4096 -C "sample.key" -N "" -f "key" && mv "key" "key.opk"
生成以下内容:

到目前为止,我有以下 Python 代码:
from OpenSSL import crypto
k = crypto.PKey()
k.generate_key(crypto.TYPE_RSA, 4096)
print crypto.dump_privatekey(crypto.FILETYPE_PEM, k)

但我还需要 public 密钥。
您这样做是为了获取私钥:
print crypto.dump_privatekey(crypto.FILETYPE_PEM, k)
执行 this 以获得 public 密钥:
print crypto.dump_<b>public</b>key(crypto.FILETYPE_PEM, k)
最简单的方法是使用Paramiko library。使用
安装pip3 install paramiko
(或 "pip install paramiko",如果使用 python2)考虑这个简短的例子。
import sys
import paramiko
key = paramiko.RSAKey.generate(4096)
print(key.get_base64()) # print public key
key.write_private_key(sys.stdout) # print private key
