Python子进程问题

我正在编写一个脚本来用 Python 生成 CSR。脚本非常简单。我使用以下命令生成 RSA 私钥：

keycmd = "openssl genrsa -out mykey.pem 2048"
keyprocess = Popen(keycmd, shell=True, stdout=PIPE)

csrcmd = "openssl req -new -key mykey.pem -subj "+ subj + " -out mycsr.csr"
reqprocess = Popen(csrcmd, shell=True, stdout=PIPE)

但是，我想添加用户期望的使用密码加密私钥的功能。这通常是通过在 genrsa 命令中包含选项“-des3”来完成的，但我不知道如何将字符串从 Python 标准输入传输到 OpenSSL 进程。任何帮助将不胜感激。

我想做的是：

keycmd = "openssl genrsa -des3 -out mykey.pem 2048"
keyprocess = Popen(keycmd, shell=True, stdin=PIPE, stdout=PIPE)
keyprocess.communicate("password")
keyprocess.communicate("password")

但是它不起作用，脚本只是冻结并且永远不会超过第一个通信语句。

I'm writing a script to generate a CSR in Python. The script is very simple. I generate an RSA private key by using the following:

keycmd = "openssl genrsa -out mykey.pem 2048"
keyprocess = Popen(keycmd, shell=True, stdout=PIPE)

csrcmd = "openssl req -new -key mykey.pem -subj "+ subj + " -out mycsr.csr"
reqprocess = Popen(csrcmd, shell=True, stdout=PIPE)

However, I want to add the functionality to encrypt the private key with a password is the user desires. This is normally done by including the option "-des3" in the genrsa command, but I don't know how to pipe a string from Python standard input to the OpenSSL process. Any help would be appreciated.

What I want to do is:

keycmd = "openssl genrsa -des3 -out mykey.pem 2048"
keyprocess = Popen(keycmd, shell=True, stdin=PIPE, stdout=PIPE)
keyprocess.communicate("password")
keyprocess.communicate("password")

It's not working however, the script just freezes and never gets past the first communicate statement.

将选项 -passout stdin 添加到 openssl genrsa 命令，它将从标准输入读取密码。这应该允许您通过communicate发送它。

您可以向 -passout 选项提供其他几个值，以从其他来源获取密码。有关详细信息，请参阅 OpenSSL 手册页。

您是否尝试过 Pexpect 模块？

import pexpect

child = pexpect.spawn(keycmd)
child.expect("Enter pass phrase")
child.sendline("password")

child.expect("Verifying - Enter pass phrase")
child.sendline("password")

Have you tried the Pexpect module ?

import pexpect

child = pexpect.spawn(keycmd)
child.expect("Enter pass phrase")
child.sendline("password")

child.expect("Verifying - Enter pass phrase")
child.sendline("password")
