如何通过ssh将加密密码从一个脚本传递到另一个脚本？

Question

我正在尝试编写一个读取本地PC上的凭证文件的迷你脚本，该脚本使用用户/密码作为参数调用远程计算机上的另一个脚本。我在远程机器上使用Fabric2来ssh。这一切都有效，但我不想像现在那样将凭证作为明文发送。我希望它尽可能安全，因为我想在生产中实现它。有什么建议吗？

如果我运行ps -ef |，那么最大的问题就是在远程服务器上grep py我看到两个用户名/密码清除为这样的参数：

armkreuz 6780 6779 0 15:11？ 00:00:00 /usr/bin/python3.6 /home/armkreuz/scripts/test_password.py [email protected] test123

#Local script
from os.path import expanduser,isfile
from getpass import getpass
import sys
home = expanduser('~')
from fabric import Connection

if not isfile(f"{home}\AppData\Roaming\comcast_credential"):
    user = input('Enter your email adress: ')
    password = getpass("Enter your password: ")
    with open(f"{home}\AppData\Roaming\comcast_credential", 'w') as cred_file:
        cred_file.write(f"{user}\n")
        cred_file.write(password)
else:
    with open(f"{home}\AppData\Roaming\comcast_credential") as cred_file:
        user=cred_file.readline().rstrip('\n')
        password=cred_file.readline()

conn = Connection('[email protected]')


if user == "" or password == "":
    print("No user or password")
    exit(0)
print(f"User = {user}")
print(f"Password = {password}")



conn.run(f"/home/armkreuz/scripts/test_password.py {user} {password}")


#Remote script
import sys
from time import sleep

user = sys.argv[1]
password = sys.argv[2]

with open('test.txt', 'w') as file:
        file.write(f"User = {user}\n")
        file.write(f"Password = {password}")


for x in range(1000):
    print(x)
sleep(10)
