在linux中存储凭据

Question

我需要访问一个需要用户名和密码的服务，我不希望将此存储在代码中。代码在带有kerberos的linux服务器上运行。在

有谁能举出一些例子，让我用python或linux的bashshell在linux上存储密码？在

目前我在一个只有当前用户权限的文件中使用明文密码。在

有人给我指出了一个使用powershell的指南：

#

#The following command create a txt file containing a encrypted version of
#the password string (in this example "P@ssword1"). This is something you do once while
#logged on as the account that will eventually decrypt the password
#######################################################################################
"P@ssword1" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "C:\Temp\Password.txt"


#######################################################################################
#In your script that are using the encrypted password, you can do the following:
#######################################################################################
# 1) Read the encrypted password from the txt file and convert it to a SecureString object
$pass = Get-Content "C:\Temp\Password.txt" | ConvertTo-SecureString

# 2) Convert the SecureString object to a plain text variable that can be used in the script
#The decrypted password is now available in the $UnsecurePassword variable.
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass)
$UnsecurePassword = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)
cls
Write-Host $UnsecurePassword
