根据微软帮助文档,convertto-securestring有两种加密模式。如果在指定密码的情况下,则使用aes加密,否则使用windows dpapi加密。而且aes加密也没有指明iv值与加密模式。 https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.security/convertto-securestring?view=powershell-6 ...
There are multiple ways to display date and time values with Python, however not all of them are easy to read. For example, when you collect a timestamp co
