ConvertFrom-SecureString - Powershell 2.0 CmdLet

Microsoft Windows PowerShell is a command-line shell and scripting tool based on the Microsoft .NET Framework. It is designed for system administrators, engineers and developers to control and automate the administration of Windows and applications.

More than hundred command-line tools (so called "cmdlets") can be used to perform system administration tasks and Windows Management Instrumentation (WMI). These cmdlets are easy to use, with standard naming conventions and common parameters, and standard tools for piping, sorting, filtering, and formatting data and objects.

ConvertFrom-SecureString

---

Short description
Converts a secure string into an encrypted standard string.

Syntax
ConvertFrom-SecureString [-Key <Byte[]>] [-SecureString] <SecureString> [<CommonParameters>]
    
    ConvertFrom-SecureString [[-SecureKey] <SecureString>] [-SecureString] <SecureString> [<CommonParameters>]

Description
The ConvertFrom-SecureString cmdlet converts a secure string (System.Security.SecureString) into an encrypted stand
    ard string (System.String). Unlike a secure string, an encrypted standard string can be saved in a file for later u
    se. The encrypted standard string can be converted back to its secure string format by using the ConvertTo-SecureSt
    ring cmdlet. If an encryption key is specified by using the Key or SecureKey parameters, the Rijndael encryption al
    gorithm is used. The specified key must have a length of 128, 192, or 256 bits because those are the key lengths su
    pported by the Rijndael encryption algorithm. If no key is specified, the Windows Data Protection API (DPAPI) is us
    ed to encrypt the standard string representation.
