Encryption Process The credentials are acquired from the user via prompt as a SecureString (System.Security.SecureString). Using the PowerShell function ConvertFrom-SecureString, the password portion of this secure string is encrypted with AES using a 256 bit key. This key is contained in Security.psm1 and can be modified.

Example 1: Create a secure string PowerShell Copy $SecureString = Read-Host -AsSecureString This command creates a secure string from characters that you type at the command prompt. After entering the command, type the string you want to store as a secure string. An asterisk ( *) is displayed to represent each character that you type. I have given simple examples of these two methods below. Method 1 (Using Secure String): #Plain Text Password $Password = "password" $Key = @ (1..32) #Convert Password to a secure string $SecureString = ConvertTo-SecureString -AsPlainText -Force -String $Password #Convert SecureString to an encrypted string using the encryption key. PowerShell has a handy cmdlet aptly named ConvertFrom-SecureStringwith the following syntax, ConvertFrom-SecureString-SecureString$secStringPassword, The above will produce an encryptedstandard string, I have described this process in my post about storing credentials in a script, which is not what we're looking for.
