Powershell and Secure/Encrypted strings

Hey there!

Sometimes you may have a need to encode or encrypt a string. This is usually neccessary for strings like passwords.

Let’s start with creating an encrypted string:

$password = "MostSecureOne123"

# Convert password to Secure String
$password_SecureString = ConvertTo-SecureString -String $password -AsPlainText -Force

# Convert a secure string to an encrypted string
$password_EncryptedString = ConvertFrom-SecureString $password_SecureString

Good, this can be now saved or further manipulated.

When you need to decrypt the string, use following:

# Convert from Encrypted string to Secure string
$password_SecureString = ConvertTo-SecureString -String $password_EncryptedString

# Convert from Secure string to plain text
$Credentials = New-Object System.Management.Automation.PSCredential -ArgumentList $env:username,$password_SecureString

$PlainPassword = $Credentials.GetNetworkCredential().Password

# Here it is!


Let me know whether this was useful to you, or not.
