Create a secure string by typing at the command prompt.

PS C:\> $securestring = read-host -asSecureString

Convert a secure string stored in a variable to an encrypted standard string. The resulting encrypted standard string can be displayed by typing $standardstring:

PS C:\> $my_encrypted_string = Convertfrom-SecureString $securestring

Convert a secure string using the Rijndael algorithm, the key is an array of 24 digits, all of which are less than 256, (24 * 8 bit bytes = 192 bits)

PS C:\> $key = (3,42,2,3,100,34,254,222,1,1,2,23,42,54,33,233,1,64,2,7,6,5,35,43)
PS C:\> $standardstring = convertfrom-securestring $securestring -key $key
