(PowerShell) Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password) ) )

Demonstrates how to compute:

Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password)))

# First SHA-1 digest the password...

# Append the 20 binary bytes of the SHA1 hash to bd, which already contains the nonce and created date/time.
