You may choose between two (incompatible) hash methods:

  • HMAC-SHA1 (default)
    The formula is (secret,alias) → HMAC_SHA1 → BASE64
  • simple SHA1 (default for upgraders)
    The formula is "[secret][alias]" → SHA1 → BASE64

You may choose between the following destinations for your password:

  • Primary Selection (paste using middle mouse button)
  • Clipboard (paste using Ctrl+V)
  • Additional Copy Notification without password
