This encryption software needs to:

  • run on Windows
  • install a mail proxy that would run locally
  • allow you to select the strength of your key up to 10240 bits
  • has a one-use scratchpad for entropy
  • possibly be made in Australia
  • allow you to exchange keys through mail as well (not recommended)

Does anyone recall the name of the encryption software made in Australia, popular in the early 2000s? I can't recall the name for the life of me. The software was called something like mail-crypt or crypt-mail or secure-mail or mail-secure.
