How secure/anonymous is FSP?
By default, the FSP daemon keeps logs of transactions, along with their site names. An FSP administrator could use this to find out who you are, with a reasonable degree of certainty. In short, FSP gives you no more privacy than anonymous FTP. Anyone who tells you different has a less devious mind than most FSP admins I know. Why not make FSP more anonymous? Well, it’s impossible to make a protocol with complete anonymity, since at some point, the remote site will have to send a file back to you, and it needs at least an address to send it to. If you really need privacy, you can encrypt any files you make available, and only give out the decryption password to a select few. But of course, you have to trust them to keep the password safe.
