Security Considerations
=======================
When using Wget, you must be aware that it sends unencrypted
passwords through the network, which may present a security problem.
Here are the main issues, and some solutions.
1. The passwords on the command line are visible using `ps'. The
best way around it is to use `wget -i -' and feed the URLs to
Wget's standard input, each on a separate line, terminated by
`C-d'. Another workaround is to use `.netrc' to store passwords;
however, storing unencrypted passwords is also considered a
security risk.
2. Using the insecure "basic" authentication scheme, unencrypted
passwords are transmitted through the network routers and gateways.
3. The FTP passwords are also in no way encrypted. There is no good
solution for this at the moment.
4. Although the "normal" output of Wget tries to hide the passwords,
debugging logs show them, in all forms. This problem is avoided by
being careful when you send debug logs (yes, even when you send
them to me).
