How can clients easily and securely send me passwords?
I often need to get passwords from clients for FTP, SSH, MySQL, Authorize.net, etc.
What's an easy way for them to send me passwords securely? Maybe even without them needing a login/password?
Ideal: An easy way for non-tech-savvy people to send encrypted email.
Good: A web-based secure message system (hopefully in PHP) that I could host and run over SSL. I haven't been able to find anything like this.
Maybe I'm asking the wrong thing or the wrong way. Any suggestions are appreciated!
