Using stunnel: stunnel -d 995 -r localhost:pop3 -p /usr/local/etc/stunnel.pem Change the last argument to the path your private key/cert PEM file. Only downside is your pop3 logs now show the logins from 127.0.0.1. Ken Jones writes: > Thanks. I'm reading the url now. > > I think I confuse

FreeBSD Cryptography 101 - WAS - RE: vchkpw lacking authentication security

2001-01-19 Thread Joe Modjeski
For the record on FreeBSD systems! The use of DES/MD5 is controlled entirely by the crypt libraries. Vpopmail doesn't control the use of DES/MD5 passwords. If you dig through the source you can see that it sends the entire crypted password as the crypt key. ie.. crypt( 'joeblow', 'hJPcq6ffTNHuI

Dear Inter7 Developer: I recently discovered the following security drawback in vpopmail with vchkpw authentication: No matter how long you set the password to when adding a new user, only the first 8 characters of the password are used. So for example, if I do: ./vadduser [EMAIL PROTECTE
