Dear Users,

Starting with stunnel-5.09b1 it is now possible to use stunnel without certificates. https://www.stunnel.org/downloads.html

Example server configuration is:

[PSK server] accept = <stunnel_port> connect = <dst_port> PSKsecrets = psk.txt

, where the psk.txt may contain the following lines:

test1:oaP4EishaeSaishei6rio6xeeph3az test2:yah5uS4aijooxilier8iaphuwah1Lo

Example client configuration:

[PSK client 1] client = yes accept = 127.0.0.1:<src_port> connect = <stunnel_ip>:<stunnel_port> PSKsecrets = psk1.txt PSKidentity = test1

The psk1.txt file only needs to contain:

test1:oaP4EishaeSaishei6rio6xeeph3az
