Jul 17, 2013 · Introduction A problem has arisen recently in a project implementation. The vendor supplied software cannot use LDAPS to query our LDAP servers over a secure connection. They only support the clea…
A robust solution is to use Stunnel in lieu of OpenSSL. You can switch from OpenSSL to Stunnel in two ways: Offload SSL to a hardware device. Stunnel is a software program created to allow secure client-server transfers.Its purpose is to provide encryption via SSL (secure socket layer) to inetd daemons such as POP2, POP3, and IMAP Dec 03, 2011 · www.stunnel.org Stunnel is an open-source multi-platform computer program , used to provide universal TLS/SSL tunneling service. Stunnel can be used to provide secure encrypted connections for clients or servers that do not speak TLS or SSL natively. [ 2 ] www.stunnel.org Stunnel 是一个 自由的 跨平台 软件，用于提供全局的 TLS/SSL 服务。 针对本身无法进行TLS或SSL通信的客户端及服务器，Stunnel可提供加密安全连接。 These instructions will guide the user in the setup of a secure DICOM-TLS connection between Butterfly Cloud and the DICOM end-points within a customer’s network, by using TLS termination software Stunnel (stunnel.org). Stunnel will be configured to receive the encrypted TLS data, decrypt it, and forward the plain DICOM to the DICOM end Stunnel è un software libero multi-piattaforma, usato per fornire un servizio TLS/SSL universale.. Stunnel può essere utilizzato per fornire connessioni sicure per client e server che non supportano nativamente TLS o SSL.
stunnel یک برنامه منبع باز چند سطحی است که برای ارائه یک سرویس تونل زنی TLS/SSL جهانی استفاده میشود.. میتوان از stunnel جهت ارائه اتصالات رمزگذاری شده ایمن برای کاربران یا سرورهایی که به صورت بومی از TLS یا SSL بهره نمیبرند
Nibbler tested www.stunnel.org and gave it an overall score of 7.0 out of 10. This website is rated highly for Technology but wasn't so good at Marketing. Listen port. The portnumber to listen on (where the stunnel client connects to). For our example we choose 31280 here.. Target hostname. The hostname or ip number of the service to connect to, for this example the internal ip address of the proxy server. Thanks to HBruijn for pointing me in the right direction. I ended up doing the following, extracted from my config: [mail2-smtp] protocol = smtp accept = 25 connect = localhost:26 [mail2-smtps] accept = 465 connect = localhost:26 [mail2-smtp-submission] protocol = smtp accept = 587 connect = localhost:26 [mail2-smtp-ssl-client] protocol = smtp accept = 26 client = yes connect =

Using Stunnel. Stunnel is a free SSL proxy server that provides SSL services to Windows programs. Stunnel is easy to install, very robust, and functions transparently with very little overhead. The stunnel program is designed to work as SSL encryption wrapper between remote clients and local (inetd-startable) or remote servers.The concept is that having non-SSL aware daemons running on your system you can easily set them up to communicate with clients over secure SSL channels. stunnel3 stunnel [-c | -T] [-D [facility.]level] [-O a|l|r:option=value[:value]] [-o file] [-C cipherlist] [-p pemfile] [-v level] [-A certfile] [-S sources] [-a I second this. sTunnel is quite useful to disguise an SSH/VPN connection as a normal HTTPS connection, which most ISP/firewall will not reject since it will disrupt almost all users way too much. sTunnel is open source under GPL, so could someone please make it portable?
