minisip is a SIP VoIP soft phone that implements additional security features such as mutual authentication, encryption and integrity of on-going calls, and encryption of the signaling (SIP over TLS). These security features use work-in-progress IETF standards (SRTP and MIKEY).
suPHP is a combination of an Apache module (mod_suphp) and an executable which provides a wrapper for PHP. With both together, it is possible to execute PHP scripts with the permissions of their owner without having to place a PHP binary in each user's cgi-bin directory. suPHP doesn't need Apache's suExec, and provides a logging function.
The stunnel program is designed to work as an SSL encryption wrapper between remote client and local (inetd-startable) or remote server. It can be used to add SSL functionality to commonly used inetd daemons like POP2, POP3, and IMAP servers without any changes in the programs' code. It will negotiate an SSL connection using the OpenSSL or SSLeay libraries. It calls the underlying crypto libraries, so stunnel supports whatever cryptographic algorithms you compiled into your crypto package.
lsh is an implementation of the SSH protocol version 2. It is under active development. Developer contributions are welcome from both inside and outside the US.
MUTE File Sharing
MUTE File Sharing is an anonymous, decentralized search-and-download file sharing system. Several people have described MUTE as the "third generation file sharing network" (From Napster to Gnutella to MUTE, with each generation getting less centralized and more anonymous). MUTE uses algorithms inspired by ant behavior to route all messages, include file transfers, through a mesh network of neighbor connections.
JSch is a pure Java implementation of SSH2. It allows you to connect to an sshd server and use port forwarding, X11 forwarding, file transfer, etc. You can integrate its functionality into your own Java programs.
Secure FTP Bean
The Secure FTP Bean allows FTP connections to be made over SSL, including both implicit and explicit SSL connections, and passive and active data transfers with or without encryption.
Dropbear SSH Server
Dropbear is an SSH 2 server that is designed to be small enough to be used in low-memory embedded environments, while still being functional and secure enough for general use.
hsftp is an ftp emulator that provides the look-and-feel of an ftp session, but uses ssh to transport commands and data. hsftp executes UNIX commands on the remote host, and thus will fail on non-Unix remote hosts. If hsftp is not set SUID root, and you have supplied a password/passphrase, it might get paged out to your swap partition during prolonged inactivity. For security, hsftp can be compiled to drop SUID root privileges irrevocably on startup, immediately after locking the memory for the password. For RSA authentication, you can avoid to have hsftp caching the passphrase if you use ssh-agent. In this case, you can use hsftp securely without setting it SUID root. hsftp has been developed on Linux. It is known to compile on a variety of other UNIX flavours (at least FreeBSD, Solaris, AIX, and HP-UX), but may not work on all. Fixes for portability are welcome for inclusion.
SILC (Secure Internet Live Conferencing)(client)
SILC Client package is intended for end users who are looking for a good and full featured SILC client. The SILC Client package currently includes Irssi-SILC client that supports all SILC features, themes and much more. It is curses based but has a possibility of adding various other frontends to it. The Irssi-SILC client's user interface is based on the Irssi client (see Irssi project).
