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.
The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, fully featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) as well as a full-strength general-purpose cryptography library.
jSaluki is a small, easy to use Java hyperelliptic curve cryptography library. A simple hyperelliptic crypto system is implemented in the example file.
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).
Linux FreeS/WAN is an implementation of IPSEC & IKE for Linux. IPSEC is Internet Protocol SECurity. It uses strong cryptography to provide both authentication and encryption services. Authentication ensures that packets are from the right sender and have not been altered in transit. Encryption prevents unauthorised reading of packet contents.
Graphical certification authority
Graphical certification authority is an interface for managing RSA keys and certificates, and the creation and signing of PKCS#10 requests. It uses the OpenSSL library and a Berkeley DB for key and certificate storage. It supports importing and exporting keys and PEM DER PKCS8 certificates, signing and revoking of PEM DER PKCS12, and the selection of x509v3 extensions. A tree view of certificates is presented.
Generic Security Service
A bug that prevented 3DES gss_wrap from working in the Kerberos 5 mechanism was fixed. The library headers file now works even when the Kerberos 5 mechanism is disabled. The package has been tested on more platforms.
GPGMail (v30) (10.3 (Panther))
GPGMail is a bundle for MailViewer.app (on MacOS X Server) and Mail.app (on MacOS X), providing a front-end to gpg for some operations. GPGMail extends Apple's MailViewer/Mail application and allows you to read and send PGP authenticated and/or encrypted messages. You can use PGP for plain and MIME messages, following RFC 2015 guidelines. Source code is available.
tinc is a Virtual Private Network (VPN) daemon that uses tunneling and encryption to create a secure private network between multiple hosts on the Internet. This tunneling allows VPN sites to share information with each other over the Internet without exposing any information.
Mixmaster is an anonymous remailer. Remailers provide protection against traffic analysis and allow sending email mail anonymously or pseudonymously. Mixmaster consists of both client and server installations.
