Tiger Envelopes makes encryption automatic with
almost any email program, allowing you to continue
reading and writing mail the way you always have.
It installs with one click on Windows, Mac, and
Linux. It automatically configures Outlook,
Outlook Express, Thunderbird, Mac Mail, and KMail. Tiger is a personal mail proxy server with automatic
encryption. It uses POP3, IMAP, and SMTP to work with
almost any mail client, crypto plugins to work
with almost any type of cryptography, and Java to
run on almost any operating system. Plugins for
Bouncy Castle, GPG, and PGP are included.

The NIO Framework sits on top of the Java NIO
library and hides most of the complexity of plain
NIO and SSLEngine. With it, one can easily
implement secure, high-performance Java network
applications.

rfrandpass is a PHP application that generates random
passwords according to your specifications (minimum length,
number of alpha/numeric/symbol characters, etc). It
features many output crypt and hashing options. Also
included is a native PHP library for performing NT and LM
hashing.

The tcb suite implements the alternative password
shadowing scheme on Openwall GNU/*/Linux (Owl)
which allows many core system utilities (passwd(1)
being the primary example) to operate with little
privilege. It is being made available separately
from Owl primarily for use by other distributions.
This package contains three core components of the
tcb suite: pam_tcb (a PAM module which supersedes
pam_unix), libnss_tcb (the accompanying NSS
module), and libtcb (a library for accessing tcb
shadow files, used by the PAM and NSS modules as
well as by user management tools on Owl).

YAPET is a small text based password manager. It
features the Blowfish encryption algorithm and
runs on most modern Unixes.

Linux VPN Masquerade allows you to use an IPSec or PPTP VPN host (client or server) behind a Linux masquerading firewall. No more hogging the cable modem when you need to connect to the office network.

The Enhanced File Crypt/eXtended File Stealth System (EFC/XFSS) makes
your uploaded files safe on the server so that no one can read them
without knowing a few details to decipher the files. It generates
different obfuscated names and encrypted files so no one will know what
the original format or name was.

Figaro's Password Manager 2 (FPM2) is a GTK2 port
of Figaro's Password Manager, originally developed
by John Conneely. It allows you to securely store
your passwords, which are encrypted with the
AES-256 algorithm. It allows you to copy
passwords or usernames to the clipboard or primary
selection. If a password is for a Web site, FPM
can keep track of the URLs of your login screens
and can automatically launch your browser. You can
also teach FPM to launch other applications. FPM
can sort your passwords into categories. Finally,
it has a password generator that can help you
choose good passwords.

Nettle is a cryptographic library that is designed to fit easily in more or less any context: in crypto toolkits for object-oriented languages (C++, Python, Pike, etc.), in applications like LSH or GNUPG, or even in kernel space. In most contexts, you need more than the basic cryptographic algorithms; you also need some way to keep track of available algorithms and their properties and variants. You often have some algorithm selection process, often dictated by a protocol you want to implement. And as the requirements of applications differ in subtle and not so subtle ways, an API that fits one application well can be a pain to use in a different context, which is why there are so many different cryptographic libraries around. Nettle tries to avoid this problem by doing one thing, the low-level crypto stuff, and providing a simple but general interface to it. In particular, Nettle doesn't do algorithm selection. It doesn't do memory allocation. It doesn't do any I/O. The idea is that one can build several application- and context-specific interfaces on top of Nettle and share the code, testcases, benchmarks, documentation, etc.

Email sends email to remote SMTP servers via the
command line, which makes it useful in cron jobs.
It will send to any RFC standard remote ESMTP
server, is TLS/SSL enabled, and will allow you to
encrypt, sign, and design your message on the fly.
It has the capability to use signature files with
dynamic options, address book functionality, and
users can also attach pictures, binary files,
documents, or whatever they want. It is completely
compatible with GNUPG for encryption and signing,
and is easy to configure and use.

RC-Crypt can be used to encrypt or decrypt data
using the RC5 algorithm. It operates on 128-bit
data blocks, adding random characters for padding
if necessary. The key size can be chosen by the user, but 64 bits or greater is recommended. It has many
input/output options, making this a versatile piece
of software suitable for embedding into scripts.

gnoMint is a tool for easily creating and managing
certification authorities. It provides fancy
visualization of all the pieces of information
that pertain to a CA, such as x509 certificates,
CSRs, and CRLs. gnoMint is currently capable of
managing a CA that emits certificates that are
able to authenticate people or machines in VPNs
(IPSec or other protocols), secure HTTP
communications with SSL/TLS, authenticate and
cipher HTTP communications through Web-client
certificates, and sign or crypt email messages.

M2Crypto is built from Python, OpenSSL, and SWIG. It makes accessible to the Python programmer DH, DSA, RSA, symmetric ciphers, message digests, HMACs, and SSL and S/MIME functionality.
