gnome-keyring-sharp is a fully managed implementation of libgnome-keyring.
When the gnome-keyring-daemon is running, you can use this to retrieve/store
confidential information such as passwords, notes or network services user
information.
Apache XML Security for C++
The Apache XML Security for C++ library is an implementation of the XML
Digital Signature and Encryption specifications, along with some
additional XKMS code.
GnuPG Made Easy (GPGME) is a C library designed to make access to GnuPG
easier for applications. It provides a High-Level Crypto API for encryption,
decryption, signing, signature verification and key management. Currently it
uses GnuPG as its backend.
GPuTTY is a frontend to the SSH client, using the Gtk+ toolkit.
GNU SASL is an implementation of the Simple Authentication and Security Layer
framework and a few common SASL mechanisms. SASL is used by network servers
(e.g., IMAP, SMTP) to request authentication from clients, and in clients to
authenticate against servers.
GNU SASL contains a library (`libgsasl'), a command line utility (`gsasl') to
access the library from the shell, and a manual. The library includes support
for the SASL framework (with authentication functions and application data
privacy and integrity functions) and at least partial support for the CRAM-MD5,
EXTERNAL, GSSAPI, ANONYMOUS, PLAIN, SECURID, DIGEST-MD5, LOGIN, NTLM and
KERBEROS_V5 mechanisms.
The library is portable because it does not do network communication by itself,
but rather leaves it up to the calling application. The library is flexible
with regards to the authorization infrastructure used, as it utilizes callbacks
into the application to decide whether an user is authorized or not.
GSS is an implementation of the Generic Security Service Application Program
Interface (GSS-API). GSS-API is used by network servers (e.g., IMAP, SMTP) to
provide security services, e.g., authenticate clients against servers.
GSS consists of a library and a manual.
fsh -- Fast remote command execution
The problem: logging in to a remote system with a cryptographic
solution such as lsh or ssh takes time, due to the computationally
expensive key exchanges that occur when the connection is
established. It is common to trigger a lot of remote logins while
using remote CVS, which makes it painfully slow compared to having the
repository locally.
The solution: reuse the secure tunnel once it has been
established. fsh is a drop-in rsh-compatible replacement for ssh that
automatically reuses ssh tunnels.
Honggfuzz is a general-purpose fuzzing tool. Given a starting corpus of test
files, Hongfuzz supplies and modifies input to a test program and utilize the
ptrace() API/POSIX signal interface to detect and log crashes.
Fcrackzip is a fast and featureful ZIP password cracker, written in
portable C (and optional x86 assembly). It allows the user to recover
forgotten ZIP archive passwords, using either a brute force or
dictionary attack on the provided files.
A command line idea encryption and decryption utility written by
Dr. Richard De Moliner.
IDEA (International Data Encryption Algorithm) is a block cipher devel-
oped by Dr. Xuejia Lai and Prof. Dr. J. L. Massey at the Swiss Federal
Institute of Technology.
