DMitry (Deepmagic Information Gathering Tool) is a UNIX/Linux command line
program coded purely in C with the ability to gather as much information as
possible about a host.
Hashcat is an advanced CPU-based password recovery utility for FreeBSD,
Windows 7/8/10, Apple OS X, and GNU/Linux, supporting seven unique modes
of attack for over 100 optimized hashing algorithms.
JSON Object Signing and Encryption (JOSE) for Erlang.
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.
hitch is a network proxy that terminates TLS/SSL connections and forwards
the unencrypted traffic to some backend. It's designed to handle 10s of
thousands of connections efficiently on multicore machines.
hlfl stands for "High Level Firewall Language". It permits writing
firewalling rules using a high level language, and transforms them into
rules for real software, like ipfilter, ipchains or cisco rules.
You could make contact with the developers by subscribing to
<hlfl@hlfl.org>. There is also an announce ML at <hlfl-announce@hlfl.org>.
These lists are managed by majordomo (write to <majordomo@hlfl.org> with
"help" in the body of your mail).
HoneyBadger is primarily a comprehensive TCP stream analysis tool for
detecting and recording TCP injection attacks. HoneyBadger will also
include a variety of prototype TCP stream injections attacks which
prove that the TCP attack detection is reliable.
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.
HotSSH is an interface to Secure Shell, for GNOME and OpenSSH. It
intends to be a better experience than simply invoking "ssh" from an
existing terminal window.
* Fast search-based interface for new connections
* Also display and search of local (Avahi) SSH servers
* Tabbed display with automatic session saving (Firefox style)
* Status bar with information like latency to server and output of
remote uptime
* Close integration with OpenSSH features like connection sharing
(near-instant new tabs)
* NetworkManager integration to easily reconnect after a network
change, great for laptops
Hpenc is a fast encryption command line tool with the following features:
* Authenticated encryption - your data cannot be forged or corrupted without
detection.
* Parallel processing - hpenc uses block IO and you can process multiple blocks
simultaneously, which is extremely useful if you have multi-core environment.
* Strong ciphers - hpenc uses the state-of-art aes-gcm and chacha20 ciphers
* Easy interface
* Hardware acceleration - hpenc can utilize all its
advanced cryptography functions defined for AES-NI and PCLMULQDQ instructions
(that must be supported by openssl). For those with old or embedded CPU (such
as ARM), hpenc provides portable and fast chacha20 cipher.
* Simple key management
* Secure random numbers generator - hpenc can work as pseudo-random numbers
generator. In a set of standard tests (diehard) on the generated sequences
hpenc generates secure sequences of pseudo-random numbers on a very high
speed (gigabytes per second).
