Secluded Notes is a simple text editor that keeps each document as a part of its own executable. That part is called an "attachment", and the program encrypts/decrypts it on the fly with an AES 128-bit cipher. As long as you close the application, it automatically updates itself for the next run.
Cardpeek is a tool to read the contents of ISO7816 smartcards. It features a GUI to represent card data in a tree view, and it is extendable with a scripting language (LUA). The goal of this project is to allow smartcard owners to be better informed about what type of personal information is stored in these devices. The tool currently reads the contents of: EMV bank cards, Calypso public transport cards (such as Navigo, RavKav, and Mobib), Belgian eID cards, GSM SIM cards, the French Vitale 2 health card, some Mifare cards, and Moneo electronic purse cards.
libre is a generic library for real-time communications with asynchronous I/O support. It is written in portable POSIX source code that conforms to the ANSI C89 and ISO C99 standards. It is robust and fast, with a low memory footprint. It also features RFC compliance and support for IPv4 and IPv6. Protocol implementations include SIP, SDP, RTP/RTCP, BFCP, DNS, and STUN/TURN/ICE.
SSLsplit is a tool that performs man-in-the-middle attacks against SSL/TLS encrypted network connections for network forensics and penetration testing. It terminates SSL/TLS and initiates a new connection to the original destination, logging all data transmitted. It supports plain TCP and SSL, HTTP and HTTPS, and IPv4 and IPv6. For SSL and HTTPS, it generates and signs forged X509v3 certificates on-the-fly using the original certificate's subject DN and subjectAltName extension. It supports Server Name Indication, RSA, DSA, and ECDSA keys, and DHE and ECDHE cipher suites. It can also use existing certificates if the private key is available.
Wisecracker is a high performance distributed cryptanalysis framework that leverages GPUs and multiple CPUs. It allows security researchers to write their own cryptanalysis tools that can distribute brute-force cryptanalysis work across multiple systems with multiple multi-core processors and GPUs. Security researchers can also use the sample tools provided out-of-the-box. The differentiating aspect of Wisecracker is that it uses OpenCL and MPI together to distribute the work across multiple systems, each having multiple CPUs and/or GPUs.
crackxls2003 breaks the encryption on Microsoft Excel and Word 97/2000/XP/2002/2003 files which have been encrypted using the RC4 method. These files are encrypted using a 40-bit-long key. It will not work on files encrypted using versions later than 2007 or versions 95 or earlier, or if a non-default encryption method was used.
