Fortify 2.2.6
Fortify offers an easy-to-use, simple-to-install program that provides world-wide, unconditional, full strength 128-bit cryptography to users of Netscape Navigator (v3 and v4) and Communicator (v4). more>>
Fortify 2.2.6 offers an easy-to-use, simple-to-install program that provides world-wide, unconditional, full strength 128-bit cryptography to users of Netscape Navigator (v3 and v4) and Communicator (v4). If you routinely use Netscape's export-grade web browsers, (i.e. the ones you can download from the Internet), then you need Fortify.

GnuPG 1.4.7
GnuPG - Install GnuPG without having to compile it more>>
GnuPG is a command line tool and is licensed under the GNU GPL.
After downloading the archive, please verify its validity with MD5 or the detached sig. If not, the file may have been tampered with and may not be secure.
Once you have GnuPG installed, visit the Mac GPG Website for GUI tools to avoid having to use the command line.
MD5 (GnuPG1.4.5.dmg) = b164ca16abffaceeb4d4198cc4bec8df
MulleCipher Framework 1.1
MulleCipher Framework - Wraps some public domain cryptography more>>
The digest algortihms have been tested on Mac OS X and passed the tests. So I assume, that they work as expected. The crypto routines encrypt and decrypt correctly. I have not checked that the output is compatible with their respective implementations on Intel machinery, though I assume that it is.
Enhancements:
- Added prebinding, the prebind address is -seg1addr 0x32000000. You can easily change this by changing the link options.
- By default crc32 is not compiled in anymore, because there is already a crc32 routine in libz. If you define BUILD_CRC32 its back in.
- Created project files for the new Project Builder, so you dont have to import the projects yourself.
Freenet 0.5.2
Freenet is a large-scale peer-to-peer network which pools the power of member computers around the world to create a massive virtual information store open to anyone to freely publish or view more>>
Freenet 0.5.2 won't make you disappointed cause it pools the power of member computers around the world to create a massive virtual information store open to anyone to freely publish or view information of all kinds.
Major Features:
- Highly survivable: All internal processes are completely anonymized and decentralized across the global network, making it virtually impossible for an attacker to destroy information or take control of the system.
- Private: Freenet makes it extremely difficult for anyone to spy on the information that you are viewing, publishing, or storing.
- Secure: Information stored in Freenet is protected by strong cryptography against malicious tampering or counterfeiting.
- Efficient: Freenet dynamically replicates and relocates information in response to demand to provide efficient service and minimal bandwidth usage regardless of load. Significantly, Freenet generally requires log(n) time to retrieve a piece of information in a network of size
- Freenet is free software which lets you anonymously share files, browse and publish "freesites" (web sites accessible only through Freenet) and chat on forums, without fear of censorship.
- Freenet is decentralised to make it less vulnerable to attack, and if used in "darknet" mode, where users only connect to their friends, is very difficult to detect.
- Communications by Freenet nodes are encrypted and are routed through other nodes to make it extremely difficult to determine who is requesting the information and what its content is.
- Users contribute to the network by giving bandwidth and a portion of their hard drive (called the "data store") for storing files. Files are automatically kept or deleted depending on how popular they are, with the least popular being discarded to make way for newer or more popular content. Files are encrypted, so generally the user cannot easily discover what is in his datastore, and hopefully can't be held accountable for it. Chat forums, websites, and search functionality, are all built on top of this distributed data store.
- An important recent development, which very few other networks have, is the "darknet": By only connecting to people they trust, users can greatly reduce their vulnerability, and yet still connect to a global network through their friends' friends' friends and so on. This enables people to use Freenet even in places where Freenet may be illegal, makes it very difficult for governments to block it, and does not rely on tunneling to the "free world". .
Enhancements:
- Unspecified improvements
- Bug fixes.
OpenSSL 0.9.8k
Open Source toolkit implementing the Secure Sockets Layer and Transport Layer Security protocols more>> Open Source toolkit implementing the Secure Sockets Layer and Transport Layer Security protocols
OpenSSL 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) protocols as well as a full-strength general purpose cryptography library.
The OpenSSL project is managed and maintained by a worldwide community of volunteers that use the Internet to plan, communicate, and develop the OpenSSL toolkit and its related documentation.
OpenSSL is based on the excellent SSLeay library developed from Eric A. Young and Tim J. Hudson.
NOTE: The OpenSSL toolkit is licensed under an Apache-style licence, which basically means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions.
Enhancements
- Dont set val to NULL when freeing up structures, it is freed up by underlying code. If sizeof(void *) > sizeof(long) this can result in zeroing past the valid field. (CVE-2009-0789) [Paolo Ganci ]
- Fix bug where return value of CMS_SignerInfo_verify_content() was not checked correctly. This would allow some invalid signed attributes to appear to verify correctly. (CVE-2009-0591) [Ivan Nestlerode ]
- Reject UniversalString and BMPString types with invalid lengths. This prevents a crash in ASN1_STRING_print_ex() which assumes the strings have a legal length. (CVE-2009-0590) [Steve Henson]
- Set S/MIME signing as the default purpose rather than setting it unconditionally. This allows applications to override it at the store level. [Steve Henson]
- Permit restricted recursion of ASN1 strings. This is needed in practice to handle some structures. [Steve Henson]
- Improve efficiency of mem_gets: dont search whole buffer each time for a
- [Jeremy Shapiro ]
- New -hex option for openssl rand. [Matthieu Herrb]
- Print out UTF8String and NumericString when parsing ASN1. [Steve Henson]
- Support NumericString type for name components. [Steve Henson]
- Allow CC in the environment to override the automatically chosen compiler. Note that nothing is done to ensure flags work with the chosen compiler. [Ben Laurie]
