You could be doing a better job of website security... If only there was a simple way to implement SSL with signed keys? PHP-CA is an easy to use and easy to administer Certificate Authority that runs in PHP.
This is a library for easy accessing chip cards /smart cards via a chipcard reader. It currently works under Linux, FreeBSD and Windows. It is tested with Towitoko and Kobil readers.
A client for the passcracking.com online database ob MD5 and SHA1 Hashes.
It allows to generate MD5 and SHA1-Hashes from passwords and querying the database to get the password for a given hash.
Libraries and tools written in .NET managed code (MS/mono) to interact with GRC's Perfect Paper Password system [https://www.grc.com/ppp.htm] Source moved to GitHub: http://github.com/ErebusBat/pppNET
Paessler: Easy to Use With Enterprise Power. Free Trial
A low-code dashboard makes monitoring intuitive for any admin, while scripting and custom sensors give experts full control.
You shouldn't have to choose between a monitoring tool that's easy to use and one that's powerful enough for a complex environment. PRTG's low-code interface lets any admin build dashboards, set alerts and monitor devices without scripting, while custom sensors and full API access are there when your team needs deeper control. One platform, no compromise. Download a free 30-day trial now.
A distributed and dynamically threaded password cracker. Completely cross-platform using Qt 4.3. Utilizes 1 server and N clients to distribute password cracking across N machines, each of which can utilize N CPUs.
OpenRCA is a highly flexible and modular Certificate management and Registration Authority based on J2EE technology. OpenRCA is designed to be a very flexible, extensible and low cost enterprise PKI solution.
A simple java library (1.5.* and higher versions) in order to crypt (or decrypt) a file using a password. The library accepts the following parameters: an input file, the operation to perform, and the user password.
KeyStone is an editor program for Java keystore files, licensed under the GPL. KeyStone may help make your life easier if you're working with symmetric cryptography in Java.
Can you recover when it matters most? Take this quick assessment to identify gaps and build greater recovery confidence.
Is your recovery strategy as strong as you think? Take this quick self-assessment to check your recovery readiness and gain tailored insights. In only 2 minutes, you'll learn where you fall on the recovery readiness scale.
This project can be used to manage plugins in JAVA applications the framework provides checking of electronic signatures as well as hooks for user interaction (for example when certs are found that are not issued from a trusted authority
FSFS is a secure distributed file system in user space built over FUSE and OpenSSL. It stores AND transfers data between clients and server in secure form, leaving most of the cryptography to the clients, thus relieving the server of the additional work.
How do you find anything in the mountain of data on your PC? How do you organise, maintain, archive and protect your files? How do you avoid surrendering to the Powers of Darkness? Checkpoint Commander, the vital tool for Information Management!
A graphical tool for generating RSA and ECDSA cryptographic key-pairs, creating Certificate Signing Requests (CSRs) from them, and combining the key-pair with an issued digital certificate to create a secure portable container (PKCS12, JKS, JCEKS, etc.).
Bork is a very small, cross-platform file encryption utility. It is written in Java and designed to be included along with the files it encrypts for long-term storage (eg on CD-R). Its minimal external dependencies make it fairly futureproof.
BarTex is a system designed to create inexpensive tickets for events. It uses a crypto system to verify tickets using barcodes; thus eliminating the cost of expensive, colorful tickets that cannot be photocopied/forged.
WASTE is a mesh-based workgroup tool that allows for encrypted, private communication between distant parties on the internet, independant of local network organization.
NOTE: Development has moved to github: http://www.github.com/jaymzh/check_x509
check_x509 is a generic script to check X509 entities for expiration periods. It can be run from nagios, nrpe, cron, on the command line, or in other scripts or programs.
Hash Cracker is an application developed in java swings that allows a user to crack MD2, MD5, SHA-1,SHA-256,SHA-384,SHA-512 hashes either using brute force or using wordlists of the user's choice based on the users choice.
HashserGUI is a GUI interface for Jacksum. It is intended to provide a graphical tool to create hashes for files within a directory, and check the hashes generated. It works with many hash functions, as md5, sha1, sha256, sha512, md4, crc, etc.
Powerful 512bit pseudo random encryption, optimized for the x86-64 architecture. Coded in x86-64 assembly language, this has the potential to be one of the most powerful and fastest file encryption engines to date.
An implementation of Shoup's "Practical Threshold Signature" in Java. This is an (n,k)-threshold signature system: at least k parties out of n must independently sign a piece of data to produce a valid group signature.
