![]() ![]() a cracking effort against salted Site A works only against Site A. Further, because the values are unique to that site, this work can't be shared with other hackers to make their lives easier. They can't just look up the passwords online, they have to deploy massive CPU resources to check trillions of possible passwords against the encrypted store, looking for matches. Using a salt (adding a unique value, local to the site) means that global hash tables won't work, and attackers have to do a LOT more work to crack the hashed passwords. If a site is breached, and uses the base hash function without salt, then all their hashes can be almost instantly checked against the precomputed tables, and the attackers will have plaintext versions of all the 'easy' passwords within a few minutes. They can generate hashes for basically every possible input password up to a certain length. If everyone uses just the base function itself (SHA-1 in this case), then once someone has figured out what "password" or "secret" hash to, they can store that in a database, and share it on the Internet. A site can't get the password from the hash, but if you type in the same password again, it will hash to the same value as what's in their system, so they know it's you. A hashing function takes an arbitrary input, and does a series of mathematical transformations on it, resulting in a bitstream that's (ideally) unique for every input, not predictable, and not reversible. Unsalted passwords? Rainbow tables? I feel like fuckin Andy Rooney here.Ī hopefully brief explanation: salting is the process of adding an extra value to a password before giving it to the hashing function. Posted by whatzit at 10:37 AM on JĬlockzero: I had to read this a few times to convince myself I wasn't having a stroke. Some information is gained by aggregating little nuggets, but even more is by reading what is written directly on an employee's profile. People in this field use LinkedIn as a key tool to identify what their competitors are doing, what the org chart looks like, and what new technologies they seem to have in the pipeline. This is something that can benefit many of you, regardless of your industry or actual position. In addition, my current position is working in competitive and technical intelligence. ![]() By happening to notice that a close friend/colleague was connected with a hiring manager, I could humbly request that a good word be put in for me. Another time, it kept me from finding myself unemployed after ending up in a position that was not ideal for me at the time. Once, it was a key element to the networking operations that landed me a job in France. This is a screenshot of both versions running side by side in Ubuntu Mate 16.Has anyone ever gotten any good leads from Linkedin? This should work at least for Ubuntu 16.04 (Xenial) to 17.10 (Artful). (You may need to edit the old keepassx launcher to point to /usr/bin/keepassx to run version 2). ![]() Now, you can create a new launcher icon to /usr/local/bin/keepassx to run the 0.4 version. This will put the binary executable in /usr/local/bin/keepassx. Install the executable ( sudo make install).Run make to build the executable ( make).Run qmake to create the Makefile ( qmake PREFIX=/usr/local).Edit the file src/lib/random.cpp to add the line #include around line 22 (this is a requiremente to compile with the version of GCC in latest Ubuntu versions).Get into the directory ( cd keepassx-0.4.4/).Decompress it ( tar xvf keepassx-0.4.4.tar.gz).Download the source code of the last 0.4 version (0.4.4) keepassx-0.4.4.tar.gz.Install the build dependencies ( sudo apt-get install build-essential libqt4-dev libxtst-dev qt4-make).For those of you who prefer to compile old or missing packages or who want to have both KeepassX version 2 and 0.4, you may follow this instructions: ![]()
