The distributable NWC file exporter lets project teams using Navisworks software generate whole-project models for simulation and analysis. Team members can generate optimized NWC files directly from design applications without needing a licensed seat for Navisworks. The NWC exporter works with a range of products, including AutoCAD and Revit software, as well as 3ds Max, Bentley MicroStation, and Graphisoft ArchiCAD software. The NWC file format supports transfer of both object geometry and associated metadata.

The Autodesk DWG TrueView app is a free stand-alone DWG viewer. It is built on the same platform as AutoCAD, an industry-standard, paid-for computer-aided design (CAD) and drafting software application. DWG TrueView allows you to view the latest DWG, DWF, and DXF file formats, just as you would in AutoCAD, but without paying a license fee.
After extracting the files, move onto the actual install (once you've accepted the Autodesk license and services agreement). The install took about five minutes. Installation instructions in this version are only in English, although other language versions are available. Once the install is complete you can hit finish - the program will not automatically open.
DWG is a file extension used for drawing programs, such as computer-aided design (CAD) software. DWG TrueView is aimed primarily at professionals who take input from AutoCAD DWG or DXF drawings but don't need to edit or prepare the drawings. Architects, engineers, and construction professionals are likely to find it a useful program.
Buying individual licenses for full-featured CAD software can quickly become prohibitively expensive. Autodesk DWG Trueview provides a useful solution for those who only need to view, convert, and export DWG files and don't require design functionality.
If your OrCAD Capture CIS designers work in a multi-user networked environment, you can leverage CIS functionality for easier management of your group's part and footprint libraries and files you can browse. Placing libraries and files in a designated location forces all engineers to pull information from a central source. This not only promotes data integrity, since all users are getting part information from a common source, but also eases the burden of administrating libraries.
Simplified DES (SDES) was designed for educational purposes only, to help students learn about modern cryptanalytic techniques.SDES has similar structure and properties to DES, but has been simplified to make it much easier to perform encryption and decryption by hand with pencil and paper.Some people feel that learning SDES gives insight into DES and other block ciphers, and insight into various cryptanalytic attacks against them.[51][52][53][54][55][56][57][58][59]
A block cipher is so-called because the scheme encrypts one fixed-size block of data at a time. In a block cipher, a given plaintext block will always encrypt to the same ciphertext when using the same key (i.e., it is deterministic) whereas the same plaintext will encrypt to different ciphertext in a stream cipher. The most common construct for block encryption algorithms is the Feistel cipher, named for cryptographer Horst Feistel (IBM). As shown in Figure 3, a Feistel cipher combines elements of substitution, permutation (transposition), and key expansion; these features create a large amount of "confusion and diffusion" (per Claude Shannon) in the cipher. One advantage of the Feistel design is that the encryption and decryption stages are similar, sometimes identical, requiring only a reversal of the key operation, thus dramatically reducing the size of the code or circuitry necessary to implement the cipher in software or hardware, respectively. One of Feistel's early papers describing this operation is "Cryptography and Computer Privacy" (Scientific American, May 1973, 228(5), 15-23).
Threefish: A large block cipher, supporting 256-, 512-, and 1024-bit blocks and a key size that matches the block size; by design, the block/key size can grow in increments of 128 bits. Threefish only uses XOR operations, addition, and rotations of 64-bit words; the design philosophy is that an algorithm employing many computationally simple rounds is more secure than one employing highly complex — albeit fewer — rounds. The specification for Threefish is part of the Skein Hash Function Family documentation.
Elliptic Curve Cryptography (ECC): A PKC algorithm based upon elliptic curves. ECC can offer levels of security with small keys comparable to RSA and other PKC methods. It was designed for devices with limited compute power and/or memory, such as smartcards and PDAs. More detail about ECC can be found below in Section 5.8. Other references include the Elliptic Curve Cryptography page and the Online ECC Tutorial page, both from Certicom. See also RFC 6090 for a review of fundamental ECC algorithms and The Elliptic Curve Digital Signature Algorithm (ECDSA) for details about the use of ECC for digital signatures.
Hash functions, also called message digests and one-way encryption, are algorithms that, in essence, use no key (Figure 1C). Instead, a fixed-length hash value is computed based upon the plaintext that makes it impossible for either the contents or length of the plaintext to be recovered. Hash algorithms are typically used to provide a digital fingerprint of a file's contents, often used to ensure that the file has not been altered by an intruder or virus. Hash functions are also commonly employed by many operating systems to encrypt passwords. Hash functions, then, provide a mechanism to ensure the integrity of a file.
Note that these sites search databases and/or use rainbow tables to find a suitable string that produces the hash in question but one can't definitively guarantee what string originally produced the hash. This is an important distinction. Suppose that you want to crack someone's password, where the hash of the password is stored on the server. Indeed, all you then need is a string that produces the correct hash and you're in! However, you cannot prove that you have discovered the user's password, only a "duplicate key."
In early 1999, Shamir (of RSA fame) described a new machine that could increase factorization speed by 2-3 orders of magnitude. Although no detailed plans were provided nor is one known to have been built, the concepts of TWINKLE (The Weizmann Institute Key Locating Engine) could result in a specialized piece of hardware that would cost about $5000 and have the processing power of 100-1000 PCs. There still appear to be many engineering details that have to be worked out before such a machine could be built. Furthermore, the hardware improves the sieve step only; the matrix operation is not optimized at all by this design and the complexity of this step grows rapidly with key length, both in terms of processing time and memory requirements. Nevertheless, this plan conceptually puts 512-bit keys within reach of being factored. Although most PKC schemes allow keys that are 1024 bits and longer, Shamir claims that 512-bit RSA keys "protect 95% of today's E-commerce on the Internet." (See Bruce Schneier's Crypto-Gram (May 15, 1999) for more information.)
Without meaning to editorialize too much in this tutorial, a bit of historical context might be helpful. In the mid-1990s, the U.S. Department of Commerce still classified cryptography as a munition and limited the export of any products that contained crypto. For that reason, browsers in the 1995 era, such as Internet Explorer and Netscape, had a domestic version with 128-bit encryption (downloadable only in the U.S.) and an export version with 40-bit encryption. Many cryptographers felt that the export limitations should be lifted because they only applied to U.S. products and seemed to have been put into place by policy makers who believed that only the U.S. knew how to build strong crypto algorithms, ignoring the work ongoing in Australia, Canada, Israel, South Africa, the U.K., and other locations in the 1990s. Those restrictions were lifted by 1996 or 1997, but there is still a prevailing attitude, apparently, that U.S. crypto algorithms are the only strong ones around; consider Bruce Schneier's blog in June 2016 titled "CIA Director John Brennan Pretends Foreign Cryptography Doesn't Exist." Cryptography is a decidedly international game today; note the many countries mentioned above as having developed various algorithms, not the least of which is the fact that NIST's Advanced Encryption Standard employs an algorithm submitted by cryptographers from Belgium. For more evidence, see Schneier's Worldwide Encryption Products Survey (February 2016).
The second DES Challenge II lasted less than 3 days. On July 17, 1998, the Electronic Frontier Foundation (EFF) announced the construction of hardware that could brute-force a DES key in an average of 4.5 days. Called Deep Crack, the device could check 90 billion keys per second and cost only about $220,000 including design (it was erroneously and widely reported that subsequent devices could be built for as little as $50,000). Since the design is scalable, this suggests that an organization could build a DES cracker that could break 56-bit keys in an average of a day for as little as $1,000,000. Information about the hardware design and all software can be obtained from the EFF. 2ff7e9595c
