  1. Hello everybody! During a few last years I received multiple appeals to release AES library that I developed in 2011 into open-source. So, I've just done exactly this: https://github.com/IgorTitov/LabVIEW-Advanced-Encryption-Standard I released it under MIT license (which means that there are no restrictions whatsoever). No VI passwords, no uglification. LabVIEWishly Yours, Igor Titov.
  2. Does any one have an idea on how to password encrypt an Excel file (or csv) in LabVIEW or zip up the excel file/csv and add a password to it that way? I need to be able to add a simple encryption to confidential patient data files after they are created and be able open them to read later by the same program. I've tried using OpenG to add a password protection to a Zip file but when I try to add a string variable to the password connector it says password (none) so it makes me feel like I'm doing this wrong. I couldn't really find any similar documentation or tutorials on
  3. ShaunR's recent topic on Security reminded me of a situation we explored in the summer and need to revisit at some point. We were looking for a method to protect the communication with a cRIO. The situation is that we need to communicate between a cRIO and a host on an unsecured network (manufacturing environment.) We concluded that we needed some form of encryption as well as a standard login mechanism but identified that having a single symmetrical key would not provide enough protection (for various reasons and specific use cases.) Therefore, we looked into SSL and LabVIEW Web Servi
  4. Hi, One of my customer is creating systems with high added value. These systems relies on a both CompactRIOs and deported computer code. These systems will be deployed all around the world, and should be hardly protected against copy. Concerning the computer code, they decided to use a dongle system to decrypt the exe each time this one is launched. How to do something similar with the RTEXE on a compactRIO ? Is there a solution to encrypt an RTEXE ? Is it possible to remove VI's block diagrams in a RT EXE ? Is this solution sufficient to protect the code from reverse engineering ?
  5. From the album: ShaunR

    SQLite database statistical analysis with AES 256 CBC encryption. N.B. 1. Multiple encoding runs produce new database byte-map. - differential analysis resistant. 2. Statistically indistinguishable from random data. - statistical analysis resistant.
  6. From the album: ShaunR

    SQLite database statistical analysis with AES 128 ECB encryption. N.B. 1. Multiple encoding runs produce identical database byte-map - susceptible to differential analysis. 2. Information leakage and correlation especially for zero values - susceptible to statistical analysis..

    SQLite database statistical analysis without encryption
