  • iPhone SQLite Password Field Encryption

    - by Louis Russell
    Good Afternoon Guys and Girls, Hopefully this will be a quick and easy question. I am building an App that requires the user to input their login details for an online service that it links to. Multiple login details can be added and saved as the user may have several accounts that they would like to switch between. These details will be stored in an SQLite database and will contain their passwords. Now the questions are: 1: Should these passwords be encrypted in the database? My instinct would say yes but then I do not know how secure the device and system is and if this is necessary. 2: If they should be encrypted what should I use? I think encrypting the whole database file sounds a bit over-kill so should I just encrypt the password before saving it to the database? If this is case what could I use to achieve this? I have found reference to a "crypt(3)" but am having trouble finding much about it or how to implement it. I eagerly await your replies!

  • Run VISTA disk check without reboot

    - by Chau
    I want to perform a surface scan on my harddisks (S-ATA, P-ATA, USB and E-SATA) in windows VISTA. Is it possible to do this without scheduling the scan on next reboot? It takes a lot of time and I would like to be able to use the computer during the scan. I can accept that this might not be possible on the window partition disk, but I cannot see why it shouldn't be possible on other disks.

  • CPU/Mem/Disk utilization (average) after process has completed

    - by BassKozz
    Ubuntu Server 9.10 So there is the time command which will show you the time it took for a specific process/command to run after the command has completed. For example: :~$ time ls real 0m0.020s user 0m0.000s sys 0m0.000s I'd like to also collect the average CPU usage, Memory, and Disk (i/o) utilization after the process has completed using time (or another command if necessary). How can I accomplish this? Mainly I am using this to benchmark MySQL import performance using different innodb_buffer_pool_size settings.

  • Do I need to replace my hard disk?

    - by Sneha Kamath
    Hello everyone. Whenever I start my computer Ubuntu pops up the following error: A hard disk may be failing one or more hard disk report health problems A friend of mine ran some test and it was found that my hard disk has 74 bad sectors. Is this merely a software issue that will be solved after a complete format of my hard disk, or is it a hardware issue and I will have to replace my hard disk? Awaiting your responses. Thanks, Sneha Kamath.

  • FIPS-compliant encryption in .NET 2.0

    - by Odrade
    We have a .NET 2.0 application that uses the RijindaelManaged class to encrypt some sensitive data. This was fine until we ran into some machines that require the use of FIPS-compliant algorithms. We'd like to switch to AesCryptoServiceProvider, but most of our target machines haven't upgraded past .NET 2.0. Requiring an upgrade is out of the question. After all, upgrades are scary! Is there any way we could use AesCryptoServiceProvider in a .NET 2.0 application? Since 3.5 uses the 2.0 CLR, I was hoping there might be a way to build the needed libraries into the app. Failing that, could someone point me to a reference on the native API that's wrapped by AesCryptoServiceProvider?

  • AES Encryption library

    - by Spines
    Is there a library or something that will allow me to simply call a function that will AES encrypt a byte array? I don't want to deal with multiple update blocks/transformFinal/etc, because there is a possibility I will mess up...

  • Loading and storing encryption keys from a config source

    - by Hassan Syed
    I am writing an application which has an authenticity mechanism, using HMAC-sha1, plus a CBC-blowfish pass over the data for good measure. This requires 2 keys and one ivec. I have looked at Crypto++ but the documentation is very poor (for example the HMAC documentation). So I am going oldschool and use Openssl. Whats the best way to generate and load these keys using library functions and tools ? I don't require a secure-socket therefore a x.509 certificate probably does not make sense, unless, of-course, I am missing something. So, do I need to write my own config file, or is there any infrastructure in openssl for this ? If so, could you direct me to some documentation or examples for this.

  • Creating a Cerificate for Bouncy Castle Encryption

    - by Gordon
    I am trying to create a self-signed certificate to use for encrypting an email using bouncycaste. What would be the best way to generate a certificate? I have tried using openssl but I have had problems with certificate. Here is the code I am using to encrypt, I am using 3des. SMIMEEnvelopedGenerator gen = new SMIMEEnvelopedGenerator(); gen.addKeyTransRecipient(x509Cert); // adds an X509Certificate MimeBodyPart encData = gen.generate(mimeBodyPart, SMIMEEnvelopedGenerator.DES_EDE3_CBC, "BC");

  • Archiver Securing SQLite Data without using Encryption on iPhone

    - by Redrocks
    I'm developing an iphone app that uses Core Data with a SQLite data store and lots of images in the resource bundle. I want a "simple" way to obfuscate the file structure of the SQLite database and the image files to prevent the casual hacker/unscrupulous developer from gaining access to them. When the app is deployed, the database file and image files would be obfuscated. Upon launching the app it would read in and un-obfuscate the database file, write the un-obfuscated version to the users "tmp" directory for use by core data, and read/un-obfuscate image files as needed. I'd like to apply a simple algorithm to the files that would somehow scramble/manipulate the file data so that the sqlite database data isn't discernible when the db is opened in a text editor and so that neither is recognized by other applications (SQLite Manager, Photoshop, etc.) It seems, from the information I've read, that I could use NSFileManager, NSKeyedArchiver, and NSData to accomplish this but I'm not sure how to proceed. Been developing software for many years but I'm new to everything CocoaTouch, Mac and iPhone. Also never had to secure/encrypt my data so this is new. Any thoughts, suggestions, or links to solutions are appreciated.

  • Encryption messages in a queue between 2 dlls.

    - by scope-creep
    Hi, I'm sending messages between 1 dll and another, effectively posting messages onto the dll input queue and receiving a messages back from the dll output queue. These two dlls are very tightly integrated. DLL 1 is a producer,and DLL2 is the consumer. I want to encrypt the messages before they are sent. What would be the best approach? Any help would be appreciated.

  • Stop windows 7 disk trashing when idle

    - by Konrads
    Hello, I installed Windows 7 on VMWare and it works just fine! However, when I leave the machine idling and work on my host OS, Windows 7 decides that it is a good idea to trash disk and kill performance. How do I disable these background processes? is it just indexer?

  • encryption of a single character

    - by SystemicPlural
    What is the minimum number of bits needed to represent a single character of encrypted text. eg, if I wanted to encrypt the letter 'a', how many bits would I require. (assume there are many singly encrypted characters using the same key.) Am I right in thinking that it would be the size of the key. eg 256 bits?

  • two AES implementations generated different encryption results

    - by YCL
    I have an application that uses an opensource "libgcrypt" to encrypt/decrypt a data block (32 bytes). Now I am going to use Microsoft CryptAPI to replace it. My problem is that the libgcrypt and cryptApi approaches generate different ciphertext contents as I use the same AES-256 algoritjm in CFB mode, same key, and same IV, although the ciphertext can be decrypted by their own correspndingly. Could some tell me what is the problem? Thanks.

  • .NET Compact Framework Connection String encryption/securing

    - by Crazydog
    I'm writing an application in C# for a smart device running Windows Mobile 6.1. It's pretty basic. Just querying a database and getting results. Nothing too fancy. This program is only going to be deployed internally, but we still want to be secure with our SQL connection info. What's the best way I should go about encrypting/securing my connection string in the program? I've seen examples for .NET programs using AppSettings, but I'm not seeing a Setting stab in my Solution properties. This is my first time developing an application in C#/Visual Studio 2008, so there might be some kind of setting I'm missing. Thanks for the help.

  • iPhone - AES256 Encryption Using Built In Library

    - by Robert
    Hey all, I am using http://pastie.org/966473 as a reference as all I need to do is encrypt something using AES256 encrypting. I created a class and put the implementation in the pastie on top of the implementation for my class. @implementation //pastie code @end @implementation //my class code @end In my class code I create a NSMutableData and try to call the EncryptAES method and I get a warning saying it might not respond to that. What am I doing wrong here? do I need to implement the pastie code elsewhere? Thanks for any help.
