Security :: AES Example / Implementing AES - Key Not Valid For Algorithm forums.asp.net

I need an example on how to implement AES encryption/decryption in .NET. I've been googling but haven't yet found any good examples. I've for example found AES example whih after some research wasn't 100% AES. I have to make sure by AES encryption/decryption is 100% AES, as I have to send email to the authorities explaining how I use AES (with secret key all), so they can hire some encryption expert which verify that we encrypt/decrypt it correctly. So he can verify that the what I implemented in AES is actually 100%. I'm reading the AES standard and how it's to be implemted in .NET Here is some code I'm having trouble with: [Code]....

Which Symmetric Encryption Algorithm Is The Fastest For Smaller Messages stackoverflow.com

I am interested in help selecting one of the common symmetric encryption algorithms (Twofish, AES, etc) based on performance criteria (fastest encryption/decryption). We are currently leaning toward AES, but since the communications we are sending back and forth don't really need that level of encryption, a less secure algorithm would be acceptable for a performance gain. We will be using the selected algorithm to encrypt/decrypt messages (should be no longer than 200 characters) that are being sent between the client and server (Javascript client and PHP on the server) over HTTPS. The speed of the algorithm is important because the encryption/decryption process will need to keep up with messages as they arrive/depart via sockets on the server. I have found one site that has benchmarks for encryption and I plan to do my own testing, but I was hoping for input from SO on selecting an encryption for speed. note that the message will not be sent over HTTPS, they will be sent over HTTP.

Protecting Database Encryption Key phpbuilder.com

My question sounds simple but I haven't been able to find a good answer in various articles on security. I need to store Social Security numbers (and other sensitive data) in mySQL using PHP. I plan to encrypt them using some form of symmetric encryption, such as AES. The question is: how/where do I store the encryption key? If someone can get ahold of my database or otherwise compromise security, it seems like they would easily be able to get the key just by accessing it in the same way my PHP files access it. Am I missing something? Is there some location on the server combined with some PHP techniques whereby the key can be kept out of the hands of someone who is sophisticated enough and determined enough to grab the database records themselves? It seems completely pointless to encrypt data if the encryption key can be found.

Motorola Droid X :: Wifi On Droid X androidforums.com

I tried connecting it to my router through N. My router was basically on auto settings 11bgn mixed, auto channel width, and auto security. But this basically gives me no internet connection at all on my Droid X. The Droid X simply switches over to WiFi for internet, which it's getting no access to, which is making wifi essentially useless for me. I turn off WiFi, and voila, internet through 3G again. So I read up on the problem with AES encryption? This means I had to use TKIP encryption, but wireless N doesn't work with TKIP, meaning I have to use wireless G, essentially making my N speeds useless, although in reality my internet speeds aren't going over the max 54mbps G speeds offers, but I'd still like my router to be able to transmit N speeds to my computers. Anyway, even switching to wireless G and TKIP encryption, it works sometimes, but then intermittently it will stop working. I don't change anything, it just stops working. This doesn't happen with other laptops connected to my router, or other phones even as I had a Droid Incredible before.

I have a N80 for almost two years. I used to be able to detect and access the wifi connection at home through a Belkin N1 wireless router. Ever since the wireless router went faulty and I have it for an one-to-one exchange, my N80 is not able to detect the WLAN signal at all. There is no issue of detecting the Wifi signal on my N82 though. This is the setting I have on my router. Doea anyone able to shed some lights on what is wrong here? My N80? The router settings (which one?). FYI, i tried on another N80 and it is not detecting the signal too.

Wifi Disabled On Startup? www.sevenforums.com

4 days ago we changed the security settings on our home router/network from WPA2- Personal TKIP+AES to just AES. I then changed my Asus UL80vt-A1 wireless adapter settings (Atheros AR9285) to match (from TKIP to AES).This was the ONLY change I made to the system.Then the fun began. First off a new adapter appeared in my Network connections. It is Wireless Network Connection 2- Microsoft Virtual WiFi Miniport Adapter. Well, that was not there before I made the changes to the security settings. Googling results indicate it is a normal part of Windows 7, it really had never been there before.Restarting the computer the wireless adapter shows as disabled, and I have to run the network diagnostics to re-enable it. It does not matter if I do a shut down or hibernate (my preferred way of shutting down the laptop before going somewhere). So I thought I should change the security settings back to what I had (TKIP+AES) and set my notebook to TKIP. I also did a Windows Update just in case. I ran a scan with Avast Antivirus, Microsoft Security Essential and Malware Bytes to see if something evil had gotten in, all were clean.Now when I hibernate my laptop it takes 4-5 minutes to shutdown. When I restart it takes 4-5 minutes to restart. I am staring at the intro screen waiting for the logon to appear. Once I get logged in the wifi adapter appears connected, but the computer is acting like it is hung up until all the open programs have finished loading. I can't do anything until the 27 open tabs in Firefox have completely finished being restored. Takes another 3-4 minutes.

Applications :: Won't Find Screen Sharing Info / Between Two Computers forums.macrumors.com

I'm going to be using iChat for the first time and want to use the screen sharing feature between two computers running 10.6. iChat's documentation (http://docs.info.apple.com/article.h.../en/17157.html) says: "While every screen sharing connection uses encryption, the highest level of security requires both participants to have MobileMe subscriptions with encryption enabled. If this is the case, you will see a lock icon in the screen sharing window." I'm wondering: 1. What is the difference between the encryption that "every screen sharing connection uses" and the enhanced security allowed with MobileMe accounts? How does this compare with, say, doing VNC over an SSH connection? 2. I understand that one can get a free MobileMe account which only has iChat capabilities. Does this free MobileMe account enable iChat encryption, or do I have to pay $99/year to get that?

Applications :: Cascading Ciphers To Encrypt Files? forums.macrumors.com

My question is related to using cascading ciphers to encrypt files (specifically using Truecrypt.) I am considering using Serpent > Twofish > AES. I've heard a couple of different theories on this approach: 1. The resulting encryption will only be as strong as the weakest algorithm. 2. The resulting encryption will be as strong as the strongest algorithm. Which theory is right? Truecrypt uses the same passphrase for each cascading cipher. I've ben thinking that as soon as one cipher is cracked (probably the one which was used last in the encryption sequence) the plain text passphrase would be able to be simply used against the remaining two ciphers. Am I right? Finally, is Truecrypt encrypting the data with one cipher, then encrypting the resulting encrypted data with another cipher, and then another? Or are the three ciphers being used to encrypt different sections of data?

SQL Server Standard 2005, SQL Mobile 2005 Data Encryption Issues social.msdn.microsoft.com

Hi, I have a central database server that is runnning on SQL 2005 standard edition and Windows server 2003 standard as OS. I realise that I can use SQL statements to encrypt and decrypt the data inside the standard SQL. However, how do I read and write the data via an web application coded in C#.net and is also running on the same machine? Another issue is, I need to replicate some of the data in this SQL standard over to a SQL mobile running on a mobile device running on Windows CE 5.0. The mobile device also needs to read and write data to the encrypted data via a C#.net application. Question is, with all these requirements to be met, can I use AES?� I know that AES is not available on Windows XP and Windows Server 2000 and I cant find AES in the .net compact framework. how do i go about ensuring security? how do I ensure that the symmetric key is the same both on the SQL standard and SQL mobile? thank you.

VS 2008 - How To Implement New Encryption Algorithms www.vbforums.com

I want to try and use the new encryption algorithms provided with .NET 3.5. Any links or examples for how to use one of them to encrypt xml content? As written on msdn site is: The following algorithms are included: Advanced Encryption Standard (AES) with key sizes of 128 and 256 bits for encryption. Secure Hash Algorithm (SHA-256 and SHA-384) for hashing. Elliptic Curve Digital Signature Algorithm (ECDSA) using curves of 256-bit and 384-bit prime moduli for signing. This algorithm is provided by the ECDsaCng class. It allows you to sign with a private key and verify with a public key.

IPhone :: Wifi Won't Connect To Comcast? discussions.apple.com

I have Comcast Xfinity internet using an Arris TG862 wireless gateway. The default security settings for the modem is WPA/WPA2-PSK(TKIP/AES) with automatic channel selection. Whenever I try to connect to the wireless with these settings my phone responds with "Unable to join network" I saw on another iphone forum that to connect with the Iphone the router should bet to security mode WPA2-AES with channel 1,6, or 11. Whenever I do any of these setting the phone says it connects and shows the wifi logo instead of 3g. However, whenever I try to open a web page I get the server not responding error. I checked the router setup page and it shows that no other device is connected besides by hardwired desktop computer. I have checked the wifi on my laptop (which I am currently on) to check if it's a general wifi issue or just my phone. Info: iPhone 4, iOS 5.1.1, Arris TG862 Wireless Gateway

Motorola Droid X :: Unable To Connect With Wifi androidforums.com

I've tried different settings in my router (wpa/wpa2 just wpa, just wpa2, tkip, aes) I refuse to go below wpa encryption. My current settings WPA2 AES. I'm running a Linksys WRT400N dual-band router latest firmware, 2.4ghz mode set to mixed b,g,n.

Phone probably knew I was on here complaining about it but any help you can give me to obtain a wifi connection better without having to spend 15mins each time trying to get it to connect would be great.

Fedora Networking :: Can't Connect To Wireless Gateway forums.fedoraforum.org

I've just installed fedora 10 on my Dell Inspiron 1525, and I can't connect to my wireless net. I know how to manually enter the SSID (and have no clue what a BSSID is), MAC address, and I know it's infastructure (well, it's not ad-hoc, so it must be). The problem is, my router uses a 64-bit encryption protocol, and there's no '64-bit' key option under Wireless Security's dropdown. Is there any way around this, aside from either changing the encryption protocol, or plugging it in manually (neither of which are options)?

Hardware :: Using DD-WRT To Bridge AEBS (Or Vice-Versa) forums.macrumors.com

I want to setup my linksys WRT610N (running DD-WRT) in my office, and connect it to my AEBS which will sit in my living room, connected to my gateway.

I'm just having trouble on defining the security settings. I'm using WPA2 Personal on my AEBS. What encryption algorithm does the AEBS use? My wrt gives me options for aes, tkip, or both.

Automatic Website Login, Long URLs, Encryption? stackoverflow.com

We currently have two applications that will be using this. One is a web application, the other a desktop app. Both of these require users to login/authenticate, the same credentials can be used for either application.I want to build an automatic login mechanism that will fill in all the various login/order details and be able to call this from either app mentioned above. I've been thinking that the best way to do this is to pass this information encrypted through the URL. ie https://mysite.com/TakePayment.aspx?id=GT2jkjh3.... Since we don't want to integrate the payment processing too tightly into the desktop app to reduce our PCI scope, we decided to have it open the browser to a central, secured payment page through a simple shell execute with the full URL causing the default browser to open that page.Originally we were using AES for the encryption, but this is currently being re-examined as we would prefer not having to give out the key to the end user (AES is symmetric, symmetric encryption = both parties need the private key, why bother even encrypting then since we're going to be distributing the app?) So I'm looking at switching it over to use Public Key Encryption with the built in RSA routines within .NET After coding up the RSA portion I noticed most examples on the net used 1024bits for the key-length, I went with this and now have our portal working with public key encryption, however the URLs generated are much much longer than when I was using AES so it made me start researching what the max limits for URLs are. http://www.boutell.com/newfaq/misc/urllength.html Says that IE is the limiting browser at about 2048 characters in the path portion. My initial tests with the RSA encryption show my urls will be around 1400 chars long.My questions boil down to this:1) Is there a better way for passing information from a desktop app to a website that I'm not thinking of? I'd prefer it be just as easy to use from another web page as it is from the desktop, hence my current solution.2) Is 1024 bit RSA keys necessary? Or overkill for something like this? A shorter key would mean shorter encrypted text right?3) Are there any other unforeseen problems with URLs in the 1200-1400 character range? Proxies? Firewalls? Web-Accelerators?

General :: No Support For Encryption Of External SD Card forum.xda-developers.com

If you enable device encryption on devices with external sd card, the external sd card always remains unencrypted. As you cannot really control for every app where to store its data, you have some of your app-data on internal sd (encrypted) and some of you app-data on external sd (encrypted). To me this seems to be a security hole, concerning device encryption. why cm team does not include encryption for external sd cards, like some oems do? They put so much effort in security features and on the other side they leave parts of the local storage encrypted?

AES Written In PHP? bytes.com

Is anyone aware of any already-written code I can use that implements AES-192 in PHP? BACKGROUND: I don't have mcrypt compiled into my PHP, and I have an application where I need to encrypt and decrypt 128 bits (1 block only) using AES-192. My plan is to implement AES in PHP (directly, as PHP code). I did a speed test with PHP, and a loop with 10,000 iterations, with each iteration containing several bitwise manipulations and random number generations, required 0.11 seconds to complete on my server. I'm sure that one block of AES is less CPU cycles than that, so the upper limit on the server time to do one block should be 0.11 seconds of server time.
