I'm trying to decrypt using Rijndael in PHP, but appear to be getting different values compared to what i get when doing it using C#?

Here's my C# code:

    RijndaelManaged rijndaelManaged = new RijndaelManaged();
    rijndaelManaged.KeySize = 256;
    rijndaelManaged.BlockSize = 128;
    rijndaelManaged.Mode = CipherMode.CBC;

    ICryptoTransform decryptor = rijndaelManaged.CreateDecryptor(rgbKey, Array4);

    count2 = fileStream.Read(buffer4, 0, count1); //6D-18-80-01-DD-B6-3E-5B-26-83-CE-30-C7-AC-57-79
    cryptoStream.Write(buffer4, 0, count2);

    ^^ this value is 31-3B-3B-31-3B-3B-40-FD-00-20-A9-A2-00-08-71-CA

Open in new window


And here's my PHP code

    $rgbKey = "de299ceff91f2a216969a22e482a6c1616c6e64e552d46ffafb713f1743e32d1";
    $rgbIv = "ECCD26BE791BB360E2010F6378CD5631";

    $rijndael = new Rijndael();
    $rijndael->setKey($rgbKey);
    $rijndael->setIV($rgbIv);
    $rijndael->enableContinuousBuffer();
    $rijndael->setKeyLength(256);
    $rijndael->setBlockLength(128);

    echo bin2hex($rijndael->decrypt("6D188001DDB63E5B2683CE30C7AC5779")); 

    ^^ this value is c3d0ea2da27565c46fc7f1d2c0684baaf246

I have a large file containing many sub-folders & files (*.gpg) that are encrypted using gpg. I would like to decrypt them in place and remove the .gpg extension. All have the same passcode. My question is: can I decrypt all files in a folder, at the folder level by using a wildcard (*.gpg), or must I do each file in the folder individually?

my GnuPG command line looks something like this:
gpg  --batch --passphrase-fd 0 --decrypt *.gpg < pass.txt

if possible, a little help with the syntax would be appreciated

I'm doing an Android App that sends post request to my server which the target file is php file. Normal data is sent correctly but the problem starts when sending symbols like œ,Õ,€,ã. These are just replaced by ? so now I can't correctly interpret the data because it is not in a correct form. Here is my Android code I'm using
InputStream ByPostMethod(String ServerURL){
        InputStream DataInputStream = null;
        try{
            // Post parameters
            

            // Preparing

            URL url = new URL(ServerURL);

            HttpURLConnection cc = (HttpURLConnection)
                    url.openConnection();
            // Set timeout for reading InputStream
            cc.setReadTimeout(5000);
            // Set timeout for connection
            cc.setConnectTimeout(5000);
            // Set timeout to POST
            cc.setRequestMethod("POST");
            // Set it to true as we are connecting for input
            cc.setDoInput(true);

            // Opens the connection link
            cc.connect();

            // Write data (bytes) to the data output stream
            DataOutputStream dos = new DataOutputStream(cc.getOutputStream());

            dos.writeBytes(PostParam);
            // Flushes data outpu stream.
            dos.flush();
            dos.close();

            // Getting HTTP response code
            int response = cc.getResponseCode();

            // if Response code is 200/Ok then read InputStream

bitlocker encrypted drive on usb: we have a laptop with ssd drive with bitlocker encryption that crashed and won't reboot to windows.  Before reinstalling Windows 10, I'd like to know how to put the drive on external usb on another computer to try to retrieve data from it.  It just says it's not accessible and doesn't have an option to put in the encryption key.

Cloud Class® Course: Amazon Web Services - Basic

Are you thinking about creating an Amazon Web Services account for your business? Not sure where to start? In this course you’ll get an overview of the history of AWS and take a tour of their user interface.

I am having and issue with Citrix Receiver on one of the system I manage. I get the error message "This version of Citrix Receiver does not support the selected encryption. Please contact your administrator."  I found several topics suggesting corrupted registry entries and to use the clean-up utility.  I have done all that. I finally resorted to re-imaging the system and starting from scratch. This worked for about and hour until the user restarted the machine.  I have several other systems with the exact same setup that don't have this issue.  Where is this coming from? Has anyone resolved this issue?

Hi, I was looking for instructions on how to decrypt a drive that was crypted using veracrypt.  Like if I put the encrypted hard drive in another computer and wanted to decrypt it.

I tried dooing that today and got lost.  Also do I just need the password they use to log on the Veracrypt screen, or do I need to entire encryption key.

Thanks all.

Hi, I use rdx encryption software to encrypt the data on my RDX tape.  I put the password in and have it auto unlock the tape when it's inserted.  It works great and I love it, but one flaw, every time the server reboots, it looses the key and it won't auto unlock.  I have to open the software and enter the key again.  This is bad because I use it at many sites and am rarely at each location.

Question: is there a fix for this, or a work around?

Thanks a ton guys.

Currently our accounting staff has to manually download a file from our bank on a daily or weekly basis.  One of our system programmers wants to automate the process so Accounting does not have waste 1 hour/week on the download.   We have talked to the bank and all I get from them is that we need to open Port 22, setup a SFTP site and PGP for encryption.   The bank did send me some information on setting up PGP.  I have read some articles dealing with Linux  but for us this will be on a Windows 2012R2 server.  My question: Should I do this?  I would rather not due to the security but I will need facts to back me up.  Everything I have read is from 2010 or earlier.  I would like to get your opinions as toward If it is safe to proceed or not.  Also, if you say yes, if you have any thoughts on setup.

Thanks for your help

Hello,

I have been using a Netscreen SSG-5 firewall for my home office since 2009. For the first 5-6 years or so I logged into it fairly regularly to check on status, tweak configuration, and update the ScreenOS.  I have not logged into it for the past 2-3 years. I recently received an email from Lifelock warning me about VPNFilter malware that is targeting routers. This made me think about checking the status of my SSG5 to make sure it has the latest firmware and ScreenOS and to possibly change the password.  The problem is when I try to connect to the firewall at https://192.168.X.XX/ using Firefox I get an error message that the Secure Connection Failed with this specific error message:

Cannot communicate securely with peer: no common encryption algorithm(s). Error code: SSL_ERROR_NO_CYPHER_OVERLAP

I then tried using Chrome and received a similar error message:

This site can’t provide a secure connection 192.168.X.XX uses an unsupported protocol. ERR_SSL_VERSION_OR_CIPHER_MISMATCH

Internet Explorer also failed.

It has been a few years since I have worked with the firewall and I am a bit rusty in terms of the technology.  I did some searching and learned that the latest versions of Firefox, Chrome and IE won't accept weak "ciphers" and that my SSL and/or TLS are outdated.  I found something about RC4 not being safe.  I also think my certificate has expired.  It has been a few years and this is is a bit Greek to me.  All I know …

A friends IT dept want to encrypt his Lapotp

What’s the difference between beofre and after

Are there any keys that need to be kept after the event or is it like changing from FAT to NTFS  ? It just happens and it’s not noticeable to the end user?

Does this give the IT company more control of his laptop to remotely view it etc ?

Need to find Info on whether a particular email was read by the recipient in 365 Message Encryption (OME).

We use 365 message encryption to allow users to encrypt emails out to external users. The external user will receive an attachment that they open and then they need to either login (with the recipient email address) or use a one time passcode (sent by Microsoft) to allow them to read the message online. Because the attachment contains the link to read it online, there is no read receipt in 365 for this type of message delivery. We see in Message Trace that the message was delivered (the message notifying the recipient of an encrypted email), however we do not know if they opened the attachment and read the secure email. I would think Microsoft has a way to view this information, however I have been unable to get any results from support.

Is there a way in 365 to find out if the encrypted message was read?

For security reasons, if a message was sent securely to the wrong email, we need to know if it was read or not.

*Extra credit: Is 365 ever going to come out with read receipts on there encrypted emails like other providers??

Thanks in advance to anyone who might know more about this... it seems to be a black hole.

Do I need to create cert request on IIS but not with renew option?
https://weblog.west-wind.com/posts/2014/May/08/IIS-SSL-Certificate-Renewal-Pain


Do I need to mark old cert and than create cert request

or do I need mark IIS server and than create cert request option?

https://www.youtube.com/watch?v=ji0-HgB4wek
So,to sumarize.Create cert request on one server,import cert and  then export(pfx) and move it and import to another IIS server?
When I create cert request does this information(organizational unit,organization…)must match with old cert and if so how can I find those information on old cert?IT engineer who has purchase cert last year doesnt work here anymore.

I have Win10 Pro ver1709 laptops and we are slowly applying Bitlocker to our laptops. My team has just started noticing Bitlocker would begin encrypting on their own (we do not have MBAM) if left in the OU with the GPO settings applied in the attached doc. It did not do this previously, everything I read online states auto-encryption requires MBAM or manual initialization to begin encryption. We have seen this happen on more than one laptop. Also, something we just started doing was using SecureBoot which required us to use UEFI on the laptop.

- my GPO settings are in the attached file.

- if it is because of a GPO, which GPO setting (only I would have changed the GPOs, and I have not changed anything) is causing the auto-initialization? I prefer to have the settings needed WITHOUT auto-encrypting, unless that's not an option. please advise.
