Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Hi, i have the same problem.
We have a laptop that stucks in the boot screen of windows and we get a blue screen (probably after an update) and we need to decrypt the drive from veracrypt or at least get the data.

Steps we have done:

1) We imaged the drive in order to not touch the original installation. We did a sector by sector image.

2) Then we have mounted the image in Windows 10 as an external drive.

3) We installed Veracrypt 1.22 Beta (i tried also the stable version but it doesn't work either)

4) The drive is recognized and identified as RAW in the system

5) We open Veracrypt and try to decrypt it. We put the correct password and we also select the Identify partion without pre-boot Authentification: http://prntscr.com/isenbx

6) The password is recognized and we get in this screen: http://prntscr.com/isemdv

7) Unfortunately we cannot see the dat a inside the drive

8) Using a data recovery tool we can understand that the partition is still encrypted.

I have uploaded a video in youtube that explains the problem and you can see step by step the process we use to recover the data. Youtube Video here: https://youtu.be/pWBgzZQqRSU

as i told you we have no Veracrypt Recovery Disk but we have the password which is working correctly.
a) How we can recover the data from this partition / disk ?
b) What is the best way to image the whole disk to another disk unencrypted so we can fix also the Windows 10 boot problems ?

I need to read any type of file
encode it using huffman
decode it using huffman
MD5  Sum should match after decoding

only condition is the encoded file should have less size than original file
can anyone help me with that it can be done in java or C++
Hi team,

I recently created a plain gmail account. I tried to send 500 in one time from my personal iMac and it went through.
Although, my colleage tried to sen 200 emails in one time but unfortunately didn't go through.
There is a message says "....don't support encryption."
I suppose it means that this account is not using TSL.

Is there a way to fix this issue, so I can have the ability to send so many emails without this warning?

Thanks you,
I need to be able to encrypt PDF documents in VFP programatically and then create a zip file with the encrypted PDF to email

Please assist.

Hello, I have just recently taken over IT Support for a couple of small education schools. GPDR is kicking in very soon and I just wonder how this affects the I.T. in terms of encryption i.e. Office 365 emails or emails in general, USB sticks, logging into PCs, ipads, antivirus, backups etc, etc

Does the GPDR state that EVERYTHING has to be encrypted i.e. PC\laptop hard drives or just confidential data onsite and data that is going offsite, do all USB sticks need to be encrypted ? Data on the server does this need to be encrypted i.e. word and excel files, what is the rule regarding these areas please ? It's a minefield.

Any help would be most grateful,

Thanks guys.

I imagine encrypting server drives would slow down RAID. But what happens if a drive fails and needs to be replaced?
Will the encryption allow hard drive replacement?

I'm disabling USB ports for my team in order to tighten things up and help improve/prevent DLP, and meet some requirements that are being externally driven by our customers

Just curious what the preferred method is of instructing them how to work without flash drives going forward. IE emailing things to themselves

Or what happens if you're at a conference and there's an issue with accessing your email or the corporate network, and you need access to the particular file but cannot because the USB ports are now disabled and you couldn't bring a backup copy

Was doing some research online and couldn't find anything. Thoughts?
We are using gmail with our own Domain name.

How do we encrypt Outlook 2007, 2010, 2013, 2016 emails so the recipient has to enter a password to open email (w/ or w/o attachments)?

Also, can we do the same within Gmail emails itself via web browser?

In this article, I explain what Convergent Encryption is and how it can be used.

Hello all,

just a question on Bitlocker for the experts. I've tried to find an answer online to no avail.

I know in Windows 10 pro (and previous o/s) you can have different login methods after encryption. You can encrypt the hardrive by right clicking C: and selecting the "Turn Bitlocker on" method, following the standard/ recommended process. However, i also know that in gpedit.msc you can configure the "Require additional authentication at startup" so that you can enter a PIN/Password on boot.

My question is.. What is the difference between them both? If i choose *not* to have an additional authentication at startup but have the hardrive encrypted, what are the security implications here?

I would really appreciate help/guidance if possible :)
I received a warning of RDP as following,

The following certificates were part of the certificate chain sent by
the remote host, but contain hashes that are considered to be weak.
|-Subject             : CN=PBVA01
|-Signature Algorithm : SHA-1 With RSA Encryption

I want to confirm the signature algorithm used by RDP, so where can I check the certificate and the signature algorithm of RDP? Thanks.
Hello all,

When i reinstall my Windows 10, I delete the partition on my second hard drive by error.
That second hard drive was encrypted with BitLocker.
Is there a software to retrieve the data that was on that drive.
I have the decryption key.

My O.S. is Windows 10.  OneDrive sync client version

We have an external hard drive which was BitLocker encrypted by a Windows 10 PC.

This external hard drive is used to back up data on our PCs and servers.

Each month, we would back up  this data.

Each time the external hard drive is plugged into a PC, a password is required.

BitLocker does is not supported by our Windows Server 2003 servers so the password would not be unlocked.

Decryption is the first step we would do and then backup data from all PCs and servers.

This time, while the external hard drive was in the decrypting process and over 80% complete, the PC was accidently turned off.

After this happened, when trying to login with password to this drive to continue the decryption process, the password is not accepted.

I tried to unlock the drive by using the correct recovery key and it is also not accepted.

The last thing I tried was unlocking the drive through command line with administrative privilages with recovery key and the message back was; "The password failed to unlock volume E:".

I have researched this an some people have imaged the hard drive.

There is a lot of important data on this external hard drive and we would like to know how to unlock the drive and access the data rather than imaging the drive if possible as we would just have an external hard drive which is unusable.

All help appreciated.

We have a user that password-protect a lots of his documents.  He uses WinRar v3.61 (and latest WinRar) , WinZip v9 (and the latest) also uses the latest 7z,  In a meeting a colleague mention that the problem with these apps, though all uses AES-256 (except the old version of WinRar),  when unzipping the files, all the apps create an unprotected version of the contents on another area of the computer.  What is the exact location of these folders?
We would like to know if we can create keyfiles of an existing volume in order to use the keyfiles to open the volume if the user forgets the password.  Some time back an EE commented on keyfiles with similar topic bit haven't been able to find it.   Can this be done? (trying to safeguard access to the volume if the users forget)
