Re: Does an encrypted file show the same number of bytes?

Yeah, that would prevent anyone who has the plaintext file from matching it with the length of the encrypted file. Just make sure those other files are truly random in size. If you used the same additional file in every instance and there were many files to inspect, a person with all this data might...

Re: Does an encrypted file show the same number of bytes?

While I agree that the file length information could be used to make assumptions about what files a person is transmitting if they already have the plaintext file, it's not a design flaw nor a loophole. The point of AES Crypt is to encrypt, not try to hide the fact a whistle-blower, for example, is ...

Re: Does an encrypted file show the same number of bytes?

That's an interesting question, not because I don't know the answer, but because I'm quite interested in knowing why you ask. Don't need to tell me. I can imagine a few scenarios. For example, a whistle-blower that wants to sneak out documents without those documents being potentially matched based ...

AES Crypt in JavaScript

Folks, Aaron Flin reached out to me saying he had written a version of AES Crypt in JavaScript. I've had a few people request things like that over the years, so I wanted to provide a link to his repository here. He said it might still have some bugs in the code, so I don't (yet) want to link to it ...

Re: New feature: Original filename in encrypted file

Understood. I've had that request before, but then others have expressed that they like the fact the name isn't preserved. In fact, there is some plaintext metadata in the .aes file header that folks asked to have added and others want it removed. The challenge is each of these competing options lea...

Re: New feature: Original filename in encrypted file

I don't understand the problem. AES Crypt doesn't care what the file is named. When you encrypted a file named "foo.jpg", the resulting AES Crypt file will be "foo.jpg.aes" by default. When you decrypt a file named "foo.jpg.aes", the resulting file will be "foo.jpg". The only error some people get i...

Re: Decrypt in memory?

I created a test file on my desktop with a bunch of lines of text in it. I called it "passwords.txt". I then encrypted it. I then went to the command prompt and typed the following command and received the corresponding output: C:\Program Files\AESCrypt>aescrypt.exe -d -p abc123 -o - c:\users\paulej...

Re: Decrypt in memory?

After the -o you need hyphen. Looks like you need a space before passwords.txt.aes. That means to send it to "standard out", which is your screen at the command line.

However, if the file is binary, it would look like that.

Re: Decrypt in memory?

Let's say it decrypts a file to memory. How do you plan to access it? And once the program exits, you won't have access to the memory, either.

This is really only useful to people integrating the code into other programs. It's not something useful otherwise.
