Collaborate Disseminate
I have encrypted a file using a program with a password and would like to decrypt it on another device just with the password. Is there any software that takes the password, runs it through all key derivation functions and decrypts the fil… Continue reading Decrypting a file knowing only the password
I know nothing about cryptography. How does one encrypt a file in the strongest possible way, such that it can be accessed some years later?
I prefer that it should be fairly resistant from brute force and other possible ways attacks.
I ne… Continue reading Strongest file encryption available
Assuming the hacker has access to the ciphers of each of the versions, will it help him/her to decipher the original file(s) by doing some sort of comparison of the ciphers?
I’ve been trying to figure this out using an encrypted zip file as an example.
I am quite familiar with the idea that PBKDF2 creates a key drivered form a password and then that key is used to encrypt the file using AES. But how does JtR … Continue reading How does JtR crack password protected documents?
I have a laptop with Ubuntu 20.04 operating system. I am logged into my Chrome browser using my Google account. This means, every time I open my browser, I am already logged into all the Google services (Gmail + Chrome browser with all pas… Continue reading If someone steals my unencrypted, password protected laptop, would they be able to get into my Google account?
I have recently received an e-mail from an existing support group e-mail box with the following characteristics:
written in the language used in company’s HQ (different from English which is the primary communication language)
had a zip … Continue reading How to quickly find out what the threat nature of a password protected archive without getting infected?
I’ve been working on just a fun side project in C++ to practice encryption algorithms and I sort of ran into a bit of a roadblock of sorts. To summarize the project I have a text file of encrypted passwords and sites the passwords are for,… Continue reading Password Vault Storing Passwords
Most of the stuff on my laptop is benign; and the hassle of full disk encryption is not worth it. On the other hand, one or two folders I would love to encrypt and password protect.
What’s the best way to do this? I see a couple of optio… Continue reading Folder level encryption on a Windows 10 Pro laptop
I’m working on a university project where I have to encrypt a drive using a digital certificate. I have found software that can do this for files/folders, but not for entire drives/partitions. Is there any software like this? If no, what’s… Continue reading Software that let’s you encrypt a drive using a certificate
There are a couple of files / tools which provide file-level encryption. I guess PDF and ZIP are probably the most commonly known ones.
I wonder what scenario they actually help with or if it just is a bad solution.
For example, if I wan… Continue reading What is the attack scenario against which encrypted files provide protection?
