How do you encrypt files?

Hello

I am looking for a software to encrypt files on Devuan, preferably with a graphical interface.

Thanks

Re: How do you encrypt files?

i was going to suggest that someone find a way to add gpg to the menu on spacefm file manager, though it already exists:

Requirements: an already existing gpg/gpg2 environment with a default key.

Re: How do you encrypt files?

gpg is good. You could use steghide too, hides files inside of images http://steghide.sourceforge.net/ , google Steganography.

Another interesting program i have found recently is called tcplay https://github.com/bwalex/tc-play

For gpg I use a program called gpg-crypter for ease of access - https://sourceforge.net/projects/gpg-crypter/

sorry first two are not gui programs, gpg-crypter is but you need knowledge of gpg and terminal commands to have it work. A good tutorial is here: https://theprivacyguide.org/tutorials/gpg.html

Re: How do you encrypt files?

Sorry to spam the thread but i find these topics interesting.

Have a read of this in regards to steganography .

https://en.wikipedia.org/wiki/Kerckhoffs%27s_principle

Kerckhoffs's principle

In cryptography, Kerckhoffs's principle (also called Kerckhoffs's desideratum, assumption, axiom, doctrine or law) was stated by Netherlands born cryptographer Auguste Kerckhoffs in the 19th century: A cryptosystem should be secure even if everything about the system, except the key, is public knowledge.

I have never ventured into Tomb territory.  It might suit your purposes if you put a little effort into it and is an "in house" solution.

Re: How do you encrypt files?

HectorBRX,

I don't have a GUI solution, but I can recommend gpg (part of gnupg package), which is very easy to use for symmetric encryption (same passphrase for both encryption and decryption) if that's what you are looking for.

To encrypt a file:

gpg --yes --batch --passphrase="YourSecretPasswordHere" -c yourfile.abc

To decrypt:

gpg --yes --batch --passphrase="YourSecretPasswordHere" yourfile.abc.gpg

gpg's default cipher algorithm for symmetric encryption is AES-128 (which gpg calls simply "AES"), but you can specify a different cipher by using the --cipher-algo flag (to see available ciphers, run gpg --version).

Re: How do you encrypt files?

I did not want to create another topic for this question. I wonder whether it is necessary to hide passwords with asterisks. All password managers hide passwords by default and I do not understand the point of this functionality. Is it only useful in public places?

Password manager's databases are encrypted with a Master Key but aside from that, I cannot find another reason to use them. Then, I thought of the hidden password functionality...

Re: How do you encrypt files?

Hiding the password is only useful if someone might be watching the screen (it doesn't help if they are watching your fingers as you type a password in). But it's impossible for a password manager to know if someone might be watching the screen, so they always assume the worst.

Re: How do you encrypt files?

I can imagine a future google service that warns you if someone is standing behind you when you're about to enter a password.
