Linux : HowTo Encrypt And Decrypt Files With A Password using GPG.
To encrypt and decrypt files with a password, use gpg command. It is an encryption and signing tool for Linux/UNIX like operating systems.
GnuPG stands for GNU Privacy Guard and is GNU’s tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures.
Please note that if you ever forgot your password (passphrase), you cannot recover the data as it use very strong encryption.

At @1:38
At the bottom of the video screen, it reads:
"Passphrase: Enter your secret password key"

Note that gpg is generally used to encrypt files for someone else -- that is, someone that you have their public key.
They, then, decrypt the file using their secret key.

I am mention this so that someone that is new to gpg will not accidentally use their secret key when performing symmetric file encryption.

In other words, if you are simply encrypting a file, for the purpose of allowing anyone to decrypt it, as long as they know the passphrase, then in this situation, they should not use the password for their secret key. They should make up a different, unrelated password.

When I type gpg exe.txt, my file opens without a password. Why doesn't it request a password?

Hi Amine, thanks for the short tutorial! Do you know which encryption algorithm is used with 'gpg -c filename'?

I read GPG is public key algorithm required public key and private key, then how it is using only one key that private key agorithm?

Do you have to have GPG? Or can you just encrypt them with bare bones Linux?

How do you instruct gpg to use a different cipher (different than AES)?
How do you instruct gpg to use a different bit length?

Thank you.

This doesn't work on folders, only files.
