Encrypt and Decrypt files with gpg 4096 bits - ElmagoLoko - Feb 24, 2017

Generate a RSA Key:

Code 
gpg --gen-key

To encrypt a file

Code 
gpg -c file.to.encrypt

To decrypt a file

Code 
gpg file.to.encrypt.gpg

But gpg will not do entire directories. For entire directories you have several options, ecryptfs is popular.

# Install if ecryptfs-utils if needed]

Code 
sudo apt-get install ecryptfs-utils

Make an encrypted directory

Code 
ecryptfs-setup-private

That will make a directory "Private". Any data you put into the directory Private will automatically be encrypted when you log out and decrypted when you log in.

If you want a different behavior or a different directory ...

Code 
mkdir ~/secret

Code 
chmod 700 ~/secret

Code 
sudo mount -t ecryptfs ~your_user/secret ~your_user/secret

Put your data into ~/secrte

To encrypt

Code 
sudo umount ~your_user/secret

To Decrypt

Code 
sudo mount ./secret ./secret -o key=passphrase,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_passthrough=no,ecryptfs_enable_filename_crypto=yes
