Step 6: After installation is complete to see the list of encryption methods, run the following command: gpg2 –version
The term AES in this list is AES128. You can choose another encryption algorithm as the default one by adding a line to configure the file that GnuPG uses at runtime. The configuration file, called gpg.conf, is located in a hidden folder called .gnupg in the Home directory.
Step 7: The next step now is to edit the configuration file in gedit, run the following command in the Terminal window: gedit – / .gnupg / gpg.conf
Step 8: When opened you type ciphe–algo AES256 then save it.
Step 9: Now we begin to encrypt Files and folders on Ubuntu, for example encrypted with files – / Documents / Taimienphi.vn / Taimienphi.vn.txt
>> Type the command gpg –symmetric –cipher-algo AES256 – / Documents / Taimienphi.vn / Taimienphi.vn.txt
Then enter the password twice to confirm the password for the encrypted file.
Step 10: After encrypting Files and folders on Ubuntu we can add the password for that encrypted file with the command gpg –symmetric – / Documents / Taimienphi.vn / Taimienphi.vn.txt
