AES256 file encryption

encrypt file secret.txt with openssl

openssl aes-256-cbc -a -salt -pbkdf2 -in secrets.txt -out secrets.txt.enc

info: give your password double to protect encryption

decrypt file secret.txt.enc openssl

openssl aes-256-cbc -d -a -pbkdf2 -in secrets.txt.enc -out secrets.txt

info: you will be ask for your given protected given password

you can also encrypt tar.gz files, so if you have multiple files to encrypt than compress it with zip , bzip or tar.gz and than you can encrypt it
