Encrypting a file In LINUX

Sending and receiving files in a plane text is vulnerable to attacks. So we can eaisly encrypt a file using this method in linux

For Encryption–

#openssl enc -aes-256-cbc -e -in <plain_text_file> \out <encrypted_file_name>

For Decryption—

#openssl enc -aes-256-cbc -d -in <encrypted_file_name> \-out <plain_text_file>

File will ask for the password (passphrase) so that unauthorised acces to this file can be prevented.
