Here’s an easy way to encrypt your file using OpenSSL. The general syntax is:

openssl enc (cipher) -e -in (input file) -out (output file)

so to encrypt a “plaintext.txt” file, using aes256, you only need to run this command:

openssl enc aes256 -e -in plaintext.txt -out encrypted.txt

Similarly, to decrypt the file, you can run the command:

openssl enc aes256 -d -in encrypted.txt -out decrypted.txt
