openssl, is this a decent level of encryption?

[mertnlee]

Hi Folks,
I am encrypting for storage in the cloud using the following openssl command. Is this secure or can I do better with different openssl arguments?

#!/bin/bash
#
read -p Password: password
cat $1 | openssl enc -iter 1000 -bf -salt -out $1.dat -pass pass:"$password"

Cheers,
Marty

That all depends on what you mean by "cloud." Are you uploading to S3 or another service?

By cloud I mean uploading to google drive or carrying about with me on a losable usb stick. The encryption is to protect my backups.

You can use rclone for syncing to Google Drive, but the setup process seems pretty involved if you want encryption.

You could always encrypt the USB stick with LUKS or the like rather than try to do file level encryption. VeraCrypt might be more user friendly though.
