You can 7-zip it with a password. That's pretty simple to do and use - you only need an archiving program that supports it and can send that file and share the password.
That's not secure at all. For instance Microsoft will brute force the password for all of your zips to check for malware. It takes all of a few minutes to brute force zip encryption
Note that I said 7-zip, not zip. Are you making that claim for 7-zip?
Do you have a source for the brute forcing? Because I'm interested. If it's actually being done I doubt it'd go beyond predefined common password lists or exploiting non-secure passwording.
