secure the files with zip or rar?

I'd like to secure some files with zip or rar with password.
If I set the password to something very random that is not possible to guess like
srjte2SEfgs2

Does it mean it's very unlikely to break the archive?

 

That's a really weak password: http://www.itworld.com/article/2832...ds-would-it-take-to-break-your-password-.html

Also, the "security" of a compressed, password-protected file/folder is a false security: http://security.stackexchange.com/questions/35818/are-password-protected-zip-files-secure

You'd be better off using TrueCrypt/VeraCrypt.
