Why not send drawings by e-mail attachment? Why have an active link out there for people and web crawlers to connect to to farm info?
I havent used any services like this but would advise the setting password option if this must be used, but I would not go this route of using this service and I explain below why:
You can add one more layer of security by enabling the captcha option or by setting a password. This way only people who successfully pass the captcha test or enter the password can see the links, while all the bots being rejected.
Thing is that I dont quite get is that if you have a web server with this info at a url path, and your using this service to mask the actual path. I would think that you would need to use a hosting service that provides this type of masking otherwise your actual domain is still out there to be crawled and so your still exposed.
Example being say you have www . mybusiness . com
You use their service and they give you www. encryptedurl . com
Now your information is exposed in 2 locations at your domain as well as at the encryptedurl that is password protected but your domain where it originated from is not protected the same.
This site states:
What is URL Crypt?
URL Crypt is a free service that lets you encrypt your links. There are hundreds of bots and servers that crawl the web for URLs and access them, copy the content or try to find who created them. By using URL Crypt, you are now safe from these risks.
Our mission is to protect you and all the other users of your URLs.
How URL Crypt can help?
Internet is not a safe place. URL Crypt is meant to help you protect your links by encrypting them in a safe way.
You can add one more layer of security by enabling the captcha option or by setting a password. This way only people who successfully pass the captcha test or enter the password can see the links, while all the bots being rejected.
All I see is a drop box for an already existing URL which is an exposed URL that is still out there to be crawled and information gathered from and they just give a means to bounce off of them like a proxy to hide the origin of the URL under a dynamic URL mask.
Looking at this website, I wouldnt trust it with protecting drawings from being stolen etc. Your actual website and web server needs to have authentication and be patched for all security attack types to protect your data, and then a 1 time use password given to a trusted individual by phone or e-mail. This way it allows a single individual a one time use of access to these files and hopefully they themselves are not a crook or have a security issue at their end for the info to become stolen such as they download it to their laptop and the laptop has a data leak hack on it or laptop stolen and information now in the wrong hands if the laptop itself is not encrypted to prevent someone from spinning up the drive with Linux and accessing the files getting around the OS password of the laptop.
