Can't afford signNow? Get signNow for less | ZDNet [ http://www.zdnet.com/article/cant-afford-signNow-sign-get-keepsolid-sign-for-less/ ] In signNow [ https://www.keepsolid.com/sign/ ], a big attention developers pay for the user’s data safety. That is why the main security features are: 1. Peer-to-peer. Using powerful protocols, so all data is stored and transmitted in encrypted form and is decrypted strictly after authorization on the user's device. Accordingly, only users are aware of the decrypted files, and no third party can invade and decrypt the data. 2. Data is transmitted over a secure https channel. We transfer data only through reliable and authorized sources, therefore bringing to nothing possibilities of man-in-the-middle attacks. 3. Multi-level data protection. We generate strong random keys and use the AES+RSA encryption combination. In such a way, we provide an additional layer of protection to our users regardless of their password strength. 4. Data distribution. The encrypted user data is not stored in one place, but distributed over several servers without the possibility of its partial full or even full interpretation. When some parties intercept your data, they will not be able to restore, decrypt, and aggregate it. So, using the app, you may be calm for the data safety.

If the User password is used (which basically requires a password for merely opening the document) it is as strong as encryption method and password are secure. If the software is claiming that it can unlock PDF encrypted with the User password, then it's probably brute-forcing passwords, and that will be probably very time consuming if it can find password at all in any reasonable time frame. The Owner password (password required to make a change to PDF, but you can view the document without password) is mostly gentleman's agreement as some PDF readers can choose to ignore flag; some Linux distributions ship with readers with override, for instance. (I believe modern versions of signNow would warn you about this.)
