Unlock PDF Online

If adding a password to your PDF file is one of the best ways to secure its content, sometimes it is not the best solution. And in some cases, it won’t be possible to use passwords at all.
For instance, companies that need to archive electronic documents and comply with various regulations will not use passwords. The ISO standard for the long-term archival of electronic records is PDF/A (ISO 19005), a subset of PDF. PDF/A forbids the use of passwords because it goes against the idea of having the content of PDF documents accessible in the future. In other words, a PDF file with a password cannot be converted to PDF/A. Passwords can be lost or not stored correctly, and in the case of robust passwords that cannot be cracked, all the content is gone forever.
So, what can you do if you need to protect your content that needs to be archived in a compliant way? There are a lot of things you can do.
If your document contains sensitive information, you can (and you must) redact them.
You can also add a watermark and an electronic signature with a timestamp that will prevent future document modifications.

So don’t make the work of hackers easier by following these simple best practices.
Many free tools can hack documents protected with a poor password. You can find them everywhere on the Internet.
Passwords with a low number of characters or made of words are the easiest to crack. The cracking program will use brute force and dictionary attack techniques in these cases. In the first situation, the software will run all combinations of letters and numbers until it gets a match. The shortest the password, the easiest it is to crack. For the latter, the hacking software searches words in various dictionaries. If it were still necessary to say it, isolated words or names are not good choices!
Also, do you know these free quizzes you find on social media to find out the “ten fun facts nobody knows about you” and the like? In these surveys, you’re asked to write down your pet’s name, your mother’s maiden name, your hometown, your firstborn’s date of birth, your favorite song, and so on? These answers could be your password or your answer to the security question when retrieving your password.
So think again that when a friend tags you to answer a survey, and as a rule, beware of requests with “only real friends will do it!”

Other hacking techniques don’t even require cracking software.
Think about phishing, where the user is fooled with an email and prompted to enter his password himself on a fake website. Do not minimize this technique because the latest generation of phishing hackers is quite good, and it’s sometimes challenging to see the difference between the actual form and the fake one.
You can also be hacked by malware without ever giving your password. Thanks to the phishing technique again, hackers want you to click a link in an infected email, an attachment, or an ad on a website. Then, instead of being prompted to a form, a program will be downloaded silently on your device. It will track you when you enter your password somewhere and steal it.
Every day hackers invent more creative ways to steal your information.
Remember, the only way to share a password safely with someone is to tell them face to face. So please don’t write it on paper, don’t send it via email, don’t write it on a chat. Instead, see that person and tell them! Well, and make sure this person stores it safely…
