This security weakness is taken advantage of by Elcomsoft’s PDF password removal software among others.
Though Adobe has updated its encryption algorithms and key lengths several times, fundamental flaws exist in its password-based implementation. For better or for worse, the security mechanism has persisted since.

Just four years later however it was cracked by a Russian security engineer working for Elcomsoft. The password and encryption combination became immediately popular, and understandably so it was all businesses had at the time. It wasn’t until 1996 that Adobe released a version that included passwords, and a few years later digital signatures and RC4 encryption. As such, on its release in 1993, the Adobe PDF format didn’t ship with any form of PDF protection. When PDFs were developed in the 1990s, the priority wasn’t security – it was on making the document format as shareable as possible.

Below we cover how to password protect PDF files, and the ways that users can easily remove that protection. The best way is to call the recipient of the Zip file and convey the password over the phone.Some might argue that password protecting PDF files has its uses, but protecting confidential and sensitive business information is not one of them. Meaning that you send the file and the password by different communication channels one on the internet, and one not. Passwords must be shared via out of band.
**IMPORTANT** – Do not share a password via email. The new archive file will be located in the same folder as the original. Step 7: Select “Ok” to create the encrypted archive file. Use a strong password with at least 8 characters containing upper and lowercase letters, and a minimum of one number. It is strongly recommended to use AES-256 to protect sensitive and confidential data. Selecting ZipCrypto may allow users to open the zip file in Windows without a zip program, but it does not provide adequate protection against attackers with modern cracking tools. AES-256 is proven much more secure than ZipCrypto, but if you select AES-256 the recipient of the zip file may have to install 7-zip or another zip program to read the file contents. There is a trade-off between using AES-256 and ZipCrypto. Step 5: Change the Encryption Method to “AES-256”. Step 4: Change the Archive format to “Zip”. Step 3: In the Add to Archive window change the name of the archive you wish to create. Step 2: Select “7-Zip” then “Add to archive…” Step 1: Right click on the file / folder to be encrypted. Once the software is installed, please follow these steps to encrypt a file or folder. To obtain a copy of 7-Zip, please see and select the appropriate Download link. 7-Zip is a free software that creates Zip files that can be opened with WinZip or other similar programs. That archive can be encrypted and protected with a password. When you send or transfer files that contain Personal Identifiable Information (PII) or other confidential and sensitive data, the files must be encrypted to ensure they are protected from unauthorized disclosure.ħ-Zip, like WinZip, creates a container called archive that holds the files to be protected. 7-Zip is an open source software used to compress or zip files secured with encryption.
