How good is PDF password protection?
We are encrypts the document using the encryption algorithm with a 128-bit key size. Assuming that one could build a machine that could recover a key in a second, then it would take that machine approximately 149 thousand-billion (149 trillion) years to crack a 128-bit key.
To create a strong password, increase the length of the password and add a mix of letters (both upper and lower case) and numbers. The addition of symbols can also increase password strength. When you enter passwords, avoid using personal information or common words found in a dictionary that can be guessed more easily.
