How to Edit Encrypted PDF File without Open Password

Many programs provide us password settings to encrypt PDF files. However, they don’t tell us how to decrypt them when we have to edit encrypted PDF files but PDF password forgot or lost. So what can we do if we also encounter the same problem?

In order to protect PDF file better, I think PDF program, such as Adobe Acrobat would not provide a way to edit encrypted PDF file without password. We need to find other methods by ourselves.
