Technical Insight: Decrypting PDF Encryption Dictionaries
Protected PDFs use standard security handlers (RC4 or AES algorithms) defined in the document's encrypt dictionary. When you upload a locked file, pdf-lib checks the header and returns an encryption flag. When you input the password, the local script uses it as a key to decrypt the PDF's object streams. Once decrypted, we save the document with the encryption metadata removed. The new file is compiled without security headers and downloaded, keeping your passwords locally protected.
