   Encryption and Decryption of PDFs PDF encryption makes use of RC4 and AES algorithms with different key length. pypdf supports all of them until PDF-2.0, which is the latest PDF standard. pypdf use an extra dependency to do encryption or decryption for AES algorithms. We recommend pyca/cryptography. Alternatively, you can use pycryptodome.

   Which encryption algorithm should pypdf use?

   • We recommend using AES-256-R5. pypdf uses RC4 by default for compatibility if you omit the “algorithm” parameter. Since RC4 is insecure, you should use AES algorithms. You can decrypt a PDF using the appropriate password:

   Does pypdf use RC4 encryption?

   • Please see the note in the installation guide for installing the extra dependencies if interacting with PDFs that use AES. ⚠️ WARNING ⚠️: pypdf uses by default RC4 encryption if you ommit the “algorithm” parameter. This encryption algorithm is insecure. The more modern and secure AES encryption requires pycryptodome to be installed.
