PDF supports encryption with RC4 and AES with different password derivation functions. The comment on the decrypt
function is wrong, it is possible to decrypt AES-encrypted documents.
Regarding the PDF encryption methods, the most common PDF readers support both RC4 and AES. Some readers may not support the latest password derivation algorithm though (it is only used if you pass the hardened: true
option to the encrypt method).
