Struct StandardHandler 

pub struct StandardHandler {
    pub key: Vec<u8>,
    pub method: CryptMethod,
    pub revision: u8,
}

File-level encryption parameters resolved from the trailer’s /Encrypt dictionary. Carries the master key (Algorithm 2 output) plus the per-object cipher selection.

Fields

key: Vec<u8>

File encryption key — n bytes, where n ∈ {5, 16}.

method: CryptMethod

Default crypt method for streams + strings.

revision: u8

Revision (2..=4 supported).

Implementations

impl StandardHandler

pub fn decrypt_object( &self, id: ObjectId, data: &[u8], ) -> Result<Vec<u8>, PdfError>

Decrypt the data of an indirect object whose id is id and whose payload is data (a string body or stream body, after any /Filter decoding). Returns the cleartext bytes.

AESV3 (R=5 / R=6) intentionally ignores id: ISO 32000-2:2020 §7.6.3.1 specifies that for V=5 the file encryption key is fed to AES-256 directly, with no per-object derivation.

pub fn encrypt_object( &self, id: ObjectId, data: &[u8], iv: &[u8; 16], ) -> Result<Vec<u8>, PdfError>

Encrypt the cleartext payload of an indirect object — the inverse of Self::decrypt_object used by the writer to populate /Encrypt- protected strings + streams. RC4 is symmetric (so this re-uses rc4); AES uses a fresh IV which must be embedded as the leading 16 bytes of the ciphertext per §7.6.2.

iv (only consulted for Aes128 / Aes256) lets fixture builders pin the IV for byte-for-byte deterministic outputs. Production callers pass a per-call-randomised IV.
