Struct StandardSecurityHandler 

pub struct StandardSecurityHandler { /* private fields */ }

Implementations

impl StandardSecurityHandler

pub fn open( encrypt_dict: &PdfDictionary, id_first: &[u8], password: &[u8], ) -> PdfResult<Option<Self>>

Builds a decryption handler from the /Encrypt dictionary and the trailer’s first /ID string, authenticating the supplied password. Returns None if the password does not authenticate.

pub fn from_file_key( file_key: Vec<u8>, string_method: CryptMethod, stream_method: CryptMethod, encrypt_metadata: bool, ) -> Self

Builds a handler from an externally-derived file key and the pre-resolved crypt methods. Used by credential paths that derive the file key out-of-band — the public-key handler unwraps the file key from a CMS recipient envelope and then constructs the handler via this entry point rather than open.

pub fn encrypts_metadata(&self) -> bool

Returns true when this handler was configured with /EncryptMetadata false. Parser uses this to skip /Type /Metadata streams.

pub fn decrypt_bytes( &self, bytes: &[u8], object_ref: ObjectRef, kind: BytesKind, ) -> PdfResult<Vec<u8>>

Decrypts bytes produced for the indirect object (num, gen). The crypt method is chosen per kind — strings use /StrF, streams use /StmF. Returns the ciphertext unchanged for /Identity filters; returns an error for malformed AES input (wrong length, bad PKCS#7 padding).
