Implementations

impl EncryptionState

pub fn try_open( encrypt_dict: &PdfDict, trailer: &PdfDict, file_id: &[u8], ) -> Result<Self, PdfError>

Try to decrypt with an empty user password. Equivalent to try_open_with_password(..., b""). Returns Err(PdfError::PasswordRequired) if the empty password does not match; callers that want to try a user-supplied password should use Self::try_open_with_password instead.

pub fn try_open_with_password( encrypt_dict: &PdfDict, _trailer: &PdfDict, file_id: &[u8], password: &[u8], ) -> Result<Self, PdfError>

Try to decrypt with the given user password. Returns Ok(state) on success and Err(PdfError::PasswordRequired) when the password doesn’t match.

pub fn decrypt_string(&self, data: &[u8], obj_num: u32, gen_num: u16) -> Vec<u8>

Decrypt a string.

pub fn decrypt_stream(&self, data: &[u8], obj_num: u32, gen_num: u16) -> Vec<u8>

Decrypt a stream.
