Function parse_encrypt_dict 

Source 
pub fn parse_encrypt_dict(
    dict: &Dict,
    r: &impl Resolve,
) -> Result<EncryptParams, Error>
Expand description

Read an /Encrypt dictionary into an EncryptParams.

§Errors

Error::UnsupportedHandler for a /Filter other than /Standard, Error::MissingCryptFilter when a named filter is not in /CF, and Error::MalformedEncryptDict or Error::CipherKeyLength when the key length does not resolve. [oracle-bug] naming different filters in /StmF and /StrF is not an error — see EncryptParams::string_cipher.
