Enum CryptClass 

pub enum CryptClass {
    Stream,
    String,
    Embedded,
}

Which crypt filter class a payload belongs to.

Stream and String resolve to one cipher because PDFium refuses a document whose /StmF and /StrF differ (Divergence D1). Embedded is the one class that can genuinely name another cipher — see crate::SecurityHandler::embedded_cipher and the [oracle-bug] note on standard::embedded_cipher, which records that the oracle reads /EFF nowhere. Only the cipher differs: ISO 32000-1 §7.6.5 gives every /CF entry the same file encryption key.

Variants

Stream

A stream’s data, governed by /StmF.

String

A string object, governed by /StrF.

Embedded

An embedded file stream, nominally governed by /EFF.
