Definition in the specification
Table 25 · Entries common to all crypt filter dictionaries
ISO 32000-1:2008, §7.6.5 · PDF page 76 ↗
/Length integer
(Optional) The bit length of the encryption key. It shall be a multiple of 8 in the range of 40 to 128. Security handlers may define their own use of the Length entry and should use it to define the bit length of the encryption key. Standard security handler expresses the length in multiples of 8 (16 means 128) and public-key security handler expresses it as is (128 means 128).
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
