3.5 Encryption 14

Modify Table 3.18 as shown below where only entries that changed are listed in the table. The

entry has a new

value of 5; the only change to the other listed entries (

StmF

StrF

, and

EFF

) is to qualify them for use when

. Unchanged text is shown in gray.

TABLE 3.18 Entries common to all encryption dictionaries

KEY

TYPE

DESCRIPTION

number

(

Optional but strongly recommended

) A code specifying the algorithm to

be used in encrypting and decrypting the document:

, An algorithm that is undocumented and no longer supported, and

whose use is strongly discouraged.

Old files may use this value but

no new files should be written using 0.

, Algorithm 3.1 on page 119, with an encryption key length of 40

bits; see below.

, (PDF 1.4) Algorithm 3.1, but permitting encryption key lengths

greater than 40 bits.

, (PDF 1.4) An unpublished algorithm that permits encryption key

lengths ranging from 40 to 128 bits; see implementation note 22 in
Appendix H.

, (PDF 1.5) The security handler defines the use of encryption and

decryption in the document, using the rules specified by the

StmF

, and

StrF

entries

using algorithm 3.1 with a key length of 128

bits.

5, (

ExtensionLevel 3

) The security handler defines the use of

encryption and decryption in the document, using the rules
specified by the

StmF

, and

StrF

entries using algorithm 3.1a

with a key length of 256 bits.

The default value if this entry is omitted is 0, but a value of 1 or greater is
strongly recommended.

(See implementation note 23 in Appendix H.)

StmF

name

(

Optional; meaningful only when the value of

or 5 for

ExtensionLevel 3

) The name of the crypt filter that is used by default

when decrypting streams. The name must be a key in the

dictionary

or a standard crypt filter name specified in Table 3.23. All streams in the
document, except for cross-reference streams (see Section 3.4.7,
“Cross-Reference Streams”) or streams that have a

Crypt

entry in their

Filter

array (see Table 3.5), are decrypted by the security handler,

using this crypt filter.

Default value: Identity.
