Definition in the specification
Table 234 · Entries in a signature field seed value dictionary
ISO 32000-1:2008, §12.7.4.5 · PDF page 455 ↗
/Filter name
(Optional) The signature handler that shall be used to sign the signature field. Beginning with PDF 1.7, if Filter is specified and the Ff entry indicates this entry is a required constraint, then the signature handler specified by this entry shall be used when signing; otherwise, signing shall not take place. If Ff indicates that this is an optional constraint, this handler may be used if it is available. If it is not available, a different handler may be used instead.
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
