Table 252 · Entries in a signature dictionary
ISO 32000-1:2008, §12.8.1 · PDF page 475 ↗
/Filter name
(Required; inheritable) The name of the preferred signature handler to use when validating this signature. If the Prop_Build entry is not present, it shall be also the name of the signature handler that was used to create the signature. If Prop_Build is present, it may be used to determine the name of the handler that created the signature (which is typically the same as Filter but is not needed to be). A conforming reader may substitute a different handler when verifying the signature, as long as it supports the specified SubFilter format. Example signature handlers are Adobe.PPKLite, Entrust.PPKEF, CICI.SignIt, and VeriSign.PPKVS. The name of the filter (i.e. signature handler) shall be identified in accordance with the rules defined in Annex E.
Qualifier: Required; inheritable
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
