/SubFilter name
(Optional) A name that describes the encoding of the signature value and key information in the signature dictionary. A conforming reader may use any handler that supports this format to validate the signature. (PDF 1.6) The following values for public-key cryptographic signatures shall be used: adbe.x509.rsa_sha1, adbe.pkcs7.detached, and adbe.pkcs7.sha1 (see 12.8.3, “Signature Interoperability”). Other values may be defined by developers, and when used, shall be prefixed with the registered developer identification. All prefix names shall be registered (see Annex E). The prefix “adbe” has been registered by Adobe Systems and the three subfilter names listed above and defined in 12.8.3, “Signature Interoperability“ may be used by any developer.
Qualificateur : Optional
