A
complex data type that is used to store the results of the Get Signature operation operation that the Signature service provides.
It contains the signature and information about the filter and subfilters
that are used for validating the signature embedded in the PDF document.
For information about data that can be accessed using Xpath Expressions,
see Data items.
Data itemsThe data items that PDFSignature variables
contain.
certificatesA list of byte values
that represents the certificates that are embedded in the PDF document
at the time of signing.
contentsA list of byte values
that represents the actual signature value in the form of a DER-encoded
PKCS#1 or PKCS#7. If subfilter is set as adbe.pkcs7.detached or
adbe.pkcs7.sha1, the PKCS#7 packet contains the embedded certificates.
CRLsA list of byte values
that represents Certificate Revocation List (CRL) information.
filterA string value
that represents the name of the preferred signature handler to use
for validating the signature. For example, preferred signature handlers
can be Adobe.PPKLite, Entrust.PPKEF, CICI.SignIt, and VeriSign.PPKVS.
OCSPResponsesA list of byte values
that contains information returned from the Online Certificate Status
Protocol (OCSP) server.
subFilterA string value
that represents the encoding to use when signing the PDF form. These
values are valid:
- adbe_pkcs7_detached:
- No data is encapsulated in the PKCS#7-signed data field.
- adbe_pkcs7_sha1:
- The adbe.pkcs7.sha1 digest of the byte range is encapsulated
in the PKCS#7-signed data field.
- adbe_x509_rsa_sha1:
- The adbe.x509.rsa.sha1 digest uses the RSA encryption algorithm
and SHA-1 digest method.
timestampA list of byte values
that contains information returned from the time-stamping provider
(TSP).
