This property enables you to specify the hash algorithm to be
used for timestamp requests using your desired Time Stamping
In signature workflows there may be a number of different
- The signature itself may be timestamped as with PAdES B_T
- An optional timestamp entry (/TS) may be added to the /VRI
entry in the Document Security Store (DSS) for PAdES B_LT.
- A document timestamp is a special form of signature certifying
the document at a particular time, as with PAdES B_LTA
For convenience when a signature is created with SignatureCompliance set to a level above
PAdES_B_B this value is used to compute the digests for all
required timestamping operations.
Note that MD5 or SHA1 should not be used where PAdES conformance
It is unlikely that you would need to change this from the
default Oid for SHA256.
