Configure the timestamping policy for generating timestamp responses.
Mandatory: Yes.
Accuracy
The allowed deviation from the genTime generation time of the timestamp response.
Mandatory: No. When omitted, this optional value is not present in the TSTInfo response field.
Allowed hash algorithms
The list of allowed hash algorithms. Supported values are:
- sha1
- sha224
- sha256
- sha384
- sha512
The Timestamping Authority solution will not timestamp data hashed with other algorithms.
Mandatory: No. This optional value defaults to the following list.
- sha224
- sha256
- sha384
- sha512
Ordering
Check to sort timestamps based on the genTime field, regardless of the accuracy of the genTime generation time in the timestamp response.
Mandatory: No. This option is disabled by default.
Policy ID
The identifier of the timestamping policy.
Mandatory: Yes.
Qualified timestamp extension
Check this box to add a qcStatements statement with the esi4-qtstStatement-1 extension as required for qualified electronic timestamps.
Mandatory: No. This optional value defaults to false (unchecked).
Serial number length
The allowed length in bytes of the timestamp serial numbers, as a number in the 8-20 range.
Mandatory: No. This optional value defaults to 8 bytes.
Signature digest algorithm
The algorithm for hashing the timestamped data.
The selected algorithm must be included in the Allowed hash algorithms list.
Mandatory: No. This optional value defaults to "sha256".
