TimestampInfo Type

A container for timestamp information.

Remarks

The TimestampInfo object contains details of a third-party timestamp and the outcome of its validation.

Accuracy
long

This field indicates the accuracy of the included time mark, in microseconds.

Bytes
byte[]

Returns raw timestamp data in DER format.

ChainValidationDetails
int

The details of a certificate chain validation outcome. They may often suggest what reasons that contributed to the overall validation result.

Returns a bit mask of the following options:


cvrBadData	`0x0001`	One or more certificates in the validation path are malformed
cvrRevoked	`0x0002`	One or more certificates are revoked
cvrNotYetValid	`0x0004`	One or more certificates are not yet valid
cvrExpired	`0x0008`	One or more certificates are expired
cvrInvalidSignature	`0x0010`	A certificate contains a non-valid digital signature
cvrUnknownCA	`0x0020`	A CA certificate for one or more certificates has not been found (chain incomplete)
cvrCAUnauthorized	`0x0040`	One of the CA certificates are not authorized to act as CA
cvrCRLNotVerified	`0x0080`	One or more CRLs could not be verified
cvrOCSPNotVerified	`0x0100`	One or more OCSP responses could not be verified
cvrIdentityMismatch	`0x0200`	The identity protected by the certificate (a TLS endpoint or an e-mail addressee) does not match what is recorded in the certificate
cvrNoKeyUsage	`0x0400`	A mandatory key usage is not enabled in one of the chain certificates
cvrBlocked	`0x0800`	One or more certificates are blocked
cvrFailure	`0x1000`	General validation failure
cvrChainLoop	`0x2000`	Chain loop: one of the CA certificates recursively signs itself
cvrWeakAlgorithm	`0x4000`	A weak algorithm is used in one of certificates or revocation elements
cvrUserEnforced	`0x8000`	The chain was considered invalid following intervention from a user code

ChainValidationResult
int

The outcome of a certificate chain validation routine.

Available options:


cvtValid	`0`	The chain is valid
cvtValidButUntrusted	`1`	The chain is valid, but the root certificate is not trusted
cvtInvalid	`2`	The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature)
cvtCantBeEstablished	`3`	The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses)

Use the ValidationLog property to access the detailed validation log.

HashAlgorithm
String

Returns the timestamp's hash algorithm

SerialNumber
byte[]

Returns the timestamp's serial number.

Time
String

The time point incorporated into the timestamp.

TimestampType
int

Returns the timestamp type.

Available options:


tstUnknown	`0`
tstLegacy	`1`	Supported by: AuthenticodeVerifier
tstTrusted	`2`	Supported by: AuthenticodeVerifier
tstGeneric	`3`	Supported by: CAdESVerifier
tstESC	`4`	Supported by: CAdESVerifier

tstArchive2	`8`	Archive v2 timestamp. Supported by: CAdESVerifier
tstArchive3	`9`	Archive v3 timestamp. Supported by: CAdESVerifier
tstIndividualDataObjects	`10`	Supported by: OfficeVerifier, SOAPVerifier, XAdESVerifier
tstAllDataObjects	`11`	Supported by: OfficeVerifier, SOAPVerifier, XAdESVerifier
tstSignature	`12`	Signature timestamp. Supported by: OfficeVerifier, SOAPVerifier, XAdESVerifier
tstRefsOnly	`13`	RefsOnly timestamp. Supported by: OfficeVerifier, SOAPVerifier, XAdESVerifier
tstSigAndRefs	`14`	SigAndRefs timestamp. Supported by: OfficeVerifier, SOAPVerifier, XAdESVerifier

TSAName
String

This value uniquely identifies the Timestamp Authority (TSA).

This property provides information about the entity that manages the TSA.

ValidationLog
String

Contains the TSA certificate chain validation log. This information is extremely useful if the timestamp validation fails.

ValidationResult
int

Contains timestamp validation outcome.

Use this property to check the result of the most recent timestamp validation.


svtValid	`0`	The signature is valid
svtUnknown	`1`	Signature validity is unknown
svtCorrupted	`2`	The signature is corrupted
svtSignerNotFound	`3`	Failed to acquire the signing certificate. The signature cannot be validated.
svtFailure	`4`	General failure

public TimestampInfo();

Creates a new TimestampInfo object with default field values.
