Detailed Description

Interface for creating an RFC 3161 timestamp.

Member Enumeration Documentation

enum StampFlags

Flags for stamp().

Enumerator

sf_dont_check_revocation

Do not check revocation.

Set this flag if you need only the size of the timestamp.

sf_dont_hash

Do not hash the document message digest again.

enum StampResult

Return value of stamp().

Enumerator
sr_ok	Success.
sr_invalid_input	Invalid argument or invalid time-stamp request.
sr_timeout	Timeout.
sr_stopped	Transaction interrupted by stop().
sr_tcp_error	Some failure at the TCP/IP layer.
sr_ssl_error	Some failure at the SSL/TLS layer.
sr_http_error	Some failure at the HTTP layer.
sr_server_error	The server failed to create the time stamp (according to PKIStatus).
sr_invalid_response	The response from the server is invalid.

Constructor & Destructor Documentation

~TimeStamper ( )

inline

Destructor.

TimeStamper ( SIGNDOC_TimeStamper * aP )

inline

Internal function.

Member Function Documentation

const char * getErrorMessage ( ) const

inline

Get an error message for the last stamp() call.

Returns: A pointer to a string describing the reason for the failure of the last stamp() call. The string is empty if the last call succeeded. The pointer is valid until this object is destroyed or stamp() is called again. The string is ASCII encoded, the error message is in English.

const char * getFallbackHashAlgorithmOID ( ) const

inline

Get the object ID of the fallback message digest algorithm.

Returns: A pointer to the object ID of the fallback message digest algorithm as string, e.g., "1.3.14.3.2.26" for SHA-1. The pointer is valid until the object implementing the TimeStamper interface is destroyed.

const char * getHashAlgorithmOID ( ) const

inline

Get the object ID of the message digest algorithm.

Returns: A pointer to the object ID of the message digest algorithm as string, e.g., "1.3.14.3.2.26" for SHA-1. The pointer is valid until the object implementing the TimeStamper interface is destroyed.

SIGNDOC_TimeStamper* getImpl ( )

inline

Internal function.

const SIGNDOC_TimeStamper* getImpl ( ) const

inline

Internal function.

TimeStamper::StampResult stamp	(	const unsigned char *	aHashPtr,
		size_t	aHashSize,
		unsigned	aRandomNonceSize,
		int	aFlags,
		std::vector< unsigned char > &	aOutput,
		int &	aStatus,
		unsigned &	aFailureInfo
	)

inline

Create a time-stamp request, send the request to the configured time stamping authority, and evaluate the response.

The signature in the returned time-stamp token is not verified by this function.

Parameters

[in]	aHashPtr	A pointer to the first octet of the document message digest to be hashed (unless sf_dont_hash is set in aFlags) and signed.
[in]	aHashSize	The size (in octets) of the document message digest pointed to by aHashPtr).
[in]	aRandomNonceSize	The size (in octets, 1 through 256) of the random nonce in the time-stamp request.
[in]	aFlags	Flags modifying the behavior of this function, see enum StampFlags.
[out]	aOutput	The time-stamp token sent by the server will be stored here as blob if this function returns sr_ok. Otherwise, aOutput will be empty.
[out]	aStatus	The PKIStatus value of the response from the server will be stored here. 0 if no response from the server is available.
[out]	aFailureInfo	The PKIFailureInfo value of the response from the server will be stored here. 0 if no response from the server is available.

Returns: sr_ok if successful. Use getErrorMessage() to get an error message.

See also: getErrorMessage(), getHashAlgorithmOID(), stop()

void stop ( )

inline

Interrupt a stamp() call from another thread.

If this function is called while stamp() is waiting for the response from the server, stamp() will return sr_stopped.
