With the TspClientSocket which extends the java.net.Socket and the TspSSLClientSocket which extends the iaik.security.ssl.SSLSocket it is very easy to connect to a RFC 3161 compliant TSP Server. Once you are connected you can send a request and receive the corresponding response within one method invocation.

Main Features:

Written purely in the Java™ language implementation of the time stamp protocol (IETF RFC-3161)
SigningCertificateV2 and ESSCertIDv2 support according to IETF RFC-5816
Encoding and decoding of time stamp requests
Encoding and decoding of time stamp responses and accessing the contained information
Verifying digital signatures of time stamp tokens
Works on JDK Versions 1.2, 1.3, 1.4, 1.5, 1.6, 1.7 and compatible
All data types which are defined as ASN.1 structures in the RFC 3161 are implemented as separate classes with full control and access for the developer
Sample code of TCP/IP, SSL and HTTP-based TSP server and clients
