RFC3161 TimeStamping Verifier

RFC3161 TimeStamping Verifier for cryptographic timestamping verification created by ELPROMA

About Cryptographic Timestamping RFC3161:
Time stamping RFC3161 is an important mechanism for time sealing to data objects as files. It supports any kind of data files incl. JPG, PNG, PDF, DOC, TXT, XLS etc. Size and content of file is not important for timestamping process. The purpose of using RFC3161 timestamping is to be able prove when file was received, made or modified. This is a way to protect Copyright (C) or Intellectual Property. It helps proving to be the first owner. Cryptographic timestamping RFC3161 is also suitable for electronic notarization and other e-services including financial transactions (B2B, B2C, B2G etc).


Verifying:
Verification is requiring pare of files (origina & .tsr stampfile). Verification is not requiring access to TSA. Verification process is similar to Client operation. The first and only step to do is selecting .tsr file produced by Clinet. Please note orginal input file (used at Client operation) must be located in same folder too.


Stamping:
Please select Client for stamping your file. Your orginal files must be located at Device Storage (local mobile phone memory). This Client does not support external memory e.g. SD etc. For timestamping please select your source file.

Once slected input file is TimeStamped according to TSA at https://tsa.elpromaelectronics.com there is output stamp file produced with extention .tsr .The TimeStamp file includes date & time cryptographically sealed (e-signed) by TSA. Please take care to archive all your .tsr target output files together with orginal input data files. Both files creates pare and they are required for future cryptographic verification.
