Estonian DDOC re-timestamping utility
TeRa is a part of Estonian national ID-card software developed by
CGI on behalf of governmental institution - Estonian Information System’s Authority.
TeRa utility allows you to search local *.ddoc files and timestamp them into *.asics container.
*.ddoc files used SHA-1 hash that might soon be attacable. TeRa
timestamps found *.ddoc files using SHA-256 and encapsulates them
into *.asics container ensuring its validity. No signature is
added to the container so signature information has to be
retreived from the encapsulated *.ddoc file (original *.ddoc
file is copied into *.asics untouched).
