  dcterms:description "Timestamp Reply (.tsr) files are binary files that are a component of digital signature verification processes that are run through TSAs (Time Stamp Authorities), where a timestamp reply is a response to a timestamp message, containing both the original timestamp and the response timestamp. TSR files were developed as early as 1989 through the Internet Engineering Task Force (IETF) to address Internet Control Message Protocol issues in communication layers between users and Internet hosts. Timestamp Reply files differ from .tsq files in that they are only created in response to a timestamp query. TSR is an open file format and is generally adopted by technologies utilizing OpenSSL, and may be found in social media archiving packages such as those created using ArchiveSocial. Without further testing, Timestamp Reply files should be retained for future assessment." ;
