Convert TSR to another file type
To convert TSR Data files to another format, you need SignTool or other Encoded software.
Convert a file to TSR
To convert other file formats to the "Time-Stamp Protocol Token" file type, you need software like SignTool or a similar tool.
About TSR files
A .TSR file is primarily a Time-Stamp Protocol Response token defined by the IETF RFC 3161 standard. It is used in cryptography to prove that specific digital data existed at a certain point in time. These files are typically generated by a Time Stamping Authority (TSA) and contain a cryptographically signed timestamp. Other common uses for the .TSR extension include Surveying Data files for Topcon Total Station devices, and Shared Object Repositories in Micro Focus UFT (Unified Functional Testing). The main disadvantage of .TSR files is their lack of readability. Time-Stamp responses are formatted as binary ASN.1 DER encoded structures. You cannot simply open them in a standard text editor or web browser; attempting to do so will display scrambled characters. Users typically need command-line tools like OpenSSL or Microsoft's SignTool to parse and verify the tokens. Similarly, Topcon surveying data requires proprietary software, limiting collaboration with engineers using standard CAD tools. To make the data accessible, users often need to convert .TSR files to human-readable formats like TXT or PEM (for certificates), or CSV and DXF (for Topcon surveying data). However, because these files are either highly specialized cryptographic tokens or proprietary hardware reports, standard online converters usually fail to process them. This file format is difficult to open or convert because the data is intrinsically tied to the software or authority that generated it. Often, only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your TSR file, detects the exact format, and lets you read the text inside.
If you want to convert TSR file to JPG, PDF, PNG, GIF, BMP, TIFF, TIF, WEBP, ICO, CUR, PSD or PSB, you can use SignTool or similar software from the "Digital Certificate Response Token" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to TSR, try SignTool or another comparable tool in the "Digital Certificate Response Token" category.
The TSR Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our TSR converter.
