Extract text from Time-stamp requests (TSQ)
To convert TSQ requests to another format, you need OpenSSL or other Encoded software.
To convert other file formats to the "Security Request File" file type, you need software like OpenSSL or a similar tool.
A .tsq file is a Time-Stamp Protocol request file based on the IETF RFC 3161 standard. Developers and system administrators use it to ask a Time Stamping Authority (TSA) to provide cryptographic proof that a specific piece of data existed at a specific time. You can generate and open these files using command-line tools like OpenSSL. They are heavily used in Public Key Infrastructure (PKI) and digital signature workflows.
The main disadvantage of the .tsq format is that it is a binary ASN.1 structure encoded in DER format. If you try to open it in a standard text editor, you will only see unreadable characters. Because it requires specialized command-line utilities to parse, average users find it very difficult to inspect the contents. To view the data, you usually need to convert or decode the .tsq file into a plain text format (TXT) or a Base64-encoded PEM file. This allows you to read the hash algorithm, the message imprint, and the nonce values.
Because this is a specialized cryptographic binary format, standard online converters fail to process it. Often, only the original cryptographic software can properly read or export the data. Our platform can inspect the file and show text or internal content. If our analysis detects a supported underlying or embedded format - even if your file is one of the rare alternatives like a Capcom game music sequence or an Elspec PQSCADA data file - viewing or conversion may still be possible.
Convert.Guru analyzes your TSQ file, detects the exact format, and lets you read the text inside.
Users also converted VTK, TFT and MPH files.
If you want to convert TSQ file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use OpenSSL or similar software from the "Cryptographic Timestamp Request" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to TSQ, try OpenSSL or another comparable tool in the "Cryptographic Timestamp Request" category.
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 TSQ converter.
