Every certified press release includes a verifiable certificate and timestamp that readers can instantly confirm. To verify authenticity: visit https://pkitools.net/pages/timestamp/readtsr.html – upload the provided .tsr
timestamp file, and compare the resulting hash value with the hash published for the linked PDF file. If they match, the press release is authentic and unaltered.
💡 To view the details contained in a .tsr
file (RFC 3161 timestamp), you can also use professional tools such as OpenSSL.
If you have OpenSSL installed on your computer, simply open the terminal and type:
openssl ts -reply -in your_file.tsr -text
This will allow you to read the timestamp date and time, the original hash, the identity of the Time Stamping Authority (TSA), and all the technical information contained in the certificate.
Before diving into the FAQ, here are some key concepts that will help you better understand how CertifiedPressReleases.com works:
What is a hash?
A hash is a unique digital fingerprint of a file or text. Even the smallest change in the file creates a completely different hash. We use the SHA-256 algorithm to guarantee authenticity and integrity.
What is a timestamp?
A timestamp is a digital proof of date and time, issued by a trusted authority under the European eIDAS regulation. It proves when a press release (or any digital file) was created or certified, and prevents backdating or manipulation.
What is a .tsr file?
A .tsr
file (TimeStamp Response) is the official evidence provided by the certification authority. It contains the timestamp, the hash, and the signature of the trusted authority. This is the legally valid proof of certification.
What is a .json file?
A .json
file is a structured text file containing all technical details of the certification, such as the hash, timestamp, and metadata. It is machine-readable and can be verified by forensic experts or legal authorities.
