openssl-ts:tldr:d9f23
This command is used to display the details of a timestamp response (TSR) file in a human-readable format using OpenSSL.
Let's break down the command and its arguments:
-
openssl: It is the command-line tool for using the OpenSSL library, which provides cryptographic functionality.
-
ts: This is a subcommand that allows operations related to timestamping.
-
-reply: It is another subcommand that specifies that we are working with a timestamp response.
-
-in ${filename-tsr}: This specifies the input file that contains the timestamp response data. The dollar sign ($) and curly brackets {} are used for variable substitution. Here, the variable "filename-tsr" should be replaced with the actual name of the file.
-
-text: This option tells OpenSSL to display the TSR in a human-readable format, rather than a binary representation.
So, when you execute this command with a valid TSR file, OpenSSL will parse and display the contents of the TSR in a readable format, including information like the timestamp authority, the time of the timestamp, and any additional information contained within the response file.
