GitHub - cryptool-org/openssl-webterm: OpenSSL running in browsers, using WebAssembly (Emscripten) + xterm.js + React · GitHub
You can now view the OpenSSL Webterm at https://localhost:4200. The React GUI just builds commands (as strings). These are then called upon the terminal, which is an instance of wasm-webterm. If your browser supports WebWorkers (including SharedArrayBuffers and Atomics), a new Worker thread is spawned and the WebAssembly binary (openssl.wasm) is ran there.

The OpenSSL program can be operated via its Command Line Interface (CLI) which means the terminal. The terminal accepts textual commands, for example openssl genrsa 1024 (which generates a 1024 bit long RSA key).

r/openssl on Reddit: What's the OpenSSL terminal used for? When installing from source it doesn't exist
May 26, 2023 -
Hello
When using the openssl 1.1.1 that comes with Git or XAMPP, then it opens a terminal when I type "openssl":

But when I installed openssl 3.1.0 from source, it just shows a list of commands:
https://imgur.com/a/khWZF1o
What is this terminal used for? And the fact that I don't have it when I built it from source is related to the versions difference? (1.1.1 vs 3.1.0), or because of the way I installed openssl?
thanks

Like lots of command line software, OpenSSL can be used in interactive mode (the prompt you mentioned) or non-interactive mode, in which you give it all the information it needs to run a full command and exit. It’s not surprising that the default behavior would change over time, between dropping you into interactive mode and showing some usage content.

I guess it's not a terminal. But when invoked without parameters, it just does read data from STDIN to do some default operation. Like when you call md5sum without a file name, it reads from STDIN and computes the hash of the data that was entered.

In both cases, the output goes to stdout and nothing is printed to stderr. Additional command line arguments are always ignored. Since for each cipher there is a command of the same name, this provides an easy way for shell scripts to test for the availability of ciphers in the openssl program.

Many commands use an external configuration file for some or all of their arguments and have a -config option to specify that file. The default name of the file is openssl.cnf in the default certificate storage area, which can be determined from the openssl-version(1) command using the -d or -a option.
