curltyökalun

Curltyökalun, often referred to as cURL, is a command-line tool and library for transferring data with URLs. It supports a wide range of protocols, including HTTP, HTTPS, FTP, FTPS, SCP, SFTP, and more. Developed by Daniel Stenberg, cURL is widely used by developers and system administrators for testing web services, debugging network requests, and automating data transfers.

The primary function of cURL is to send requests to a server and receive responses. It can be used to fetch web pages, download files, interact with APIs, and perform various other network operations. Its versatility allows users to specify different HTTP methods (GET, POST, PUT, DELETE, etc.), set custom headers, send data in request bodies, and handle cookies.

cURL is available for most operating systems, including Linux, macOS, and Windows. It can be installed as a standalone application or integrated into other programs through its libcurl library. The command-line interface is extensive, offering numerous options to control every aspect of a data transfer. This makes it a powerful tool for scripting and automation tasks.

Beyond simple data retrieval, cURL can also be used for more complex scenarios. It supports authentication methods like basic, digest, and NTLM. It can manage SSL/TLS certificates for secure connections and proxy servers for network routing. Its capabilities make it an indispensable tool in the modern development and operations landscape.
