What is a REQ file?
A REQ file is a file used in the process of setting up a digital certificate. It stores a Certificate Signing Request (CSR), which includes information that uniquely identifies the initiator of the request. REQ files are sent to trusted entities (certificate authorities) who use the requests to generate valid digital certificates for the requesters.
CSRs are used in the process of public key cryptography, which is used to validate identities on the Internet. Digital certificates validate the authenticity of a company or merchant online so users or customers can know that the website is trustworthy and secure.
