Description d'origine
La description telle que publiée par la source (souvent en anglais).
A flaw in the curl command line tool's logic makes it only set SSH host verification options when interacting directly using SFTP or SCP, and not as a result of following a redirect. This means --knownhosts, --hostpubsha256, and --hostpubmd5 are never installed when the initial URL is HTTPS. If --location and --proto-redir +sftp is used and the server returns a Location: sftp://example.com redirect, the SFTP connection proceeds without any of the user's requested SSH host verification methods.
