This protocol supports X.509 for authentication. TLS is the protocol used to establish encrypted network connections between web-browsers and servers. This certificate (along with the private key) is then used to prove the identity over a network connection. After some identity vetting process, an organisation (known as the certification authority) will issue a certificate, which contains the public key and some identity information. Asymmetric encryption means each identity has two keys: the public key and the private key.
X.509 is a technology that uses asymmetric encryption for authentication. To counter this problem, by default dCache will reject all basic authentication if the connection is unencrypted, with only URLs starting being accepted. Anyone who is able to capture the network traffic will learn the username and password, and the user’s account is compromised.

If basic authentication is used with an unencrypted request (a URL starting with then the password will be sent unencrypted over the network. curl -u paul Īlthough this approach is very simple and widely supported by clients, it relies on the network connection to encrypt the content. The following example shows curl using Basic authentication, prompting the user to enter their password. It involves the client sending the username and complete password to dCache. Basicīasic authentication is the simplest scheme. Please note that the actual authentication supported by any specific dCache instance is controlled by the server’s configuration, so you may not have access to all these authentication options. This section describes the different authentication options that dCache supports. When using TLS-based authentication, the client makes requests without any Authorization HTTP request headers.
This allows the client to authenticate without revealing all information, allowing the authentication to take place before the encrypted connection is established. Unlike bearer tokens, this process is iterative. During this TLS handshake, the client can authenticate. After establishing the TCP connection, a TLS handshake takes place to ensure the connection is encrypted. SSL/TLS authentication, in contrast to Authorization header authentication, happens before the HTTP requests. Encryption is mandatory when using bearer tokens however, even with transport encryption (such as SSL/TLS), bearer tokens are inherently risky, and often use restrictions to reduce the impact should they be stolen. This is simpler than the alternatives, but comes at a cost: any agent able to observe the HTTP request has the token and can subsequently impersonate the valid client. Several of these options are available to dCache clients.īroadly speaking there are two ways of authenticating: the Authorization HTTP request header (which often uses some bearer token) and through SSL/TLS.Ī bearer token is a token that requires no interaction to authenticate: supplying the token as part of the request is sufficient. HTTP is very flexible in how it handles authentication, with may different ways a client can prove its identity.

Perhaps the most common is password based authentication, where the client proving to the server that it knows some secret code supplied by the user. AuthenticationĪuthentication is the process where the client proves the identity of the user.
Other clients should also work and you should not read these choices as an endorsement of those clients over others. In this chapter, we will use curl to illustrate most HTTP operations, and rclone as a specific WebDAV client. Although WebDAV is less popular, there are still many clients from which you can choose.

In simple terms, HTTP allows a client to upload, download and delete files, while WebDAV allows filesystem-like operations, such as to rename files and list directory contents.ĭue to its overwhelming popularity, there are many HTTP clients. Web Distributed Authoring and Versioning (WebDAV) is an extension of the Hypertext Transfer Protocol (HTTP) that allows clients to perform remote Web content authoring operations.
