What is header digest?

The Digest HTTP header is a response HTTP header that provides the requested resource with a small value generated by a hash function from a whole message. The Digest HTTP header is a response header that provides a digest of the requested resource. The entire representation is used to calculate the digest.

What is the difference between basic authentication and digest authentication?

Digest Authentication communicates credentials in an encrypted form by applying a hash function to: the username, the password, a server supplied nonce value, the HTTP method and the requested URI. Whereas Basic Authentication uses non-encrypted base64 encoding.

What is Passworddigest?

Digest authentication is another authentication type specified in HTTP 1.1. Unlike basic authentication, digest authentication does not require the password to be transmitted. Rather, the client takes the username and password and uses the MD5 hashing algorithm to create a hash, which is then sent to the SQL Server.

What is rfc2617?

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements.

What is digest of URL?

The digest applies to the whole representation of a resource, not to a particular message. It can be used to verify that the representation data has not been modified during transmission.

What is nonce in digest authentication?

Client nonce was introduced in RFC 2617, which allows the client to prevent chosen-plaintext attacks, such as rainbow tables that could otherwise threaten digest authentication schemes. Server nonce is allowed to contain timestamps.

What is the difference between OAuth and OAuth2?

OAuth 2.0 promises to simplify things in following ways: Once the token was generated, OAuth 1.0 required that the client send two security tokens on every API call, and use both to generate the signature. OAuth 2.0 has only one security token, and no signature is required.

What is basic authentication header?

Basic authentication is a simple authentication scheme built into the HTTP protocol. The client sends HTTP requests with the Authorization header that contains the word Basic word followed by a space and a base64-encoded string username:password .

What is nonce in IMS?

nonce is a parameter, which is populated with the Base64 encoding of the concatenation of the AKA authentication challenge RAND, the AKA AUTN token, and optionally some server specific data, as in following diagram from RFC 3310 Figure 1. Base64 Encoding is based on following table defined in RFC 2045 6.8.

What is nonce value in SIP?

Take a look at the Proxy-Authenticate header and you will see a Nonce parameter. Nonce stands for Number Once and is an arbitrary number used only once in a cryptographic communication. The recipient of a Nonce will use it to encrypt his or her credentials.

What is realm in basic auth?

The Basic authentication scheme is based on the model that the client needs to authenticate itself with a user-id and a password for each protection space (“realm”). The realm value is a free-form string that can only be compared for equality with other realms on that server.

What is enable digest authentication?

Digest authentication is a method of authentication in which a request from a potential user is received by a network server and then sent to a domain controller. The domain controller sends a special key, called a digest session key, to the server that received the original request.

What determines the encoding used in the Digest header?

The choice of digest algorithm also determines the encoding to use: for example SHA-256 uses base64 encoding. This header was originally defined in RFC 3230 , but the definition of “selected representation” in RFC 7231 made the original definition inconsistent with current HTTP specifications.

What is the difference between Digest and its API?

Its simple to implement, so your client developers will have less work to do and take less time to deliver, so developers could be more likely to want to use your API Unlike Digest, you can store the passwords on the server in whatever encryption method you like, such as bcrypt, making the passwords more secure

What is the HTTP digest response HTTP header?

The Digest response HTTP header provides a digest of the requested resource. In RFC 7231 terms, this is the selected representation of a resource. The selected representation depends on the Content-Type and Content-Encoding header values, so a single resource may have multiple different digest values.

What is the purpose of digesting data?

The digest of data is the result of some fixed bit length of a one-way hash function that takes the data as input. A digest is sensitive to changes in the corresponding data. Therefore, it serves as a unique and in most cases compacted representation of the original data.
