JSON Web Token (JWT, suggested pronunciation / dʒ ɒ t /, same as the word "jot" [1]) is a proposed Internet standard for creating data with optional signature and/or optional encryption whose payload holds JSON that asserts some number of claims.
CBOR encoded data is seen as a stream of data items. Each data item consists of a header byte containing a 3-bit type and 5-bit short count. This is followed by an optional extended count (if the short count is in the range 24–27), and an optional payload. For types 0, 1, and 7, there is no payload; the count is the value. For types 2 (byte ...
Field name Index (Bytes) Purpose Start-of-frame: 0: Denotes the start of frame transmission (v1.0: 0xFE) Payload-length: 1: length of payload (n) Packet sequence: 2: Each component counts up their send sequence. Allows for detection of packet loss. System ID: 3: Identification of the SENDING system. Allows to differentiate different systems on ...
JWS can be used for applications in which digitally signed information must be sent in a machine-readable format, such as e-commerce.For example, say a user named Bob is browsing widget prices on a web site (widgets.com), and wishes to get a quote on one of them.
Ed25519 is the EdDSA signature scheme using SHA-512 (SHA-2) and an elliptic curve related to Curve25519 [2] where =, / is the twisted Edwards curve + =, = + and = is the unique point in () whose coordinate is / and whose coordinate is positive.
The smallest CoAP message is 4 bytes in length, if the token, options and payload fields are omitted, i.e. if it only consists of the CoAP header. The header is followed by the token value (0 to 8 bytes) which may be followed by a list of options in an optimized type–length–value format.
In information technology, header is supplemental data placed at the beginning of a block of data being stored or transmitted. In data transmission, the data following the header is sometimes called the payload or body.
As in the SAML 2.0 Technical Overview, [4] the terms subject and principal are used interchangeably in this document. Before delivering the subject-based assertion from IdP to the SP, the IdP may request some information from the principal—such as a user name and password—in order to authenticate the principal.
