A hint indicating which key the client used to generate the token signature. The server will match this value to a key on file in order to verify that the signature is valid and the token is authentic. x5c: x.509 Certificate Chain A certificate chain in RFC4945 format corresponding to the private key used to generate the token signature.
The underlying cryptographic operations are performed by an authenticator, which is an abstract functional model that is mostly agnostic with respect to how the key material is managed. This makes it possible to implement support for WebAuthn purely in software, making use of a processor's trusted execution environment or a Trusted Platform ...
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. Then widgets.com could provide Bob with a JWS object containing all relevant information about the widget, including the price, then sign it using their private key.
Enables OAuth 2.0 implementations to apply Token Binding to Access Tokens, Authorization Codes, Refresh Tokens, JWT Authorization Grants, and JWT Client Authentication. This cryptographically binds these tokens to a client's Token Binding key pair, possession of which is proven on the TLS connections over which the tokens are intended to be used.

Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can ...
In contrast, EdDSA chooses the nonce deterministically as the hash of a part of the private key and the message. Thus, once a private key is generated, EdDSA has no further need for a random number generator in order to make signatures, and there is no danger that a broken random number generator used to make a signature will reveal the private ...
Security token service (STS) is a cross-platform open standard core component of the OASIS group's WS-Trust web services single sign-on infrastructure framework specification. cf. [1] [2] Within that claims-based identity framework, a secure token service is responsible for issuing, validating, renewing and cancelling security tokens.
