Keycloak is an open-source software product to allow single sign-on with identity and access management aimed at modern applications and services. Until April 2023, this WildFly community project was under the stewardship of Red Hat , who use it as the upstream project for their Red Hat build of Keycloak .
This means that one can use the key pair to get a certificate from any certificate authority, when one has access to the private key. Also the user can pin public keys of root or intermediate certificates (created by certificate authorities), restricting site to certificates issued by the said certificate authority.
Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously ...
The PKI creates digital certificates that map public keys to entities, securely stores these certificates in a central repository and revokes them if needed. [8] [9] [10] A PKI consists of: [9] [11] [12] A certificate authority (CA), which stores, issues and signs the digital certificates;
In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. [ 1 ] Key
UMA does not use or depend on OpenID 2.0 as a means of user identification. However, it optionally uses the OAuth-based OpenID Connect protocol as a means of collecting identity claims from a requesting party in order to attempt to satisfy the authorizing user's access policy. [citation needed]
Once a user has accepted another user's fingerprint, that fingerprint (or the key it refers to) will be stored locally along with a record of the other user's name or address, so that future communications with that user can be automatically authenticated. In systems such as X.509-based PKI, fingerprints are primarily used to authenticate root ...
Identity-based systems have a characteristic problem in operation. Suppose Alice and Bob are users of such a system. Since the information needed to find Alice's public key is completely determined by Alice's ID and the master public key, it is not possible to revoke Alice's credentials and issue new credentials without either (a) changing Alice's ID (usually a phone number or an email address ...
