Java Authentication and Authorization Service, or JAAS, pronounced "Jazz", [1] is the Java implementation of the standard Pluggable Authentication Module (PAM) information security framework. [2] JAAS was introduced as an extension library to the Java Platform, Standard Edition 1.3 and was integrated in version 1.4.
If any check fails on any certificate, the algorithm terminates and path validation fails. (This is an explanatory summary of the scope of the algorithm, not a rigorous reproduction of the detailed steps.) The public key algorithm and parameters are checked; The current date/time is checked against the validity period of the certificate;
For example, in the case of .NET, the developer uses a private key to sign their libraries or executables each time they build. This key will be unique to a developer or group or sometimes per application or object. The developer can either generate this key on their own or obtain one from a trusted certificate authority (CA). [5]
Expiration dates are not a substitute for a CRL. While all expired certificates are considered invalid, not all unexpired certificates should be valid. CRLs or other certificate validation techniques are a necessary part of any properly operated PKI, as mistakes in certificate vetting and key management are expected to occur in real world ...
An EV certificate means a certificate was issued for a domain like example.com, and a company like Example, LLC is the owner of the domain, and the owner was verified by Articles of Incorporation. Extended validation does not add any additional security controls, so the secure channel setup using an EV certificate is not "stronger" than a ...
When the certificate is presented for an entity to validate, they first verify the hash of the certificate matches the reference hash in the white-list, and if they match (indicating the self-signed certificate is the same as the one that was formerly trusted) then the certificate's validity dates can be trusted.
The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded.
The certificate used must match the TLSA record, and it must also pass PKIX certification path validation to a trusted root-CA. A value of 2 is for what is commonly called trust anchor assertion (and DANE-TA). The TLSA record matches the certificate of the root CA, or one of the intermediate CAs, of the certificate in use by the service.
