A major new requirement in v2 is that requests for wildcard certificates require the modification of a Domain Name Service TXT record, verifying control over the domain. Changes to ACME v2 protocol since v1 include: [13] The authorization/issuance flow has changed; JWS request authorization has changed
In public key infrastructure (PKI) systems, a certificate signing request (CSR or certification request) is a message sent from an applicant to a certificate authority of the public key infrastructure (PKI) in order to apply for a digital identity certificate. The CSR usually contains the public key for which the certificate should be issued ...
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.
An Extended Validation (EV) Certificate is a certificate conforming to X.509 that proves the legal entity of the owner and is signed by a certificate authority key that can issue EV certificates. EV certificates can be used in the same manner as any other X.509 certificates, including securing web communications with HTTPS and signing software ...
This reversible status can be used to note the temporary invalidity of the certificate (e.g., if the user is unsure if the private key has been lost). If, in this example, the private key was found and nobody had access to it, the status could be reinstated, and the certificate is valid again, thus removing the certificate from future CRLs.
It allows the presenter of a certificate to bear the resource cost involved in providing Online Certificate Status Protocol (OCSP) responses by appending ("stapling") a time-stamped OCSP response signed by the CA (certificate authority) to the initial TLS handshake, eliminating the need for clients to contact the CA, with the aim of improving ...
A number of workarounds were developed to locally disable the effects of Site Finder on a per-network basis. Most notably, the Internet Systems Consortium announced that it had produced a version of the BIND DNS software that could be configured by Internet service providers to filter out wildcard DNS from certain domains; this software was deployed by a number of ISPs.
Similarly to the Certificate Management Protocol (CMP), it can be used for obtaining X.509 digital certificates in a public key infrastructure (PKI). CMS is one of two protocols utilizing the Certificate Request Message Format (CRMF), described in RFC 4211 , with the other protocol being CMP.
