RFC 5280 defines self-signed certificates as "self-issued certificates where the digital signature may be verified by the public key bound into the certificate" [7] whereas a self-issued certificate is a certificate "in which the issuer and subject are the same entity". While in the strict sense the RFC makes this definition only for CA ...
In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a public key. [ 1 ] [ 2 ] The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the digital signature of ...
# In addition to webrick, we will require webrick/https too for SSL functionalities require 'webrick' require 'webrick/https' # Providing certificate name. This, however, will be a self-generated self-signed certificate cert_name = [ %w[CN localhost] , ] # Enabling SSL and providing the certificate name will instantiate HTTPS server server ...
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 ...
Stunnel relies on the OpenSSL library to implement the underlying TLS or SSL protocol. Stunnel uses public-key cryptography with X.509 digital certificates to secure the SSL connection, and clients can optionally be authenticated via a certificate. [6] If linked against libwrap, it can be configured to act as a proxy–firewall service as well.
The ISRG provides free and open-source reference implementations for ACME: certbot is a Python-based implementation of server certificate management software using the ACME protocol, [6] [7] [8] and boulder is a certificate authority implementation, written in Go. [9] Since 2015 a large variety of client options have appeared for all operating ...
OpenVPN offers pre-shared keys, certificate-based, and username/password-based authentication. Preshared secret key is the easiest, and certificate-based is the most robust and feature-rich. [citation needed] In version 2.0 username/password authentications can be enabled, both with or without certificates. However, to make use of username ...
HTTP Public Key Pinning, announces hash of website's authentic TLS certificate: Public-Key-Pins: max-age=2592000; pin-sha256="E9CZ9INDbd+2eRQozYqqbQ2yXLVKB9+xcprMF+44U1g="; Permanent RFC 7469: Retry-After: If an entity is temporarily unavailable, this instructs the client to try again later.
