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 ...
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 ...
C programs can use Rustls through a foreign function interface API, rustls-ffi. [ 3 ] [ 6 ] For example, cURL is a popular tool written in C, and it allows using Rustls through rustls-ffi . [ 25 ] [ 26 ] Rustls also has an OpenSSL compatibility layer that allows configuring the widely-used Nginx web server to use Rustls instead of OpenSSL.
A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity. The PKI creates digital certificates which map public keys to entities, securely stores these certificates in a central repository and revokes them ...
FIPS 140 is a U.S. Federal program for the testing and certification of cryptographic modules. An early FIPS 140-1 certificate for OpenSSL's FOM 1.0 was revoked in July 2006 "when questions were raised about the validated module's interaction with outside software." The module was re-certified in February 2007 before giving way to FIPS 140-2. [42]
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.
cryptlib is a security toolkit library that allows programmers to incorporate encryption and authentication services to software. It provides a high-level interface so strong security capabilities can be added to an application without needing to know many of the low-level details of encryption or authentication algorithms.
Botan is a BSD-licensed cryptographic and TLS library written in C++11.It provides a wide variety of cryptographic algorithms, formats, and protocols, e.g. SSL and TLS.It is used in the Monotone distributed revision control program, the OpenDNSSEC system, and ISC's Kea DHCP server among other projects.
