Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
A value of 1 is for what is commonly called service certificate constraint (and PKIX-EE). 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 ...
OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites.
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 ...
Convergence was a proposed strategy for replacing SSL certificate authorities, first put forth by Moxie Marlinspike in August 2011 while giving a talk titled "SSL and the Future of Authenticity" at the Black Hat security conference. [1] It was demonstrated with a Firefox addon and a server-side notary daemon.
Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. [1] Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works.
In cryptography, a client certificate is a type of digital certificate that is used by client systems to make authenticated requests to a remote server. [1] Client certificates play a key role in many mutual authentication designs, providing strong assurances of a requester's identity.
