What is PKI, HTTPS, SSL, TLS?

The content provided here includes PKI related topics, including PKI, HTTPS, SSL, TLS, and others. A Public Key Infrastructure (PKI) is essential for encrypting the web and establishing trust among the thousands, millions, should I say billions of clients and servers on the internet? To further teach on and influence encrypting the web, posts will be dedicated to encryption, the secure HTTP (s) protocol, SSL and TLS, openssl, and digital certificates.

Short glossary:


PKI – A public key infrastructure provides a way to encrypt the web with digital certificates and manage the lifecycle of the certificates, including enrollment, revocation, and expiration.
HTTPS – HTTPS is the secure version of the HTTP protocol, providing encryption of HTTP traffic with digital certificates issued by a PKI.
SSL – The Secure Sockets Layer is a standard for providing encryption between two entities (client and server). It is the secure protocol providing secure HTTP(s).
TLS – Transport Layer Security is the most recent version of the SSL standard/protocol.
Encryption – Encryption is simply the translation of plain text data into secret data. Asymmetric encryption (using public and private key pair) is used by PKI to encrypt the web. Symmetric encryption, on the other hand, uses one shared secret key to both encrypt and decrypt data.
Digital Certificate – A digital certificate, most commonly an X.509 certificate, is issued by Certification Authorities (CA) containing the public key of a key pair. This certificate is installed on web servers or in client code depending on the use case and can be used to identify a server or be used for client authentication.
Certification Authority – In simple terms, a Certification Authority (CA) is an entity that issues the digital certificates. Many CAs are publicly trusted, but many uses are for private CA’s for in house purposes that do not rely on external public trust.
