Caching in Mule 4: How It Works

Caching in Mule 4

Overview

Caching is the term for storing reusable responses in order to make subsequent requests faster. There are many different types of caching available, each of which has its own characteristics. Application caches and memory caches are both popular for their ability to speed up certain responses.

By storing relatively static data in the cache and serving it from the cache when requested, the application saves the time that would be required to generate the data from scratch every time. Caching can occur at different levels and places it in an application.

PGP Encryption in Mule 4: How it Works

Expert in the field (10/10 deserves a sugar cube)

Overview

The flow of information that runs through the average business every day is like a river. It’s massive and holds the potential for danger if you’re not careful. Scammers easily lift data from your payment systems if you let them and use it to steal your information. When working with clients, it's very common to receive and send sensitive information, such as server names, usernames, passwords, or even clients' internal information. Sharing this information via an email, text, files, or a 'chat' program is very insecure, unless you encrypt the information using a good encryption method.

Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting and decrypting texts, E-mails, files, directories, and whole disk partitions to increase the security of e-mail communications. It was created by Phil Zimmermann in 1991.
