Key lengths can be variable, but in general one should use a key length of 8 characters or more, or some key that can be at least 128 bits in length, or greater. Depending on the PKI technique used the key could vary anywhere from 128 bits to 2048 or more.
PKI is a set of procedures in order to establish a secure information. The six components are: Revocation, Certificate Authority, Certificate Publishing, Registration Authority, PKI aware application, Certificate Management System.
A critical concept common to all PKIs is the use of digital certificates issued by a trusted entity, known as a Certificate Authority (CA), to validate the identities of users and devices. These digital certificates contain public key information and are used to establish secure communications through encryption and digital signatures. Trust in the PKI is based on a hierarchical system where higher-level CAs vouch for the identities of lower-level CAs, creating a chain of trust.

system for encrpting sensitive information
One can receive a PKI certificate, or a public-key infrastructure certificate, is by digitally signing and publishing the public key bound to a given user.
A Public Key Infrastructure (PKI) itself does not perform encryption; rather, it provides the framework for managing digital certificates and keys that facilitate encryption. PKI enables secure communication by allowing users to encrypt data using the recipient's public key and ensures the integrity and authenticity of the data through digital signatures. The actual encryption and decryption processes are performed by the cryptographic algorithms that utilize the keys managed by the PKI.

It stands for Public Key Infrastructure. It has to do with security and data encryption.
