Description: An End Entity Certificate is a type of digital certificate issued to an end user or specific device, allowing the use of public key cryptography. This certificate contains information that links the identity of the holder with a public key, which is used to encrypt and digitally sign data. End entity certificates are fundamental in Public Key Infrastructure (PKI), as they ensure the authenticity and integrity of communications in digital environments. Being issued by a Certificate Authority (CA), these certificates ensure that the identity of the user or device has been verified, allowing trust to be established in electronic transactions. Additionally, end entity certificates may include additional information, such as expiration date, signing algorithm used, and usage policies, making them versatile tools for managing digital identities across various applications, from secure email to authentication in networked systems.
