Certificate Authority (CA)

4 minute read
Certificate Authority (CA) is a crucial component of the public key infrastructure (PKI), playing a central role in ensuring the security and authenticity of digital communications. A CA is a trusted entity that issues digital certificates, which are electronic documents that bind a public key to a specific individual or organization.
Understanding Certificate Authorities
CAs verify the identity of the entities requesting certificates, ensuring that the public key is genuinely associated with the entity it claims to represent. This process involves rigorous checks and validation, including verifying the applicant's legal existence, physical address, and authorized representatives.
Once a CA has verified the applicant's identity, it issues a digital certificate. The certificate contains identifying information about the entity, such as its name, email address, and organization, along with the public key and the period of validity.
