CA Root Certificate Installation

The CA Root Certificate Installation process is a critical requirement when configuring network analysis tools like Fiddler Classic to intercept and decrypt HTTPS traffic.^[600-developer__tools__mobile__Fiddler-Classic.md]

Context in Network Debugging

Tools such as Fiddler Classic act as a proxy, sitting between the client (e.g., a mobile device) and the server.^[600-developer__tools__mobile__Fiddler-Classic.md] To successfully analyze secure HTTP (HTTPS) traffic, the tool must be able to decrypt the data.^[600-developer__tools__mobile__Fiddler-Classic.md]

The Installation Process

To enable this decryption, the device under inspection must trust the proxy.^[600-developer__tools__mobile__Fiddler-Classic.md] This is achieved by installing the tool's specific Certificate Authority (CA) root certificate onto the client device.^[600-developer__tools__mobile__Fiddler-Classic.md]

Once the CA root certificate is installed and trusted, the debugging tool can intercept the connection and present its own certificate to the client, which the client will accept as valid.^[600-developer__tools__mobile__Fiddler-Classic.md]
