Intercept, inspect, manipulate HTTP/HTTPS traffic

npm install -g hin

npm update -g hin

First time run:

hin

will generate private key and Root CA certificate inside ~/.hin folder. Proxy will be listening in 8001 port by default. To specify custom port use --port option:

hin --port 4001

Next time you run Http Interceptor it will check for generated certificate and use it. In addition you can specify path to custom private key and Root CA certificate:

hin --cert <path_to_root_cartificate> --key <path_to_private_key>

You can re-generate private key and Root CA certificate by using --generate option:

hin --generate

For Http Interceptor to be able to intercept SSL traffic you need to add generated Root CA to Trusted Roots.

The following command will add generated certificate to your login keychain and mark as trusted:

security add-trusted-cert -d -r trustRoot -k ~/Library/Keychains/login.keychain ~/.hin/_ca.crt

sudo cp ~/.hin/_ca.crt /usr/local/share/ca-certificates/hin_ca.crt
sudo update-ca-certificates

sudo cp ~/.hin/_ca.crt /etc/pki/ca-trust/source/anchors/hin_ca.crt
sudo update-ca-trust

sudo cp ~/.hin/_ca.crt /etc/ca-certificates/trust-source/anchors/hin_ca.crt
sudo update-ca-trust

sudo cp ~/.hin/_ca.crt /usr/share/ca-certificates/hin_ca.crt
sudo update-ca-certificates

The following powershell commands will add generated certificate to current user's Trusted Root Certification Authorities list:

PS> Import-Module pki
PS> Import-Certificate -FilePath "${env:USERPROFILE}\.hin\_ca.crt" -CertStoreLocation Cert:\CurrentUser\Root

Firefox manages its own certificate authorities list. Open Preferences (about:preferences) View Certificates section and import generated Root CA certificate. You need to check 'This certificate can identify websites.' during import.

Chromium manages its own certificate authorities list. Open Certificate Settings (chrome://settings/certificates) Authorities section and import generated Root CA certificate. You need to check 'Trust this certificate for identifying websites' during import.
