Hasper internal CA

Internal Hasper hosts use certificates signed by HasperInternalCA. Install this certificate once on each device, and browsers and tools will trust those hosts without warnings.

Before trusting it, check the SHA-256 fingerprint shown by your system matches:
46:75:7E:86:FA:15:7D:BE:78:79:BE:3D:C8:2E:FC:EA:B0:57:EF:34:48:DE:82:95:0B:BF:68:EF:8F:D9:1F:F0
Subject O=Hasper, CN=HasperInternalCA, valid until 3 November 2036.

macOS

Double-click the file, add it to the System keychain, then open it in Keychain Access and set When using this certificate to Always Trust. Or in Terminal:

sudo security add-trusted-cert -d -r trustRoot \
  -k /Library/Keychains/System.keychain \
  ~/Downloads/hasper-internal-ca.crt

Windows

Double-click the file, choose Install Certificate, Local Machine, and place it in Trusted Root Certification Authorities. Or in an administrator PowerShell:

certutil -addstore -f Root $env:USERPROFILE\Downloads\hasper-internal-ca.crt

Linux

Debian and Ubuntu:

sudo cp hasper-internal-ca.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates

Fedora, RHEL and Arch:

sudo trust anchor --store hasper-internal-ca.crt

iPhone and iPad

Open this page in Safari and download the file, then go to Settings, General, VPN & Device Management and install the profile. Finally enable it under Settings, General, About, Certificate Trust Settings.

Android

Download the file, then go to Settings, Security, More security settings, Encryption & credentials, Install a certificate, CA certificate. Menu names vary by vendor.

Firefox

Firefox keeps its own list. Either set security.enterprise_roots.enabled to true in about:config so it uses the system store, or import the file under Settings, Privacy & Security, Certificates, View Certificates, Authorities, and tick Trust this CA to identify websites.

Command-line tools

Most tools follow the system store once it is installed. For one-off use: curl --cacert hasper-internal-ca.crt https://..., or set SSL_CERT_FILE, NODE_EXTRA_CA_CERTS or REQUESTS_CA_BUNDLE to the file.
