Secure SSL Card Payments

We use Stripe to process all card payments, here is a little bit of background on stripe security:

Stripe has been audited by a PCI-certified auditor and is certified to PCI Service Provider Level 1. This is the most stringent level of certification available in the payments industry. To accomplish this, we make use of best-in-class security tools and practices to maintain a high level of security at Stripe.

HTTPS and HSTS for secure connections

Stripe forces HTTPS for all services using TLS (SSL), including our public website and the Dashboard.

  • Stripe.js is served only over TLS
  • Stripe’s official libraries connect to Stripe’s servers over TLS and verify TLS certificates on each connection

We regularly audit the details of our implementation: the certificates we serve, the certificate authorities we use, and the ciphers we support. We use HSTS to ensure browsers interact with Stripe only over HTTPS. Stripe is also on the HSTS preloaded lists for both Google Chrome and Mozilla Firefox.

Encryption of sensitive data and communication

All card numbers are encrypted at rest with AES-256. Decryption keys are stored on separate machines. None of Stripe’s internal servers and daemons are able to obtain plaintext card numbers; instead, they can just request that cards be sent to a service provider on a static whitelist. Stripe’s infrastructure for storing, decrypting, and transmitting card numbers runs in separate hosting infrastructure, and doesn’t share any credentials with Stripe’s primary services (API, website, etc.).

PGP

Stripe has two PGP keys to encrypt your communications with Stripe, or verify signed messages you receive from Stripe. Which key you make use of is dependent on the information needing to be transmitted:

If you’re unfamiliar with PGP, check out GPG, and start by importing a public key.
