Cherry Tree Florist takes its online security very seriously. This is why we use the the safest Australian 3rd Party Online payment gateway to take your payments.
See below for an extract from the Stripe website for security measures:
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.
Stripe forces HTTPS for all services, including our public website. 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 Chrome and Firefox.
For more about implementing SSL on your own website, read our SSL guide.
All card numbers are encrypted on disk 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.).
We rapidly investigate all reported security issues. If you believe you've discovered a bug in Stripe's security, please get in touch at firstname.lastname@example.org (optionally using our PGP key at the bottom of this page). We will respond as quickly as possible to your report. We request that you not publicly disclose the issue until it has been addressed by Stripe.
