Encrypted by default

How the encryption works

Chobble Tickets encrypts names, emails, phone numbers, addresses, payment identifiers, ticket tokens, special instructions, and free-text custom question answers before saving them. Reading these fields requires a keyed administration session.

The encryption keys themselves are also encrypted. Each keyed user has a protected copy of the site's data key. An administration session unwraps that key after login and Chobble Tickets forgets it when the session ends.

A database dump on its own cannot reveal these protected fields. Access requires the additional key material held by a keyed administration session.

Three layers

Chobble Tickets stores data in three layers:

• Personal data (names, emails, phone numbers, addresses, free-text answers) is encrypted with a per-record AES-256-GCM key. RSA-OAEP wraps that key with the site owner's public key. The matching private key is encrypted and only a keyed admin session can use it.
• Listing and site details (names, descriptions, locations, images, site text, email settings, and payment-provider secrets) are encrypted at rest with the server's encryption key.
• Booking and operational metadata (relationships, dates, quantities, selected choice identifiers, income, availability, and capacity) is stored as plain values because the application has to total and compare it. This excludes direct contact fields, but selected identifiers can reveal information if someone also knows the corresponding form choices.

The exact algorithms (RSA-OAEP, AES-256-GCM, and PBKDF2 with 600,000 iterations) follow current OWASP, NIST, and IETF recommendations. The references and source code are listed at the bottom of this page for anyone who wants to audit the implementation.

Other security measures

Chobble Tickets also protects you from common web attacks.

• Cross-site request forgery protection. Each form contains a hidden token of 256 random bits, signed so it cannot be forged. The token stops other sites from tricking your browser into making changes on your behalf.
• Login rate limiting. Five failed attempts from the same IP address trigger a 15-minute lockout.
• Constant-time password checks. Chobble Tickets compares passwords in a way that takes the same amount of time whether they match or not, so an attacker cannot tell from the timing whether they got close.
• Content-type validation. Chobble Tickets checks the content type of every form submission, so an attacker cannot smuggle requests through endpoints that expect form data.
• Short admin sessions. Login sessions last for 24 hours. After that, Chobble Tickets signs you out and forgets your keys. The session cookie is HttpOnly, Secure, and SameSite=Strict, so other websites and scripts cannot read or send it.

Keyed accounts and recovery

Protected attendee fields are readable while a keyed administrator is signed in. The server unlocks the user's wrapped data key at the start of each session and discards it when the session ends.

Chobble staff do not receive the passwords for organiser-created accounts as part of managed hosting. Owners, managers, and logistics agents have their own credentials and key material. Content-only editors receive no attendee data key and cannot decrypt bookings.

When you invite a team member, they set their own password at a self-activation link. The invite is single-use, and the keys are re-wrapped under the new password as part of joining. The person who sent the invite never sees the new password.

An owner can choose to enable a recovery owner account when the host has configured a valid recovery email address and email delivery works. Chobble Tickets creates separate random credentials, wraps the same site data key for that account, and emails the credentials to the host-configured recovery address. Whoever controls those credentials can decrypt protected attendee fields and invite a replacement owner.

Organisers need to retain at least one keyed account or the enabled recovery credentials. Losing one person's password does not cause data loss while another keyed account remains available.

Algorithms in detail

For anyone who wants to verify the technical claims:

• Personal data (names, emails, phone numbers, addresses, payment identifiers, ticket tokens, and free-text answers): hybrid encryption using RSA-OAEP to wrap a per-record AES-256-GCM data key. Decryption requires the private key from the admin session.
• Encrypted site data (listing text and location fields, site copy, payment-provider secrets, email settings, and wallet credentials): AES-256-GCM with the server's encryption key.
• Password hashing and key derivation: PBKDF2-SHA256 with 600,000 iterations.
