Circles - Encrypted E2E VOIP + 2.68

Circles is an application that prioritizes user privacy. The app offers top-notch end-to-end security and encryption for voice and video calls, messages, classifieds, events, and location points.

Security standards compliance for voice and video VOIP includes NIST SP800-56 rev3 C(2e, 2s) and HKDF (RFC5869) standards. It utilizes AES128, HMAC256, ECDH128, ECDSA256 encryption protocols.

Contacts can be added via the sharing of a 'public key' over the internet and Bluetooth, ensuring secure connections.

Users can verify the access of members to their Circles through cryptographic means. Additionally, Circle owners have the ability to allocate cryptographic Vouchers to members.

Key features of Circles include customizable Circle settings such as member invitation controls and message-sharing permissions.

• When creating a Circle, you can specify who has the authority to add members and share content.

The app also includes functionality for badging and voucher distribution. Circles can be used to manage event access, service usage via vouchers, and establish privileges.

• Each Circle serves as a platform for monitoring event entries, service access using vouchers, and verifying Circle membership privileges.

With respect to cloud services, Circles seamlessly synchronizes data across devices linked to the same iCloud account using iCloud Keychain and iCloud Drive.

• You can initiate conversations on one device and seamlessly continue them on another device within the iCloud network.
• Thanks to end-to-end security measures, message data, images, classifieds, and GPS coordinates can be securely stored on servers rather than occupying device storage space.
