Store description excerpt
CoCrypt is a high-security application that ensures your files are locked and can only be decrypted when all trusted participants provide physical confirmation through NFC and biometric authentication. How It Works Participant Registration: Each participant generates a key pair on their own device and shares their public key with the file owner exclusively via NFC—no internet or servers required. Owner-Side Locking: The file owner encrypts any file, and the encryption key is split into fragments corresponding to the number of participants, resulting in a single .ccr (veya tercih ettiğiniz uzantı) file ready for sharing. Collective Unlocking: To unlock a file, every participant must physically tap their phone to an NFC tag and authenticate via fingerprint or face recognition. The file cannot be decrypted unless everyone provides their consent. Key Features N-of-N Multi-Party Approval: The encryption key is distributed among participants. If even a single fragment is missing, decrypting the file becomes mathematically impossible. NFC Key Exchange: All key sharing is performed through physical proximity (NFC), eliminating the need for internet or cloud servers. Biometric Authentication: Participants must verify their identity using biometrics to release their specific key fragment. Challenge-Response Protocol: To prevent replay attacks, a custom time-stamped verification protocol is used for every unlocking session. Zero-Cloud & Zero-Account: CoCrypt has no backend server, requires no account creation, and stores your private keys directly in your device’s secure hardware. Compatible with All File Formats: Securely place documents, photos, or videos into a secure container and share them through any channel. Ideal For: Enterprises: Require the approval of all board members to access critical corporate files. Families: Encrypt sensitive documents like inheritance plans so they can only be opened when the whole family is physically together. Teams: Store shared secrets securely, ensuring no single individual has full authority. Journalists: Protect sensitive sources by tying access to the authorization of multiple colleagues. Offline Environments: Use seamlessly in air-gapped or internet-free environments thanks to NFC technology.
