Designed with privacy and security at its core, protonURL ensures that shared data is accessible only once and is automatically deleted after first access or upon expiration. This makes it an ideal solution for securely transmitting passwords, confidential documents, or any sensitive content without leaving a trace. ## Features - Self-Destructing Links: Each link is designed to be accessed only once. Once the recipient views the content, it is automatically destroyed, preventing any further access and ensuring maximum confidentiality. - Automatic and Custom Expiry: Users can set expiration durations ranging from 1 hour to 1 year, or opt for the default 72 hours. If the link remains unaccessed within this period, it is automatically deleted from the server. - End-to-End Encryption: Content is encrypted using AES-256-CBC encryption, ensuring that data remains secure during transmission and storage. Attached files are encrypted similarly and stored outside web directories for added security. - Optional Custom Keys: Users can encrypt their content with their own secret keys, adding an extra layer of security. The recipient will need this key to decrypt and view the shared content. - No Data Retention: ProtonURL does not store shared data after it has been accessed or expired. The service guarantees that no copies are kept, and all shared content is permanently deleted, ensuring privacy and confidentiality. - Proof of Deletion: The platform offers cryptographically signed proofs that certify content has been permanently destroyed, providing verifiable evidence of data deletion. ## Use Cases 1. Individuals sharing sensitive information: A user can securely send a password or private message to a trusted contact, knowing that the link will self-destruct after first viewing, preventing any future leaks. 2. Professionals exchanging confidential documents: A lawyer or financial advisor can share sensitive files with clients via a temporary link, ensuring that the data is accessible only once and is automatically deleted afterward. 3. Teams collaborating securely: Teams working on confidential projects can use protonURL to share critical information or code snippets, reducing the risk of data leaks and ensuring compliance with privacy standards. ## Benefits - Enhanced Privacy: The self-destruct feature and automatic deletion policies guarantee that shared data is not stored longer than necessary, protecting user privacy. - High Security: End-to-end encryption and optional custom keys ensure that only intended recipients can access the content, even if intercepted during transmission. - Ease of Use: The platform provides a straightforward interface for creating secure links, attaching files, and setting expiration times, making secure sharing accessible to all users. - Verifiable Deletion: Proof of deletion features offer transparency and trust, allowing users to verify that their data has been permanently destroyed. ## Conclusion protonURL offers a robust, privacy-focused solution for securely sharing sensitive information through temporary, self-destructing links. Its combination of strong encryption, automatic deletion, and user-friendly features makes it an invaluable tool for individuals and professionals alike who prioritize confidentiality and data security.
