Unbreakable Encryption and Zero-Knowledge Architecture
At the core of SECURECRYPT security is its use of end-to-end encryption (E2EE) across all forms of communication—messages, calls, and file transfers. This means that your data is encrypted on your device before it is sent and remains encrypted until it reaches the intended recipient. Only the communicating users hold the decryption keys, ensuring that no one, including SecureCrypt, can access the content of your communications.
Our platform is built on a zero-knowledge architecture, meaning that we do not have access to user data, nor do we retain the capability to comply with external requests for access. As a result, SECURECRYPT does not respond to requests from law enforcement for user data or communications, as we do not have the technical capability to decrypt or retrieve such information. This commitment to non-disclosure is a cornerstone of our privacy philosophy.
Sophisticated Anti-Surveillance Features
In today’s world, where surveillance is becoming increasingly sophisticated, SECURECRYPT offers a range of advanced anti-surveillance tools designed to protect your identity, location, and privacy:
Systems IP Masking: Our platform employs advanced IP masking technology, dynamically altering your IP address during internet sessions. This ensures complete anonymity, preventing any form of tracking or surveillance by malicious entities.
Private Closed Network: If enabled, SECURECRYPT Private Closed Network feature offers an unparalleled level of privacy for your communications. By creating an exclusive, closed network, you ensure that only authorized members can access and communicate within your network. Even other SecureCrypt users cannot find or contact you, providing a completely isolated and secure environment.
Offshore Infrastructure: In an era where digital surveillance is increasingly pervasive, SECURECRYPT offshore infrastructure provides a crucial shield against government overreach and unauthorized data access. By strategically hosting our servers in privacy-friendly jurisdictions, SECURECRYPT ensures that user data remains outside the reach of intrusive surveillance laws and mass data collection programs. Unlike services subject to data retention mandates or backdoor access requirements, our secure servers are designed to operate beyond the influence of restrictive regulations.
This infrastructure not only guarantees end-to-end encryption and system-level IP masking but also provides a zero-knowledge framework, ensuring that even SECURECRYPT cannot access user data.
For journalists, activists, businesses handling sensitive communications, and individuals prioritizing absolute privacy, SECURECRYPT offshore infrastructure offers a safe haven for secure and uncompromised communication in a world where digital freedom is under constant threat.
Cutting-Edge Communication Features
SECURECRYPT goes beyond basic encryption to provide a suite of communication tools designed for maximum security:
Encrypted Chat, Calls, and Group Chats: Every communication—whether one-on-one or in a group—is fully encrypted, ensuring that your conversations remain private and secure. Even group chats maintain complete anonymity for all participants, with no exposure of user IDs.
Secure Voice Changer: Transform your voice in real-time during any voice or video recording, ensuring complete anonymity. This feature is particularly useful in sensitive situations where maintaining anonymity is crucial.
Remote Wipe: Remotely Wipe your device if is lost or stolen.
Ability to load our MDM onto a custom hardened OS.
Innovative Security Features for Extreme Situations
SecureCrpt is packed with features that are designed to enhance your security in every possible scenario:
Panic Wipe and Remote Wipe: In the event of an emergency, these features allow you to quickly erase all app data with a single action. The data is not just deleted but is physically overwritten with zeros, ensuring that it is completely unrecoverable.
Duress Password: This feature allows you to enter a secondary password that triggers a panic response, instantly wiping the app and securing your sensitive information without alerting any intruder. It’s an added layer of security for high-pressure situations.
Stealth Mode and Chat Masking: Stealth Mode hides the SECURECRYPT app from your home screen and recent apps list, concealing it behind a fully functional calculator. Chat Masking allows you to instantly replace any conversation with a random, innocuous one by simply double-tapping, ensuring that sensitive discussions remain hidden even during unexpected inspections.
Self-Destructing Messages: For additional privacy, messages can be set to delete themselves after a specified period from both the sender’s and recipient’s devices.
Infrastructure and System-Level Protections
SECURECRYPT commitment to security extends to its infrastructure and system-level protections:
Layered Relays and Network Obfuscation: SECURECRYPT routes all network traffic through multiple reverse proxy layers distributed across different jurisdictions so every visible node functions only as a relay and the true location of core infrastructure remains concealed. Relays pass encrypted payloads and do not retain persistent data so network scans or autonomous system analysis cannot reveal origin servers. If a single relay is compromised it only exposes the next hop in the chain, reducing blast radius and protecting the internal network. This layered relay architecture is central to our approach to operational security and resilient privacy.
Secure Boot and Kernel Hardening: Our devices undergo a secure boot process that ensures only a signed OS can be loaded, with each stage of the process verifying the next component. Kernel hardening further reduces the attack surface, making SECURECRYPT-powered devices more resilient against unknown vulnerabilities.
Full Disk Encryption and Enhanced Memory Protections: Encryption is turned on automatically on all SECURECRYPT devices and cannot be disabled. We also employ address space layout randomization (ASLR) to prevent memory exploitation, ensuring that even if an attacker gains access, they cannot predict the location of system components.
Root of Trust: Established during manufacturing, our Root of Trust provides hardware-based device authentication and secure boot, ensuring that every device remains tamper-proof and secure.
Downgrade Attack Prevention and Integrity Detection: SECURECRYPT prevents any attempts to load older OS versions that lack the latest security fixes. Integrity detection continuously monitors for unauthorized changes, ensuring that the device remains secure at all times.
Secure Global SIM
SECURECRYPT extends its security protocols to the cellular network with specialized SIM security features:
Secure Global SIMs: Our SIMs offer the highest level of privacy, including subscriber location protection, identity protection, and GSMA security. These features prevent unauthorized location tracking and identity disclosure at the SS7/network/cellular level.
OTA Encryption and Mutual Authentication: Over-the-air (OTA) messages are encrypted using 128-bit AES encryption keys, ensuring that configuration updates are secure. Mutual authentication between devices and the mobile core network further protects against cell site simulator (CSS) attacks.
SIMJacker Protection and Tamper-Proof SIMs: SECURECRYPT SIMs are protected against SIMJacker attacks by removing vulnerable applications and enhancing security monitoring. Our SIMs comply with GSMA and GlobalPlatform standards, ensuring they are tamper-resistant and secure.
SECURECRYPT employs our own secure cellular core (SPLMN) which acts as a private mobile provider. In simple terms, a Secure Public Land Mobile Network (SPLMN) is like a private, fortified mobile network that protects calls, messages, and data from unauthorized access. Unlike standard public cellular networks, which are vulnerable to interception, and vulnerabilities that affect traditional cellular (SS7) mobile networks, an SPLMN ensures secure, encrypted, and controlled communication.
SECURECRYPT Secure Public Land Mobile Network (SPLMN) offers a fortified mobile communication environment designed to safeguard users against a spectrum of cyber threats and unauthorized surveillance. By integrating advanced security measures, the SPLMN ensures that all data transmitted within the network remains confidential and protected from interception.
SECURECRYPT SPLMN is located offshore, in a privacy focused region for an added layer of privacy that you cannot get with free apps, other paid apps, or any other international telecom provider.
Encrypted Backups: Protecting What Matters Most
SECURECRYPT understands the importance of safeguarding essential data without compromising privacy. We offer Encrypted Backups that include only your contacts and vault, ensuring that these critical components are securely stored and recoverable in the event of data loss. Messages are deliberately excluded from backups to eliminate any risk of sensitive information being compromised.
Our backup process employs advanced encryption techniques, ensuring that data is encrypted on your device before being transmitted and stored. With only you holding the decryption keys, the security of your backed-up data is guaranteed, offering peace of mind that even in scenarios where backups are accessed, the content remains secure, private, and inaccessible to anyone but you.
This also makes changing devices painless and seamless if your device is lost or stolen.
Commitment to Non-Disclosure and Privacy
SECURECRYPT is unwavering in its commitment to protecting the privacy and security of its users. As part of this commitment, SECURECRYPT does not respond to requests from law enforcement for access to user data or communications. Our infrastructure and encryption protocols are specifically built to prevent any unauthorized access, including from government or law enforcement agencies.
Operating within privacy-friendly jurisdictions, our infrastructure is designed to ensure that user privacy is protected to the highest degree possible. SECURECRYPT does not store encryption keys or have any access to the content of communications that take place on our platform, making it technically impossible for us to comply with any such requests.
