Cyber Cure

Ordinary protection has proven to be unsuitable, so we had to think outside the box, hence you got cryptoBox.


cryptoBox uses the highest levels of privacy and security and is a zero-knowledge provider. This means only YOU have the ability to access your information.


cryptoBox’s software is constantly improved and updated to provide our customers with the latest in technology and protection. This page provides an overview of cryptoBox’s security architecture, encryption methodologies and hosting environment as of the current published version. An overview into the technical details involving our encryption and security methods are described in this document.


Our Privacy Policy and Terms of Use are available on our website via the following links:

cryptoBox’s Best-In-Class Security

Private Master Password

ONLY the user has knowledge of and access to their Master Password and key that is used to encrypt and decrypt their information.

Strongest Encryption

cryptoBox protects your information with AES 256-bit encryption and PBKDF2, widely accepted as the strongest encryption available.

Multi-Users Uncompromised

cryptoBox offers multi-user architecture meaning you can create multiple account on the same device. Each user’s database, files, and configs are encrypted using completely separate keys from another user on same device. You can create multiple account with no security compromise to your other accounts!

AES256 Deep-Level Encryption

User data is encrypted and decrypted at the device level not on cryptoBox servers or in the cloud.

Secure/Reliable Stealthy Platform

cryptoBox utilizes Amazon AWS to host and operate the cryptoBox Stealthy Platform and architecture providing customers with the fastest and safest cloud storage. We manage your account access centrally, but even if internet is not available you can still login and browse all your contents securely!

Security Balanced with Performance

You can import a few GB large video. Even though your video is encrypted using incredibly strong AES256 encryption and stored using the best Defense-in-depth security practices, you can play it back within split second!

Data Protection

cryptoBox is a zero-knowledge security provider. The cryptoBox user is the only person that has full control over the encryption and decryption of their data. With cryptoBox, encryption occurs at the user’s device level throughout the entire transport process of the user’s app to cryptoBox’s Cloud Security Vault. The encryption key that is needed to decrypt the data always resides with the cryptoBox user. cryptoBox cannot decrypt the user’s stored data.


cryptoBox does not have access to a customer’s master password nor does cryptoBox have access to the records stored within the cryptoBox vault. cryptoBox cannot remotely access a customer’s device nor can it decrypt the customer’s vault. The only information that cryptoBox Security has access to is a user’s email address, device type and subscription plan details.


Information that is stored and accessed in cryptoBox is only accessible by the customer because it is instantly encrypted and decrypted on-the-fly on the device that is being used – even when using the cryptoBox Desktop App. The method of encryption that cryptoBox uses is a well-known, trusted algorithm called AES (Advanced Encryption Standard) with a 256-bit key length. Per the Committee on National Security Systems publication CNSSP-15, AES with 256-bit key-length is sufficiently secure to encrypt classified data up to TOP SECRET classification for the U.S. Government.


The cipher keys used to encrypt and decrypt customer records are not stored or transmitted to cloud.


Strong Master Password


It is highly recommended that customers choose a strong Master Password for their cryptoBox account. This Master Password should not be used anywhere outside of cryptoBox. Users should never share their Master Password with anyone.

Client Encryption

Data is encrypted and decrypted on the user’s device, not on the Cloud Security Vault. We call this “Client Encryption” because the client (e.g. iPhone, iPad) is doing all of the encryption work. The Cloud Security Vault stores a raw binary which is essentially useless to an intruder. Even if the data is captured when it’s transmitted between the client device and Cloud Security Vault, it cannot be decrypted or utilized to attack or compromise the user’s private data.


Breaking or hacking a symmetric 256-bit key would require 2128 times the computing power of a 128-bit key. In theory, this would take a device that would require 3×1051 years to exhaust the 256-bit key space.

Key Generation


cryptoBox uses PBKDF2 with HMAC-SHA256 to convert the user’s Master Password to a 256-bit encryption key with a minimum of 1,000 rounds.


Key Storage


All secret keys that must be stored (such as each user’s RSA private key and the Data Key), are all encrypted prior to storage or transmission. The user’s Master Password is required to decrypt any keys. Since cryptoBox’s Cloud Security Vault does NOT have access to the user’s Master Password, we cannot decrypt any of your keys or data.


cryptoBox’s Cloud Security Safe


The Cloud Security Safe refers to cryptoBox’s proprietary software and network architecture that is physically hosted within Amazon Web Services (AWS) infrastructure.

When the user synchronizes their cryptoBox  with other devices on their account, the encrypted binary data is sent over an encrypted SSL tunnel and stored in cryptoBox’s Cloud Security Safe in encrypted format.

Network Architecture

cryptoBox utilizes Amazon AWS to host and operate the cryptoBox solution and architecture. Utilizing Amazon AWS allows cryptoBox to seamlessly scale resources on-demand and provide customers with the fastest and safest cloud storage environment. cryptoBox operates both multi-zone and multi-region environments to maximize uptime and provide the fastest response time to customers.

Server Authentication


To prevent unauthorized vault access, cryptoBox’s Cloud Security Vault must authenticate each user when transmitting data. Authentication is performed by comparing a PBKDF2-generated hash of the Master Password. The user’s device uses PBKDF2 to generate the hash from the Master Password and the server compares the hash to a stored hash.



By using the PBKDF2 hash instead of the Master Password itself, the Cloud Security Vault authenticates the user without requiring the Master Password. PBKDF2 is also used for generating encryption data keys, but the authentication hash is not used for data encryption.

Transport Layer Encryption


cryptoBox supports 256-bit and 128-bit SSL to encrypt all data transport between the client application and KSI’s cloud-based storage. This is the same level of encryption trusted by millions of individuals and businesses everyday for web transactions requiring security, such as online banking, online shopping, trading stocks, accessing medical information and filing tax returns.


iOS Keychain and Touch ID®


Touch ID on iOS devices allows you to access your cryptoBox vault on your iOS device using your fingerprint. To provide this convenient feature, an unintelligible version of your Master Password is stored in the iOS Keychain. The iOS Keychain item created for this functionality is not designated to synchronize to the iCloud Keychain and thus will not leave your iOS mobile device.


It is highly recommended that you use a complex Master Password in order to provide maximum security for your encrypted cryptoBox Vault. Using Touch ID makes it more convenient to use a complex Master Password on your iOS mobile device.
The iOS Keychain is used by iOS and apps to securely store credentials. iOS apps use the iOS Keychain to store a variety of sensitive information, including website passwords, keys, credit card numbers and Apple Pay™ information. cryptoBox does not use the iOS Keychain to store your cryptoBox records – all cryptoBox records are protected with 256-bit AES encryption and are securely stored in the cryptoBox Stealthy Platform. The iOS Keychain is also encrypted with 256-bit AES encryption using the device’s passcode. Even if the device is lost or stolen or an attacker obtains physical access to the mobile device, they will be unable to access any stored cryptoBox information. The iOS Keychain cannot be decrypted without the passcode and the cryptoBox Vault cannot be decrypted without the user’s cryptoBox Master Password.

Phishing or Spoofed Emails


If you receive an email purporting to be sent from cryptoBox and you are unsure if it is legitimate, it may be a “phishing email” where the sender’s email address is forged or “spoofed”. In that case, an e-mail may contain links to a website that looks like cryptoBox but is not our site. The website may ask you for your cryptoBox Security master password or try to install unwanted software on your computer in an attempt to steal your personal information or access your computer. Other e-mails contain links that may redirect you to other potentially dangerous web sites. The message may also include attachments, which typically contain unwanted software called “malware.” If you are unsure about an email received in your inbox, you should delete it without clicking any links or opening any attachments.


If you wish to report an e-mail purporting to be from cryptoBox that you believe is a forgery or you have other security concerns involving other matters with cryptoBox, please contact us.
