Secure Encrypted QR Code Generation | Electronic Authentication with App

Qryptal Secure QR code technology is uniquely designed to make any physical or electronic document tamper-proof and instantly verifiable by any third party in a unique server-less architecture.

The secure QR code solution easily plugs into existing document production systems. It generates a highly secure digital signature with embedded data that is placed on the document as a QR Code. Anyone can instantly verify the credibility of the information by scanning that code with an App on their smartphone.

This novel architecture provides many benefits:

  • Server-less: Qryptal QR code solutions are built on a server-less architecture that enables the solution to scale and makes it virtually maintenance-free. Since there are no servers, once the document is issued - no further infrastructure is required needed to keep it verifiable
  • Security: Secure QR code solution, is based on PKI, with a key size equivalent of 3072 bit, it is much more secure than typical internet banking
  • Off-line Verification: Since the Qryptal QR code is self-contained there is no need for any network connectivity to validate the information. Thus the verification can work anytime and anywhere including in secure air-gapped environments
  • Physical-digital: Works for electronic as well as printed documents. This blend of physical and digital world is where a secure Qryptal QR is generated digitally and can be then placed on both the physical as well as the electronic version of the document as required. Both the the printed copy and the electronic format of the original document carries the same level of security and can be verified easily.
  • Privacy: Qryptal helps safeguard and protect the privacy & confidentiality of the customer and institution in an uncomplicated logical manner

Secure Encrypted QR Code Generation | Electronic Authentication with App

The essential workflow for deploying Qryptal is to integrate with the Qryptal Generator API. The Qryptal Secure QR Code can be generated and seamlessly added to your documents to enable easy validation.

Sample Document with Qryptal Code

For validation, end-users can install the Document Validator App. You can try the following steps to install it on your mobile phone:

  • 1. On your mobile, visit and follow one of these 3 methods : (a) click on the Use Camera button to scan the code directly using the browser camera or (b) Upload Image/PDF file button to upload the image or PDF file containing the code or (c) Install the app
  • 2. After the app has been installed, scan the code below:

The organisation's private key digitally signs the secure QR code. The keys are generated initially as part of the setup. The mobile App and the web validation mechanism uses the organisation's public key to validate the digital signature. Further, the entire code is explicitly compressed to create the smallest possible QR Code size. Contact us to learn more about this.

  The Qryptal Generator offers a REST API which can be called from almost any programming language/system.
You can sign up for free to try the API.

Qryptal Secure QR Codes are of two types:

  • - Primary Data Codes (PDC): These are self- contained codes which encapsulate all the information within the code itself. The recommended capacity of these codes is about 2,000 characters – large enough for a textual bank account statement like the sample given above.
  • - Extended Data Codes (EDC): These codes can also contain attachments like images and PDF files. The attachments are encrypted and stored as BLOBS in object-store. The decryption key and their fingerprints are stored within the QR. This prevents any subsequent tampering of the codes.

Both the codes can be revoked or chained with a new code.
