Q: What SDKs and programming languages does Cryptolens support?

Cryptolens provides official SDKs for .NET/C#, Python, Java, C++, and Node.js, plus a REST API that works with any language. The SDK handles licence key validation, feature checks, and usage reporting with a few lines of code. For platforms without an official SDK, our development team builds lightweight API wrappers that integrate Cryptolens into any application architecture.

We can help you automate your business with Cryptolens and hundreds of other systems to improve efficiency and productivity. Get in touch if you’d like to discuss implementing Cryptolens.

About Cryptolens

Cryptolens is a software licensing platform that lets developers add licence key validation, feature gating, usage tracking, and subscription management to their applications. It provides APIs and SDKs for .NET, Python, Java, C++, and other languages, so you can enforce licensing rules directly in your software without building a custom system.

The problem Cryptolens solves is licence enforcement. Software companies that sell desktop applications, plugins, APIs, or on-premises tools need a way to verify that users have valid licences, restrict access to paid features, and track usage for billing. Building this from scratch is time-consuming and error-prone. Cryptolens handles key generation, validation, activation limits, expiry dates, and feature flags through a managed API.

At Osher, we integrate Cryptolens into client applications and connect it to business systems as part of our system integration and custom development work. A typical project connects Cryptolens to a payment system (Stripe, Paddle) so that licence keys are generated automatically on purchase, activated when the user installs the software, and deactivated when a subscription lapses. We also build dashboards that pull usage analytics from Cryptolens for product and sales teams.

Cryptolens is built for software vendors, ISVs, and development teams that distribute commercial software and need reliable licence management without building and maintaining their own licensing infrastructure.

Cryptolens FAQs

Frequently Asked Questions

Common questions about how Cryptolens consultants can help with integration and implementation

What licensing models does Cryptolens support?

Cryptolens supports perpetual licences (one-time purchase, never expires), time-limited licences (expires after a set period), subscription licences (tied to recurring payments), feature-based licences (different tiers unlock different features), floating licences (limited concurrent users), and usage-based licences (metered by API calls or other metrics). You can combine these models, for example offering a subscription licence with feature gating and usage limits.

How does Cryptolens integrate with payment platforms like Stripe?

Cryptolens can be connected to Stripe, Paddle, and other payment platforms through webhooks and API calls. When a customer completes a purchase, a webhook triggers Cryptolens to generate and deliver a licence key. When a subscription is cancelled or a payment fails, the licence is automatically deactivated. Our integration team builds these connections using n8n so the entire purchase-to-activation flow runs without manual intervention.

Does Cryptolens work offline or only with internet connectivity?

Cryptolens supports offline activation. Your application can validate a licence key against Cryptolens servers during initial activation, then cache the licence locally for offline use. You configure how long the cached licence remains valid before the application needs to check in again. This is important for desktop software and on-premises tools that may not have constant internet access.

How does Cryptolens prevent licence key piracy?

Cryptolens uses RSA-signed licence keys that cannot be forged. Each key is validated against Cryptolens servers (or a cached, signed response for offline use), and you can set machine-locking to tie a licence to specific hardware. Activation limits prevent a single key from being shared across more machines than permitted. While no system stops all piracy, these measures make casual sharing and key forgery impractical.

Can we track how customers use our licensed software?

Yes. Cryptolens collects usage data (feature access, session counts, API call volumes) that you define through its analytics endpoints. This data feeds into dashboards for product and sales teams, showing which features are most used, which customers are approaching usage limits, and which accounts might be candidates for upselling. We build custom reporting on top of this data for clients who need specific analytics views.

How it works

We work hand-in-hand with you to implement Cryptolens

As Cryptolens consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate Cryptolens with integrate and automate 800+ tools.

Step 1

Process Audit

We review your current software distribution and licensing approach: how you generate and deliver licence keys, what licensing models you offer, how you handle activations and renewals, and where manual processes create friction. We assess your payment integration, piracy concerns, and reporting requirements to define the scope of the Cryptolens implementation.

Step 2

Identify Automation Opportunities

We map out which licensing operations can be automated: key generation on purchase, activation on install, feature gating based on licence tier, deactivation on subscription cancellation, and usage reporting for billing. We identify integration points with your payment platform, CRM, and support systems that can eliminate manual licence management tasks.

Step 3

Design Workflows

We design the licensing architecture: key structure and feature flags, activation and deactivation rules, offline validation parameters, and integration flows between Cryptolens, your payment platform, and your application. We plan the API integration points in your software and design the usage analytics pipeline for product and sales reporting.

Step 4

Implementation

We integrate the Cryptolens SDK into your application code, configure licence products and feature flags in the Cryptolens dashboard, build the payment webhook integrations using n8n, and set up usage analytics collection. We test the full lifecycle: purchase, key delivery, activation, feature access, renewal, and deactivation.

Step 5

Quality Assurance Review

We test every licensing scenario: new activations, machine transfers, offline validation, expiry handling, feature gating at each tier, and payment failure deactivation. We verify that licence keys cannot be reused beyond activation limits and that usage data reports accurately. We confirm that the payment-to-activation pipeline handles edge cases like refunds and failed webhooks.

Step 6

Support and Maintenance

We monitor the licensing pipeline for issues, update integrations when your payment platform or application architecture changes, and help you add new licensing tiers or features. We provide reporting on licence usage patterns and assist with troubleshooting customer activation issues as they arise.
