Digidentity CA Portal

Rewrite of online digital certificate store

Client

Digidentity

Services

Ruby on Rails, Turbo, Stimulus, PKI

Digidentity is a Dutch digital identity company, headquartered in The Hague. It provides digital identity verification services for people and businesses to prove who they are online. Its core products include eHerkenning (the login method Dutch businesses use to access government and public-sector services), digital signing, and issueing digital certificates.

Tilted helped build the new digital certificate store, meeting tight deadlines and stringent requirements.

Strict industry requirements

As a trusted certificate authority Digidentity must meet strict industry requirements and undergo regular independent audits. Failing to meet those requirements or experiencing significant security or operational issues, browsers and operating systems may distrust its certificates.

The existing certificate store was outdated and did not meet the requirements for the new PKIoverheid certificates. As Digidentity wanted a totally different certificate purchase workflow, it was decided to rewrite the application from scratch.

Meeting tight deadlines

As Digidentity’s default technology stack, using Ruby on Rails for the new application was an easy choice.

By using Ruby on Rails with Turbo and Stimulus we were able to create an application that was both accessible and interactive. Using Rails for rendering HTML allowed us to get a working application running in no time. By setting priorities and focusing on the core requirements we were able to implement everything within the given deadlines.

The external auditors were impressed with our new solution and Digidentity got their stamp of approval.

Browser based CSR generation

Purchasing a digital certificate is a challenging process. It requires a customer to have deep technical skills (using Unix command line with hard to use tools like OpenSSL).

Due to recent cryptographic support in Javascript, we were able to create a much more user friendly certificate request experience. Making this the worlds’ first browser based certificate purchase process. The CSR (Certificate Signing Request) was created in the browser of the customer, no longer requiring the customer to create a CSR on the command line.

DiverData

From proof of concept to turn key production ready SaaS

Client

DiverData

Services

Ruby on Rails, Design, Project management

DiverData is the digital hub for professional divers, diving companies and accreditation bodies. It helps divers log their dives and store their digital documents. Diving companies manage their equipment and its preventative maintenance, and get insights in their divers skill development.

Tilted designed and built the original proof of concept, and now manages the production environment as well as build new features.

Digitalization for the commercial diving industry

The commercial diving industry is famous for being very conservative when it comes to the digital age. Logbooks, equipment maintenance, certificates, everything is analog. In the digital age, we can do better, and so we did.

Together with DiverData we built a proof of concept digital logbook using Ruby on Rails. Based on industry feedback we expanded the platform with functionality for diving companies, including a Preventative Maintenance System (PMS).

Full Application Lifecycle Management

Building a proof of concept is one thing. Managing and maintaining a platform used by thousands of divers and diving companies is another. Titled now manages the production environment as well as build new features.

Docfield

Improve CI, testsuite and SAML endpoints

Client

Docfield

Services

Ruby on Rails, CI performance, SAML

Docfield is an Amsterdam-based contract and document management platform. It helps organizations manage proposals, contracts, policy documents, and HR records. It does this by offering an innovative solution for document workflow, from drafting to signing.

Tilted helped Docfield improve their Continuous Integration (CI) pipeline and codebase, as well as implement new features.

Improving CI / Testsuite performance

Docfield had a great CI setup, but tests were slow. A slow CI slows down development, making it harder and more costly to detect problems in code changes. This impacts delivery of new features to customers. Tilted was able to drastically improve the speed of Docfield’s testsuite by getting rid of obsolete code and tests.

For local development testsuite performance is just as important. Tilted improved running the testsuite locally by parallelizing the testsuite. Running a test suite in eight parallel processes improves the performance almost by the same factor.

Refactor SAML authentication

Security Assertion Markup Language (SAML) is an open standard for exchanging authentication and authorization data. SAML is commonly used for single sign-on (SSO) for authentication into web applications.

Many of Docfields’ customers use SAML to log in. As we had prior experience implementing SAML, we were able to improve the login process and make it more robust and easier to connect new customers.

Mobiel.nl

Re-implement postpaid functionality

Client

Mobiel.nl

Services

Ruby on Rails, domain modeling, performance

Mobiel.nl is an independent Dutch online marketplace for comparing and buying mobile phones and plans. Phone plans can be combined with cable television and broadband internet plans.

Tilted built the new backend for managing products, plans and discounts.

Redesign of core business logic

Selling mobile phone plans with different parameters, from multiple providers, is harder than you might think. Combine this with plans for cable television and broadband internet plans and things get even more complicated. Add discounts for certain combinations and things get difficult to manage.

Many have tried and failed, including some big names.

Together with business people we were able to create a new and more flexible postpaid solution, such that Mobiel.nl could improve their competitive advantage over their competitors.
