Payneteasy Key Pair Factory: Generate API Key Pairs in a Few Clicks

The hidden hurdle in every integration

Connecting to a payment gateway is rarely blocked by business logic. More often, it's blocked by the very first technical step: request authentication. To call the Payneteasy API securely, every request must be signed — and that means producing a cryptographic key pair and a correctly built OAuth signature.

In practice this involves generating an RSA key pair (often via OpenSSL), converting it between PKCS#8 and PKCS#1 containers, assembling a signature base string, percent-encoding it correctly, signing it with RSA-SHA256 or HMAC-SHA1, and packing everything into the Authorization header.

The full manual key generation flow is described in the Payneteasy API documentation.

One wrong character and the request is rejected. For a team without a cryptography specialist, this single step can turn a one-day integration into a one-week support thread.

What the app does

The Payneteasy Key Pair Factory removes that step entirely. It produces the key pair a merchant needs to authenticate with the platform — the keys required to connect to the Payout API and to initiate payouts through the virtual terminal in the personal cabinet.

Instead of installing OpenSSL, memorizing command flags and matching key formats by hand, the merchant gets the right keys in the right format, ready to use, in a few clicks. The private key stays with the merchant; the public key is what Payneteasy uses to verify each signed request.

The app is available as a public GitHub repository and can be downloaded from there.

Why it matters

Faster onboarding, fewer integration mistakes, and fewer support requests. By removing the hardest manual step, the app helps merchants complete their connection to the system sooner and with less back-and-forth during onboarding.

Flexibility without the friction

Payneteasy has always stood for depth: granular configuration, multiple authentication methods, and the flexibility that demanding payment businesses require. Historically, that depth came at a cost — complexity was the entry ticket.

Now that is changing. By investing in better tooling, we are keeping every bit of the flexibility while stripping away the friction that used to surround it. The Payneteasy Key Pair Factory is one concrete example: a hard, expert-only task turned into a simple, self-service action, without a massive engineering project behind it. Power and simplicity, finally on the same side.
