Developers Guide

• You can call the PKCloud interface using a REST API, or use a thin java or .NET client


• Details of each of these are given below


• Code samples are available on github and a test service is available for you to try

Java Interface

• Take a look at the sample client on github


• This will get you started generating and verifying signatures using the online test service


• If you want to integrate the client into your own java application, use the following maven dependency:
<dependency> <groupId>com.krestfield.ezsign</groupId> <artifactId>ezsign-client</artifactId> <version>4.0.0</version> </dependency>
• For other builds (or to manually download the client jar), see here


• The Client Integration Guide is available here

.NET Interface

• Download the .NET client library from here


• Take a look at the sample client on github


• Or download the simple windows test tool from here

REST API

• Download the REST API specification here


• Or download the Postman files from here and try running the API in Postman

Test Service

• A test service is available which provides the following options:


• REST API listening on port 443 (https) at demoapi.krestfield.com. A valid API user account is required to authenticate to this API


• Krestfield thin client API listening on port 80 at demoapi.krestfield.com. Protected with an authCode

For both options you can email Krestfield Support to obtain valid credentials


• The following channels are available:


• P7_RSA_SIGN_CHANNEL
This channel produces a PKCS#7 formatted signature generated using RSA


• P7_ECDSA_SIGN_CHANNEL
This channel produces a PKCS#7 formatted signature generated using ECDSA


• RAW_RSA_SIGN_CHANNEL
This channel produces a RAW (PKCS#1) formatted signature generated using RSA


• RAW_ECDSA_SIGN_CHANNEL
This channel produces a RAW (PKCS#1) formatted signature generated using ECDSA


• AES_ENCRYPT_CHANNEL
This channel can be used with the encrypt and decrypt calls and holds keys with labels KEY1, KEY2 and KEY3
