Java

Updated August 16, 2026

dev.kryptic:krypticdev fetches your project's secrets and exposes them as system properties (the JVM cannot modify its own process environment). Zero dependencies, Java 17+. Outside development it is a no-op, and it never throws.

Install

<dependency>
  <groupId>dev.kryptic</groupId>
  <artifactId>krypticdev</artifactId>
  <version>0.1.0</version>
</dependency>

Use

public static void main(String[] args) {
    Kryptic.inject();   // before the framework boots

    var dbUrl = System.getProperty("DATABASE_URL");
}

For frameworks that want a map instead of system properties, use Kryptic.fetch():

Map<String, String> secrets = Kryptic.fetch();

Behavior

• No-op when SPRING_PROFILES_ACTIVE/APP_ENV/ENVIRONMENT/ENV indicates production or staging, or when KRYPTIC_DISABLED=true.
• Finds kryptic.json by walking up from the working directory.
• Never overwrites system properties or environment variables that are already set.
• macOS/Linux via unix domain socket channels, Windows via named pipe.
