Java Key Extractor

The tool performs static analysis of Java code and configuration to locate hard-coded API keys and secrets. It targets Java source files (.java, .kt), properties, YAML, JSON, and common build files like pom.xml and build.gradle. It does not execute the code; instead it scans textual content for patterns that resemble credentials. The result is a structured report that highlights potential exposures, enabling secure remediation before deployment to reduce risk and enable structured remediation.
Conceptually, the tool maintains a pattern library of credential formats (e.g., AWS_ keys, private keys, API tokens). It applies regex and heuristic checks to relevant file types, records location data (file path, line number, surrounding context), and deduplicates identical findings. Findings are categorized by risk and can be exported as JSON or CSV for integration into CI and ticketing workflows.
Audience and value: security engineers, developers, QA, and DevOps teams benefit from early detection, reduced blast radius, and faster remediation. Unique differentiators include customizable pattern sets, per-project scoping, incremental scans, and CI hooks. It also supports exporting redacted results to publish in security dashboards while protecting secrets from exposure.
Typical use cases include pre-commit checks in PR pipelines, nightly repo-wide scans, and security audits of Java-based applications. The tool complements runtime secret scanners by locating credentials committed in source or configuration, guiding developers to remove hard-coded keys and adopt secure storage practices.
