Package com.apicatalog.jcs

Provides an implementation of the RFC 8785 JSON Canonicalization Scheme (JCS) in Java.

The JCS specification defines a deterministic way to serialize JSON so that the same JSON data model always produces the same byte sequence. This ensures stable and repeatable representations of JSON values, which is critical for use cases such as digital signatures, hashing, and integrity verification.

The Jcs class offers methods for:

• Canonicalization – converting JSON values into their canonical string form using Jcs.canonize(javax.json.JsonValue) and related methods.
• Equality comparison – determining whether two JSON values are canonically equal using Jcs.equals(javax.json.JsonValue, javax.json.JsonValue).

This package relies on Jakarta JSON Processing (JSON-P) for parsing and representing JSON data.
