Action Summary

The Hash String GitHub Action generates a deterministic, 64-character HMAC-SHA256 hash of a given string using a secret salt. It is designed to anonymize sensitive data, ensure data integrity, or create reproducible identifiers within CI/CD pipelines. This action is cryptographically secure, requires no external runtime dependencies, and ensures that identical inputs yield consistent outputs while maintaining security through a salted hashing mechanism.
