Product Decisions This Supports

Enables secure cryptography in environments where native libsodium is unavailable (e.g., shared hosting, legacy servers), eliminating environment-specific code paths.
Provides a consistent, audited API for encryption, authentication, and key management across all PHP versions, reducing security risks from custom implementations.
Supports a strategic build-vs-buy decision by leveraging a battle-tested, production-ready solution instead of building in-house crypto (which is error-prone and high-risk).
Facilitates roadmap planning for future upgrades to native ext/sodium with zero code changes, ensuring long-term maintainability and compliance.

When to Consider This Package

Adopt when your infrastructure lacks the ability to install native PHP extensions (e.g., restricted hosting, multi-tenant platforms) or when cross-environment consistency is critical (e.g., dev/staging/production parity).
When security compliance requires standardized, vetted cryptographic primitives without reinventing the wheel.
Avoid when all target environments can reliably install native libsodium (for optimal performance), or when your project already uses a different crypto library with no migration path (e.g., OpenSSL-only codebases).

Executives: "This package ensures our application uses industry-standard, audited cryptography without server modifications or infrastructure costs. It eliminates security risks from inconsistent crypto implementations across environments, directly protecting user data and meeting compliance requirements with minimal effort—no custom code, no new dependencies, just proven security out of the box."
Engineering: "It’s a drop-in polyfill that mirrors the native sodium_* API, so you can write crypto code once and run it everywhere. No environment-specific logic, no refactoring for production—same code works on shared hosting, cloud servers, or local dev. Switch to native ext/sodium later with zero code changes, backed by a 900+ star, security-reviewed library trusted by production systems."
