Decompresso Laravel Package

Product Decisions This Supports

• Secure file ingestion and partner exchange: The 1.1.0 release adds symmetric GPG decryption, so the package can support both public-key and passphrase-based GPG workflows inside a Laravel application. This is directly useful for decrypting vendor, payroll, banking, claims, EDI, or legacy batch files before processing.
• Build vs. buy for crypto plumbing: Use this package when the product need is narrow—GPG encrypt/decrypt within Laravel—rather than building shell-script wrappers or bespoke OpenPGP handling. It can reduce integration time for partner onboarding and internal secure-file workflows.
• Roadmap and feature prioritization: Symmetric decryption unblocks use cases where partners encrypt with a shared passphrase rather than a public key. PM should treat this as an enabler for specific integrations, not as a complete encryption platform.
• Compliance and security feature scoping: The release expands functional coverage but does not replace key management, secret rotation, HSM/KMS, audit trails, or certificate lifecycle management. Product decisions should pair adoption with secrets management and logging requirements.
• Use cases to evaluate: Inbound PII/financial file processing, vendor data drops, legacy PGP workflows, test-fixture decryption, and internal tools that need GPG interoperability without leaving PHP/Laravel.

When to Consider This Package

Consider adoption when:

• The application is Laravel/PHP and needs GPG/OpenPGP encryption or decryption without introducing a separate service.
• The workflow involves existing GPG keys or partner-provided encrypted files, including symmetric passphrase-encrypted files after 1.1.0.
• The scope is bounded: a few integrations, moderate file sizes, and a team that can manage secrets and error handling properly.
• You can store symmetric passphrases in a secrets manager, enforce access control, and avoid putting secrets in code or plain environment files.
• You accept the package as an implementation aid and will add your own validation, audit logging, retries, and monitoring.

Look elsewhere or supplement heavily when:

• You need FIPS-validated cryptography, HSM-backed keys, formal key lifecycle management, key escrow, or multi-tenant key isolation.
• You need high-volume streaming, very large files, or strict throughput/SLA guarantees.
• You need a managed encryption service, UI for key ceremonies, or vendor-supported compliance evidence.
• Symmetric passphrase distribution and rotation cannot be handled securely.
• The product needs broader envelope encryption, field-level encryption, or non-GPG formats rather than OpenPGP interoperability.
• The package’s maintenance, test coverage, supported GPG versions, and large-file behavior have not been reviewed.

How to Pitch It (Stakeholders)

Executive summary: The 1.1.0 release adds symmetric GPG decryption to a Laravel/PHP package, extending it from public-key workflows to passphrase-based file decryption. This can accelerate partner integrations and secure-file ingestion where vendors still use GPG, reducing custom scripting and time-to-market for specific workflows. It is not a replacement for a KMS/HSM or enterprise key-management platform; it should be paired with secret management, access controls, and audit logging.

Engineering summary: Adopt for narrow Laravel GPG integration, especially where symmetric decryption is now required. Wrap the package behind an internal service, externalize passphrases, validate inputs, handle failures explicitly, and test against real partner files. Revisit if scale, compliance, or key-lifecycle requirements grow.

Security/compliance summary: Symmetric support increases practical coverage but raises the bar for secret handling. Require passphrases to live in a secrets manager, enforce least-privilege access, rotate secrets, log decryption events without logging secrets, and document where the package fits within the broader crypto control environment.
