Sealedhelps

Sealedhelps is a term used to describe a packaging approach for software help resources in which the help content is bundled with a cryptographic seal that binds the content to a trusted signer. The seal typically comprises a digital signature created with a private key and metadata such as a content hash, version, and signer identifier. At runtime, the application verifies the seal using a trusted public key; if verification succeeds, the help content is rendered, otherwise access may be blocked or a warning issued.

Purpose and benefits

The primary goal of sealedhelps is to ensure integrity, authenticity, and provenance of help content. By cryptographically sealing the material, developers can deter tampering, guarantee that users see information aligned with the current software version, and enable secure distribution of offline or on-device help. Sealedhelps also supports secure update workflows, allowing new help content to be signed and distributed together with corresponding version metadata.

Implementation considerations

A sealedhelps package typically includes the help content, a seal file or manifest, and a signing key identifier. During verification, the application recomputes the content hash, validates the digital signature, and checks metadata such as version compatibility. Effective use requires robust key management, key rotation plans, and a trusted method to distribute or pin the public key or certificate.

Limitations and scope

The approach relies on trusted key provisioning and can incur additional packaging complexity and performance overhead. If the signing key is compromised, all sealed content is at risk. Sealedhelps is not a universal standard; it is used in some enterprise or offline-first ecosystems to enhance control over help resources.
