Media type name: application

Media subtype name: vnd.vnd.majikah.bundle

Required parameters: N/A

Optional parameters: N/A

Encoding considerations: binary

MJKB files are binary containers containing encrypted and compressed data.

Security considerations: MJKB files may contain encrypted binary payloads including user-generated content.
Applications processing MJKB files should validate file structure before parsing
to avoid memory corruption vulnerabilities.

MJKB containers may contain arbitrary data and should be treated as untrusted input.

If the format includes encrypted payloads, implementations must ensure that
cryptographic keys are handled securely and not exposed through metadata or logs.

MJKB files may be large and should be processed using streaming where possible
to avoid denial-of-service conditions due to memory exhaustion.

Interoperability considerations: MJKB is designed as a self-contained binary container format for secure file
transport and storage. Interoperability depends on correct implementation
of the container specification including header parsing, compression,
and cryptographic envelope handling.

Implementations should follow the official MJKB specification to ensure
compatibility across platforms.
