DataHandler.DataRequest

A system focused on creating a reliable system for data sharing between programs (outside of named pipes).

Types

Global configuration for directory- and session-related timeouts and keys.

Properties (static):
- SecureData PublicKey — Key used to encrypt/decrypt metadata (default "Default").
- double ExpiryDuration — Untrusted session/file validity in minutes (default 540).
- double TrustedExpiryDuration — Trusted validity in minutes (default 20160).
- int FailRecoveryCheck — Max allowed recovery failures before lockout (default 5).
- double TimeToNextRecovery — Lockout duration in minutes after too many failures (default 20).
Methods (static):
- SetPublicKey(string newKey, bool makeReadOnly = true)
- SetExpiryDuration(double minutes)
- SetTrustedExpiryDuration(double minutes)
- SetFailRecoveryCheck(int count)
- SetTimeToNextRecovery(double minutes)

Holds common filesystem paths for a given “service” installation.

Properties:
- string CompanyPath
- string MainServicePath
- string ServiceParent
- string Author
- string Software
- string UserSharedResources
- string UserFolder
- string ExePath
- string Program
Constructors:
DirectoryData() { }
DirectoryData(
string companyPath,
string mainServicePath,
string serviceParent,
string author,
string software,
string userSharedResources,
string userFolder,
string exePath,
string program
)

Encapsulates a per-tier encrypted key and its signatures.

Properties:
- byte[] SignedEncryptedTier — Signature over the tier identifier.
- string EncryptedTierPass — AES-encrypted tier password (Base64).
- byte[] SignedTierPass — Signature over the raw tier password.
Constructors:
EncryptedTier() { }
EncryptedTier(byte[] signedEncryptedTier, string encryptedTierPass, byte[] signedTierPass)

Finds the full path of an executable on the system.

Checks whether filePath resides under baseDirectory.

Builds standard folder layout under %LocalAppData%{author}.

Parameters:
- identifier: User or instance ID.
- software, author, programName, serviceParent.
Returns: Task with all constructed paths.

Verifies “CORE.json” integrity by checking a signed “mother path” entry.

Parameters:
- data: DirectoryData containing MainServicePath.
- PublicKey: Key to decrypt and verify signatures.
Returns: Task.

Ensures the executable for programName resides within MainServicePath.

Bootstraps a brand-new “service” instance:

Creates directory hierarchy under %LocalAppData%{author}{serviceParent}{software}.
Writes CORE.json containing public key and signatures for service path & author.
Creates a secret-bank (SecretManager.CreateBank) under UserSharedResources.
Generates tiers number of encrypted tier keys & signatures, saves to Data Tiers.json.
Initializes Allowed Programs and Blacklisted Programs JSON files.
Delegates user/account creation via AccountsWithSessions.

Returns: Task — Recovery key or session identifier from the created account.

Registers a new application under an existing “service”:

Marks a program as blacklisted:

Removes a program from the blacklist:

Removes an allowed program entry:

Composite check that both:

are still intact. Throws on failure.
