Constructors

SQLiteEncryptedBlobCache(string, IEncryptionProvider?, IScheduler?)

Initializes a new instance of the SQLiteEncryptedBlobCache class.

public SQLiteEncryptedBlobCache(string databaseFile, IEncryptionProvider? encryptionProvider = null, IScheduler? scheduler = null)

Parameters

databaseFile string

The location of the database.

encryptionProvider IEncryptionProvider

The provider which encrypts and decrypts values.

scheduler IScheduler

A scheduler to perform the operations on.

Exceptions

Exception

If there is no encryption provider available.

Methods

AfterReadFromDiskFilter(byte[], IScheduler)

This method is called immediately after reading any data to disk. Override this in encrypting data stores in order to decrypt the data.

protected override IObservable<byte[]> AfterReadFromDiskFilter(byte[] data, IScheduler scheduler)

Parameters

data byte[]

The byte data that has just been read from disk.

scheduler IScheduler

The scheduler to use if an operation has to be deferred. If the operation can be done immediately, use Observable.Return and ignore this parameter.

Returns

IObservable<byte[]>

A Future result representing the decrypted data.

BeforeWriteToDiskFilter(byte[], IScheduler)

This method is called immediately before writing any data to disk. Override this in encrypting data stores in order to encrypt the data.

protected override IObservable<byte[]> BeforeWriteToDiskFilter(byte[] data, IScheduler scheduler)

Parameters

data byte[]

The byte data about to be written to disk.

scheduler IScheduler

The scheduler to use if an operation has to be deferred. If the operation can be done immediately, use Observable.Return and ignore this parameter.

Returns

IObservable<byte[]>

A Future result representing the encrypted data.
