DecryptFileWithStream ( Sodium.KeyPair keyPair, string inputFile, string outputFolder, bool overWrite = false ) : string

Decrypts a file with libsodium and protobuf-net.
DecryptFileWithStream ( byte recipientPrivateKey, string inputFile, string outputFolder, bool overWrite = false ) : string

Decrypts a file with libsodium and protobuf-net.
DecryptFileWithStreamAsync ( Sodium.KeyPair keyPair, string inputFile, IProgress decryptionProgress = null, CancellationToken cancellationToken = default(CancellationToken) ) : Task

Decrypts a file asynchron into memory with libsodium and protobuf-net.

This method can throw an OutOfMemoryException when there is not enough ram to hold the DecryptedFile!
