CRYPTO NEWS

Any software mirroring an unencrypted drive resulting in an encrypted mounted drive?

Have your ever heard of a cryptography software that would mount a drive (file/foldernames and content encrypted) reflecting the content of another unenecrypted source drive ?
The purpose is to use that mounted drive as a source for online backup (and not online storage) service like Backblaze (not Backblaze B2).
With online storage services, the solution would be Boxcryptor or Cryptomator as ou can map the distant storage area as a local drive (and then drag and drop files you want to upload), but with Backblaze you can’t do that.

Chainlink AggregatorV3Interface: how would we know that a parameter can be passed into the AggregatorV3Interface constructor?

AggregatorV3Interface priceFeed = AggregatorV3Interface(0xD4a33860578De61DBAbDc8BFdb98FD742fA7028e); When I look into the code of AggregatorV3Interface.sol (https://github.com/smartcontractkit/chainlink/blob/develop/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol) // SPDX-License-Identifier: MIT pragma solidity ^0.8.0; interface AggregatorV3Interface { function decimals() external view returns (uint8); function description() external view returns (string memory); function version() external view returns (uint256); function getRoundData(uint80 _roundId) external view returns ( uint80 roundId, int256 answer, uint256 startedAt, uint256::Listen

AggregatorV3Interface priceFeed = AggregatorV3Interface(0xD4a33860578De61DBAbDc8BFdb98FD742fA7028e);

When I look into the code of AggregatorV3Interface.sol (https://github.com/smartcontractkit/chainlink/blob/develop/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol)

// SPDX-License-Identifier: MIT pragma solidity ^0.8.0;      interface AggregatorV3Interface {           function decimals() external view returns (uint8);            function description() external view returns (string memory);            function version() external view returns (uint256);            function getRoundData(uint80 _roundId)         external         view         returns (           uint80 roundId,           int256 answer,           uint256 startedAt,           uint256 updatedAt,           uint80 answeredInRound         );            function latestRoundData()         external         view         returns (           uint80 roundId,           int256 answer,           uint256 startedAt,           uint256 updatedAt,           uint80 answeredInRound         ); }   

I don’t see / understand where in the definition of the code that it can accept contract.

Where can we verify/check this?
