Response If opmethod is invoke, the transactionID encrypted and encoded using Base64 is returned. If opmethod is query, the query result returned by the chaincode is also encrypted and encoded using Base64.
The value after -a is encrypted, while the one after -b is in plaintext. Parent topic: Homomorphic Encryption
Requirements Data such as user identities must be encrypted to protect the information against brute force attack. Quick information queries based on identities must be supported.
You can choose from multiple storage services to store the encrypted data to be exchanged. The one calling the API is responsible for storing ciphertexts to publicly accessible storage devices. Roles Trusted data exchange involves two roles: data owner and data applicant.
The encrypted balance amount is added to the users' ledgers. A storage structure is defined in the demo.
For an MSP private key: In the insert function of the main.go file, invoke the function: encryptedbytekey,_:= GetPrivateKeyBytes(org) // Retrieve the encrypted MSP private key from the specified directory in the configuration file. // Decrypt encryptedbytekey using the specified
The returned invocation result is TransactionID encrypted using Base64, and the query result is data encrypted using Base64. The code is for reference only. You can use this project code to understand how to invoke RESTful APIs. Parent topic: Demos
For an MSP private key, in the genFabricUser function of the FabricHelper file, invoke the function: // Retrieve the encrypted MSP private key from the specified directory in the configuration file.
Once the customer opens a bank account, the reviewed trusted identity information is recorded to the blockchain and is encrypted and shared to other banks. Then, the customer can apply for accounts with other banks without repeating the approval process.
