Class EncryptedArgumentsCli

java.lang.Object

net.finmath.decryptionoracle.execution.cli.EncryptedArgumentsCli

public class EncryptedArgumentsCli
extends Object

CLI to construct EncryptedHashedArguments from plaintext ABI-encoded arguments, ready to be pasted into Remix. The Solidity side is: struct ArgsDescriptor { address[] eligibleCaller; bytes argsPlain; } struct EncryptedHashedArguments { bytes32 argsHash; // keccak256(argsPlain) bytes32 publicKeyId; // e.g. keccak256(publicKey) bytes ciphertext; // encrypt(abi.encode(ArgsDescriptor)) } This CLI does: 1. Take argsPlain (either as raw hex or UTF-8 string). 2. Build ArgsDescriptor(eligibleCaller[], argsPlain). 3. ABI-encode ArgsDescriptor via web3j (TypeEncoder + DynamicStruct). 4. Encrypt abi.encode(ArgsDescriptor) with an RSA public key (DER). 5. Compute: argsHash = keccak256(argsPlain) publicKeyId = keccak256(publicKey.getEncoded()) ciphertext = RSA-OAEP-SHA256(abi.encode(ArgsDescriptor)) 6. Print everything as 0x-hex and a Remix-ready tuple. Usage example: mvn -q -Dexec.mainClass=net.finmath.decryptionoracle.execution.cli.EncryptedArgumentsCli \ -Dexec.args="\ --pubkey src/main/resources/oracle-public-key.der \ --eligible 0xAbc123... \ --plain-hex 0x01020304" \ exec:java
