Generate a new key pair

ED25519

Create a new ED25519 key pair used to sign transactions and queries on the Hedera network. The private key is kept confidential and is used to sign transactions that modify the state of an account, topic, token, smart contract, or file entity on the network. The public key can be shared with other users on the network.

[DEPRECATED]PrivateKey.generate()

PrivateKey

Generates an Ed25519 private key

PrivateKey privateKey = PrivateKey.generateED25519();
PublicKey publicKey = privateKey.getPublicKey();

System.out.println("private key = " + privateKey);
System.out.println("public key = " + publicKey);

Sample Output:

private key = 3030020100300706052b8104000a04220420818c50766e025db403416421cb4a16d26ab0044b7f1a1e45513cef2c86123b91

PrivateKey.generateECDSA().publicKey()

PublicKey

Derive a public key from this ECDSA private key

PrivateKey.generateECDSA().publicKey().toAccountId(<shard>, <realm>)

long, long

Contructs an account ID from an account alias public key

PrivateKey privateKey = PrivateKey.generateECDSA();
PublicKey publicKey = privateKey.getPublicKey();

System.out.println("private key = " + privateKey);
System.out.println("public key = " + publicKey);

Sample Output:
