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.

Method	Type	Description
PrivateKey.generateED25519()	PrivateKey	Generates an Ed25519 private key
PrivateKey.generateED25519().getPublicKey()	PublicKey	Derive a public key from this Ed25519 private key
PrivateKey.generateED25519().publicKey()	PublicKey	Derive a public key from this Ed25519 private key
PrivateKey.generateED25519().publicKey().toAccountId(<shard>,<realm>)	long, long	Contruct an alias account ID from a alias public key address
[DEPRECATED]PrivateKey.generate()	PrivateKey	Generates an Ed25519 private key

Java

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

ECDSA (secp256k1_)

Create a new ECDSA (secp256k1) key pair used to sign transactions and queries on a 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.

Method	Type	Description
PrivateKey.generateECDSA()	PrivateKey	Generates an ECSDA private key
PrivateKey.generateECDSA().getPublicKey()	PublicKey	Derive a public key from this ECDSA private key
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

Java

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

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