signedWith

public TransactionMessage.Builder signedWith(KeyPair keys)

Sets the Ed25519 key pair to use to sign the message.

Parameters:

keys - a key pair with a private and public keys. The public key is included in the message as an author key of the message. The private key is used for signing the message, but not included in it

signedWith

public TransactionMessage.Builder signedWith(KeyPair keys, CryptoFunction crypto)

Sets the key pair and the crypto function to use to sign the message.

Parameters:

keys - a key pair with a private and public keys. The public key is included in the message as an author key of the message. The private key is used for signing the message, but not included in it

crypto - a cryptographic function to use

sign

public TransactionMessage sign(KeyPair keys)

Signs the message with the given Ed25519 keys, creating a new signed binary transaction message. A shorthand for signedWith(keys).build().

Parameters:

keys - a key pair to sign the message

Returns:

a new signed binary transaction message

Throws:

IllegalStateException - if any field weren't set

IllegalArgumentException - if the public key has wrong size

build

public TransactionMessage build()

Signs the message, creating a new signed binary transaction message.

Returns:

a new signed binary transaction message

Throws:

IllegalStateException - if any field weren't set

IllegalArgumentException - if the public key has wrong size
