@JvmStatic fun doSign(privateKey: PrivateKey, clearData: ByteArray): ByteArray
Generic way to sign ByteArray data with a PrivateKey. Strategy on on identifying the actual signing scheme is based on the PrivateKey type, but if the schemeCodeName is known, then better use doSign(signatureScheme: String, privateKey: PrivateKey, clearData: ByteArray).
privateKey
- the signer's PrivateKey.
clearData
- the data/message to be signed in ByteArray form (usually the Merkle root).
IllegalArgumentException
- if the signature scheme is not supported for this private key.
InvalidKeyException
- if the private key is invalid.
SignatureException
- if signing is not possible due to malformed data or private key.
Return
the digital signature (in ByteArray) on the input message.
@JvmStatic fun doSign(schemeCodeName: String, privateKey: PrivateKey, clearData: ByteArray): ByteArray
Generic way to sign ByteArray data with a PrivateKey and a known schemeCodeName String.
schemeCodeName
- a signature scheme's code name (e.g. ECDSA_SECP256K1_SHA256).
privateKey
- the signer's PrivateKey.
clearData
- the data/message to be signed in ByteArray form (usually the Merkle root).
IllegalArgumentException
- if the signature scheme is not supported.
InvalidKeyException
- if the private key is invalid.
SignatureException
- if signing is not possible due to malformed data or private key.
Return
the digital signature (in ByteArray) on the input message.
@JvmStatic fun doSign(signatureScheme: SignatureScheme, privateKey: PrivateKey, clearData: ByteArray): ByteArray
Generic way to sign ByteArray data with a PrivateKey and a known Signature.
signatureScheme
- a SignatureScheme object, retrieved from supported signature schemes, see Crypto.
privateKey
- the signer's PrivateKey.
clearData
- the data/message to be signed in ByteArray form (usually the Merkle root).
IllegalArgumentException
- if the signature scheme is not supported for this private key.
InvalidKeyException
- if the private key is invalid.
SignatureException
- if signing is not possible due to malformed data or private key.
Return
the digital signature (in ByteArray) on the input message.
@JvmStatic fun doSign(keyPair: KeyPair, signableData: SignableData): TransactionSignature
Generic way to sign SignableData objects with a PrivateKey. SignableData is a wrapper over the transaction's id (Merkle root) in order to attach extra information, such as a timestamp or partial and blind signature indicators.
keyPair
- the signer's KeyPair.
signableData
- a SignableData object that adds extra information to a transaction.
IllegalArgumentException
- if the signature scheme is not supported for this private key.
InvalidKeyException
- if the private key is invalid.
SignatureException
- if signing is not possible due to malformed data or private key.
Return
a TransactionSignature object than contains the output of a successful signing, signer's public key and
the signature metadata.
