Method Details

engineInitVerify

protected void engineInitVerify(PublicKey publicKey)
                         throws InvalidKeyException

Specified by:

engineInitVerify in class SignatureSpi

Throws:

InvalidKeyException

engineInitSign

protected void engineInitSign(PrivateKey privateKey,
 SecureRandom random)
                       throws InvalidKeyException

Overrides:

engineInitSign in class SignatureSpi

Throws:

InvalidKeyException

engineInitSign

protected void engineInitSign(PrivateKey privateKey)
                       throws InvalidKeyException

Specified by:

engineInitSign in class SignatureSpi

Throws:

InvalidKeyException

engineUpdate

protected void engineUpdate(byte b)
                     throws SignatureException

Note the one-time key this signature will use is claimed here, at the first update(), rather than at sign(): getSigner() takes the signing context from the key, which advances its index. A Signature that is initialised and updated and then abandoned therefore spends an index without producing a signature. That is the safe direction for a one-time scheme - the alternative risks issuing the same one-time key twice - but it is worth knowing when budgeting a key's usages.
