Method Detail

createWithoutVerification

public static SlhDsaPrivateKey createWithoutVerification(SlhDsaPublicKey slhDsaPublicKey,
                                                         SecretBytes privateKeyBytes)
                                                  throws java.security.GeneralSecurityException

Throws:

java.security.GeneralSecurityException

getPublicKey

public SlhDsaPublicKey getPublicKey()

Description copied from class: SignaturePrivateKey

Returns the SignaturePublicKey, which contains the verify function of the digital signature primitive.

Specified by:

getPublicKey in interface PrivateKey

Specified by:

getPublicKey in class SignaturePrivateKey

getParameters

public SlhDsaParameters getParameters()

Description copied from class: SignaturePrivateKey

Returns the parameters of this key.

Returns the same as getPublicKey().getParameters().

Overrides:

getParameters in class SignaturePrivateKey

getPrivateKeyBytes

public SecretBytes getPrivateKeyBytes()

equalsKey

public boolean equalsKey(Key o)

Description copied from class: Key

Returns true if the key is guaranteed to be equal to other.

Implementations are required to do this in constant time.

Note: this is allowed to return false even if two keys are guaranteed to represent the same function, but are represented differently. For example, a key is allowed to internally store the number of zero-bytes used as padding when a large number is represented as a byte array, and use this in the comparison.

Note: Tink Key objects should typically not override hashCode (because it could risk leaking key material). Hence, they typically also should not override equals.
