Method Detail

createWithoutVerification

public static MlDsaPrivateKey createWithoutVerification(MlDsaPublicKey mlDsaPublicKey,
                                                        SecretBytes privateSeed)
                                                 throws java.security.GeneralSecurityException

Throws:

java.security.GeneralSecurityException

getPrivateSeed

public SecretBytes getPrivateSeed()

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.

equalsKey in class Key

getParameters

public MlDsaParameters getParameters()

Description copied from class: SignaturePrivateKey

Returns the parameters of this key.

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

Overrides:

getParameters in class SignaturePrivateKey

getPublicKey

public MlDsaPublicKey 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
