Constructor Detail

IdentityDarc

public IdentityDarc(DarcProto.IdentityDarc proto)

Instantiates a IdentityDarc given its protobuf representation.

Parameters:

proto - the protobuf representation of the IdentityDarc

IdentityDarc

public IdentityDarc(DarcId darcBaseID)

Instantiates a IdentityDarc given a darc-id.

Parameters:

darcBaseID - the source DarcId

IdentityDarc

public IdentityDarc(Darc darc)

Instantiates a IdentityDarc given a darc.

Parameters:

darc - the source Darc

Method Detail

verify

public boolean verify(byte[] msg,
                      byte[] signature)

Returns true if the verification of signature on the sha-256 of msg is successful or false if not.

Specified by:

verify in interface Identity

Parameters:

msg - the message

signature - the signature

Returns:

true if the signature is correct

toProto

public DarcProto.Identity toProto()

Creates a protobuf-representation of the implementation. The protobuf representation has to hold all necessary fields to represent any of the identity implementations.

Specified by:

toProto in interface Identity

Returns:

a protobuf-representation of the IdentityDarc

getDarcId

public DarcId getDarcId()

Return ID of DARC

Returns:

ID of DARC

equals

public boolean equals(Object o)

Specified by:

equals in interface Identity

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Specified by:

toString in interface Identity

Overrides:

toString in class Object

typeString

public String typeString()

Specified by:

typeString in interface Identity

getPublicBytes

public byte[] getPublicBytes()

Description copied from interface: Identity

Get the public identifier in bytes. The returned value is not a serialisation of the identity.

Specified by:

getPublicBytes in interface Identity
