Method Detail

getDigest

public String getDigest(String seed,
                        int security,
                        int index)
                 throws ArgumentException

Parameters:

seed - Tryte-encoded seed. It should be noted that this seed is not transferred.

security - Secuirty level of private key / seed.

index - Key index to start search from. If the index is provided, the generation of the address is not deterministic.

Returns:

trytes

Throws:

ArgumentException - is thrown when the specified security level is not valid.

addAddressDigest

public String addAddressDigest(String digestTrytes,
                               String curlStateTrytes)

Initiates the generation of a new multisig address or adds the key digest to an existing one

Parameters:

digestTrytes -

curlStateTrytes -

Returns:

trytes.

getKey

public String getKey(String seed,
                     int index,
                     int security)
              throws ArgumentException

Gets the key value of a seed

Parameters:

seed - Tryte-encoded seed. It should be noted that this seed is not transferred

index - Key index to start search from. If the index is provided, the generation of the address is not deterministic.

Returns:

trytes.

Throws:

ArgumentException - is thrown when the specified security level is not valid.

Generates a new address

Parameters:

curlStateTrytes -

Returns:

address

validateAddress

public boolean validateAddress(String multisigAddress,
                               int[][] digests)

Validates a generated multisig address

Parameters:

multisigAddress -

digests -

Returns:

true if the digests turn into multiSigAddress, otherwise false

addSignature

public Bundle addSignature(Bundle bundleToSign,
                           String inputAddress,
                           String keyTrytes)

Parameters:

bundleToSign -

inputAddress -

keyTrytes -

Returns:

Returns bundle trytes.
