方法详细资料

create_confidential_tx

public static byte[] create_confidential_tx(byte[] tx_json,
                                            int tx_len)

Create a confidential tx. In: tx_json: a pointer to tx json string. In: tx_len: the size of tx json string. Out: error: output a ExternError. 'code' 0 represents success, all other values represent failure. If the `code` field is nonzero, there should always be a message, and if it's zero, the message will always be null. Returns: if success, return pointer and len of tx. Otherwise return null.

create_confidential_tx_by_rlp

public static byte[] create_confidential_tx_by_rlp(byte[] data,
                                                   int data_len)

Create a confidential tx. In: tx_json: a pointer to tx rlp stream. In: tx_len: the size of tx rlp stream. Out: error: output a ExternError. 'code' 0 represents success, all other values represent failure. If the `code` field is nonzero, there should always be a message, and if it's zero, the message will always be null. Returns: if success, return pointer and len of tx. Otherwise return null.

confidential_tx_verify

public static byte[] confidential_tx_verify(byte[] tx_data,
                                            int tx_len)

Verify the confidential tx. In: tx_data: a pointer to tx string generated by 'create_confidential_tx'. In: tx_len: the size of tx string. Out: error: output a ExternError. 'code' 0 represents success, all other values represent failure. If the `code` field is nonzero, there should always be a message, and if it's zero, the message will always be null. Returns: if success, return pointer and len of tx log. Otherwise return null.

create_keypair

public static byte[] create_keypair(byte[] sk_data,
                                    int sk_len)

Create a key pair for view key and spend key. Note: if sk_data is null or sk_len is 0, 'create_keypair' will output a random key pair. In: sk_data: a pointer to sk string of "user's input". In: sk_len: the size of sk string. Out: error: output a ExternError. 'code' 0 represents success, all other values represent failure. If the `code` field is nonzero, there should always be a message, and if it's zero, the message will always be null. Returns: if success, return pointer and len of key pair json string. Otherwise return null. The output key pair format is rlp encoding.

is_note_owner

public static boolean is_note_owner(byte[] ephemeral_pk_data,
                                    int ephemeral_pk_len,
                                    byte[] sign_pk_data,
                                    int sign_pk_len,
                                    byte[] spend_pk_data,
                                    int spend_pk_len,
                                    byte[] view_sk_data,
                                    int view_sk_len)

Is the owner of note. In: ephemeral_pk_data: a pointer to ephemeral_pk. In: ephemeral_pk_len: the size of ephemeral_pk. In: sign_pk_data: a pointer to sign_pk. In: sign_pk_len: the size of sign_pk. In: view_sk_data: a pointer to view_sk. In: view_sk_len: the size of view_sk. Out: error: output a ExternError. 'code' 0 represents success, it is the correct owner. All other values represent failure. If the `code` field is nonzero, there should always be a message, and if it's zero, the message will always be null.

decrypt_note

public static byte[] decrypt_note(byte[] cipher_data,
                                  int cipher_len,
                                  byte[] view_sk_data,
                                  int view_sk_len)

Decrypt the quatity and blinding. In: cipher_data: a pointer to ephemeral_pk. In: cipher_len: the size of ephemeral_pk. In: view_sk_data: a pointer to view_sk. In: view_sk_len: the size of view_sk. Out: error: output a ExternError. 'code' 0 represents success, all other values represent failure. If the `code` field is nonzero, there should always be a message, and if it's zero, the message will always be null. Returns: if success, return pointer and len of quatity and blinding. Otherwise return null. Using the rlp encoding of quatity and blinding.
