Functions

func CheckDecode 

func CheckDecode(input string) (result []byte, version []byte, err error)

CheckDecode decodes a string that was encoded with CheckEncode and verifies the checksum.

func CheckEncode 

func CheckEncode(input []byte, version []byte) string

CheckEncode prepends a version byte and appends a four byte checksum.

func DecodeAddress 

func DecodeAddress(addr string, defaultNet *chaincfg.Params) (btcutil.Address, error)

DecodeAddress decodes the string encoding of an address and returns the Address if addr is a valid encoding for a known address type.

The zcash network the address is associated with is extracted if possible.

func ExtractPkScriptAddrs 

func ExtractPkScriptAddrs(pkScript []byte, chainParams *chaincfg.Params) (btcutil.Address, error)

ExtractPkScriptAddrs returns the type of script, addresses and required signatures associated with the passed PkScript. Note that it only works for 'standard' transaction script types. Any data such as public keys which are invalid are omitted from the results.

func GetCredentials 

func GetCredentials(repoPath string) (username, password string, err error)

func PayToAddrScript 

func PayToAddrScript(addr btcutil.Address) ([]byte, error)

PayToAddrScript creates a new script to pay a transaction output to a the specified address.

func StartNotificationListener 

func StartNotificationListener(client *btcrpcclient.Client, params *chaincfg.Params, listeners []func(wallet.TransactionCallback))

Types

type AddressPubKeyHash 

type AddressPubKeyHash struct {
	// contains filtered or unexported fields
}

AddressPubKeyHash is an Address for a pay-to-pubkey-hash (P2PKH) transaction.

func NewAddressPubKeyHash 

func NewAddressPubKeyHash(pkHash []byte, net *chaincfg.Params) (*AddressPubKeyHash, error)

NewAddressPubKeyHash returns a new AddressPubKeyHash. pkHash mustbe 20 bytes.

func (*AddressPubKeyHash) EncodeAddress 

func (a *AddressPubKeyHash) EncodeAddress() string

EncodeAddress returns the string encoding of a pay-to-pubkey-hash address. Part of the Address interface.

func (*AddressPubKeyHash) Hash160 

func (a *AddressPubKeyHash) Hash160() *[ripemd160.Size]byte

Hash160 returns the underlying array of the pubkey hash. This can be useful when an array is more appropiate than a slice (for example, when used as map keys).

func (*AddressPubKeyHash) IsForNet 

func (a *AddressPubKeyHash) IsForNet(net *chaincfg.Params) bool

IsForNet returns whether or not the pay-to-pubkey-hash address is associated with the passed zcash network.

func (*AddressPubKeyHash) ScriptAddress 

func (a *AddressPubKeyHash) ScriptAddress() []byte

ScriptAddress returns the bytes to be included in a txout script to pay to a pubkey hash. Part of the Address interface.

func (*AddressPubKeyHash) String 

func (a *AddressPubKeyHash) String() string

String returns a human-readable string for the pay-to-pubkey-hash address. This is equivalent to calling EncodeAddress, but is provided so the type can be used as a fmt.Stringer.

type AddressScriptHash 

type AddressScriptHash struct {
	// contains filtered or unexported fields
}

AddressScriptHash is an Address for a pay-to-script-hash (P2SH) transaction.

func NewAddressScriptHash 

func NewAddressScriptHash(serializedScript []byte, net *chaincfg.Params) (*AddressScriptHash, error)

NewAddressScriptHash returns a new AddressScriptHash.

func NewAddressScriptHashFromHash 

func NewAddressScriptHashFromHash(scriptHash []byte, net *chaincfg.Params) (*AddressScriptHash, error)

NewAddressScriptHashFromHash returns a new AddressScriptHash. scriptHash must be 20 bytes.

func (*AddressScriptHash) EncodeAddress 

func (a *AddressScriptHash) EncodeAddress() string

EncodeAddress returns the string encoding of a pay-to-script-hash address. Part of the Address interface.

func (*AddressScriptHash) Hash160 

func (a *AddressScriptHash) Hash160() *[ripemd160.Size]byte

Hash160 returns the underlying array of the script hash. This can be useful when an array is more appropiate than a slice (for example, when used as map keys).

func (*AddressScriptHash) IsForNet 

func (a *AddressScriptHash) IsForNet(net *chaincfg.Params) bool

IsForNet returns whether or not the pay-to-script-hash address is associated with the passed zcash network.

func (*AddressScriptHash) ScriptAddress 

func (a *AddressScriptHash) ScriptAddress() []byte

ScriptAddress returns the bytes to be included in a txout script to pay to a script hash. Part of the Address interface.

func (*AddressScriptHash) String 

func (a *AddressScriptHash) String() string

String returns a human-readable string for the pay-to-script-hash address. This is equivalent to calling EncodeAddress, but is provided so the type can be used as a fmt.Stringer.

	AddressPubKeyHash []byte
	AddressScriptHash []byte
	ZAddress          []byte
}
