A25 is a type for a 25 byte (not base58 encoded) bitcoin address.

func ParseBTCAddress 

func ParseBTCAddress(address string) (btc *A25, err error)

ParseBTCAddress decodes a base58 encoded bitcoin address and returns an error if the checksum is invalid. See https://rosettacode.org/wiki/Bitcoin/address_validation#Go

func (*A25) ComputeChecksum 

func (a *A25) ComputeChecksum() (c [4]byte)

ComputeChecksum returns a four byte checksum computed from the first 21 bytes of the address. The embedded checksum is not updated.

func (*A25) Decode 

func (a *A25) Decode(s []byte) error

Decode takes a base58 encoded address and decodes it into the receiver. Errors are returned if the argument is not valid base58 or if the decoded value does not fit in the 25 byte address. The address is not otherwise checked for validity.

func (*A25) EmbeddedChecksum 

func (a *A25) EmbeddedChecksum() (c [4]byte)

func (*A25) HasValidChecksum 

func (a *A25) HasValidChecksum() bool

Validate an A25 checksum.

func (*A25) IsMainnet 

func (a *A25) IsMainnet() bool

Mainnet addresses are assumed to start with '1' or '3'.

func (*A25) IsTestnet 

func (a *A25) IsTestnet() bool
