Variables

View Source 
var B3 = big.NewInt(3)

We use 3 a couple of times in the decompress algorithm below

View Source 
var ErrChecksumMismatch = errors.New("checksum mismatch")

ErrChecksumMismatch describes an error where decoding failed due to a bad checksum.

View Source 
var ErrMalformedPrivateKey = errors.New("malformed private key")

ErrMalformedPrivateKey describes an error where a WIF-encoded private key cannot be decoded due to being improperly formatted. This may occur if the byte length is incorrect or an unexpected magic number was encountered.
