Parameters configuration for SCRYPT
const ( // Compressed denotes the public key is in compressed form Compressed = 0x20 // Uncompressed denotes the public key is in uncompressed form Uncompressed = 0x00 // NoLotSequence is employed when no lot number or sequence number is included NoLotSequence = 0x00 // WithLotSequence is the opposite to NoLotSequence WithLotSequence = 0x04 )
flag bits
const ConfirmationMagicLen = 5
ConfirmationMagicLen is the length of magic bytes to encode the confirmation code returning to owner from the generator
const MagicLen = 8
MagicLen is the length of magic bytes to encode the intermediate passphrase string
const RawConfirmationCodeLen = 1 + 4 + 8 + 33
RawConfirmationCodeLen is the length of confirmation code without encoding and the magic prefix
const RawEncryptedKeyLen = 1 + 4 + 8 + 8 + 16
RawEncryptedKeyLen is the length of encrypted private key without base58 encoding and trimming out the version prefix
const VersionLen = 2
VersionLen is length of version prefix for encrypting private key according to EC-Multiply mode
Variables ¶
var ConfirmationMagicCode = []byte{0x64, 0x3B, 0xF6, 0xA8, 0x9A}
ConfirmationMagicCode prepend to the raw confirmation code to make up the "cfrm38" prefix in the final base58-encoding string
var Version = []byte{0x01, 0x43}
Version is the object identifier prefix for EC-Multiply encryption mode
Functions ¶
func DecodeLotSequence ¶
DecodeLotSequence decodes the lot and sequence numbers out of the given byte sequence. The first 4 bytes of lotSequence would be employed for decoding.
func Decrypt ¶
Decrypt decrypts the derived private key out of the base58-encoded encrypted string based on the owner's passphrase. And if applicable, the corresponding lot and sequence number can be recovered using the LotSequenceFromEncryptedKey function.
func EncodeLotSequence ¶
EncodeLotSequence encodes the lot and sequence numbers into the given lotSequence buffer. And the first 32 bits consist of the least significant 20 bits of lot following by the 12 bits of sequence.
func Encrypt ¶
Encrypt derives an encrypted private key from the given passphrase code and return the resultant encrypted private key and confirmation code
func EncryptPassphrase ¶
EncryptPassphrase generates a intermediate passphrase code from the given one provided by owner.
func EncryptPassphraseX ¶
EncryptPassphraseX works similarly to EncryptPassphrase, except that the ownerEntropy consists of 4 byte owner salt and 4 byte buffer encoded from the lot number and the sequence number.
func GenerateConfirmationCode ¶
func GenerateConfirmationCode(flag byte, addrHash, ownerEntropy, b, derivedHalf1, derivedHalf2 []byte) string
GenerateConfirmationCode derives the corresponding confirmation code based on the intermediate information during private key encryption. Especially, both derivedHalf1 and derivedHalf2 should be of exact length as 32 bytes. Otherwise, the program would behave unexpectedly.
func LotSequenceFromConfirmationCode ¶
LotSequenceFromConfirmationCode decodes the lot number and sequence number out of the given passphrase code.
func LotSequenceFromEncryptedKey ¶
LotSequenceFromEncryptedKey decodes the lot number and sequence number out of the given encrypted private key.
func RecoverAddress ¶
RecoverAddress recovers the generated address out of the given confirmation code based on the given passphrase. If applicable, the corresponding lot and sequence number can be recovered from this passphrase code using LotSequenceFromConfirmationCode function.
