Method Detail

encode

public static java.lang.String encode(byte[] input)

Encodes the given bytes as a base58 string (no checksum is appended).

Parameters:

input - the bytes to encode

Returns:

the base58-encoded string

encodeChecked

public static java.lang.String encodeChecked(int version,
                                             byte[] payload)

Encodes the given version and bytes as a base58 string. A checksum is appended.

Parameters:

version - the version to encode

payload - the bytes to encode, e.g. pubkey hash

Returns:

the base58-encoded string

decode

public static byte[] decode(java.lang.String input)
                     throws AddressFormatException

Decodes the given base58 string into the original data bytes.

Parameters:

input - the base58-encoded string to decode

Returns:

the decoded data bytes

Throws:

AddressFormatException - if the given string is not a valid base58 string

decodeToBigInteger

public static java.math.BigInteger decodeToBigInteger(java.lang.String input)
                                               throws AddressFormatException

Throws:

AddressFormatException

decodeChecked

public static byte[] decodeChecked(java.lang.String input)
                            throws AddressFormatException

Decodes the given base58 string into the original data bytes, using the checksum in the last 4 bytes of the decoded data to verify that the rest are correct. The checksum is removed from the returned data.

Parameters:

input - the base58-encoded string to decode (which should include the checksum)

Throws:

AddressFormatException - if the input is not base 58 or the checksum does not validate.
