com.jn.langx.codec.base58.Base58

public class Base58
extends Object

The operations contained in this class are confined to their methods and are entirely thread-safe. In fact, all of the methods are implemented statically, and the instance-bound encode(byte[]) and decode(String) methods are non-static simply to accommodate possible future compatibility with Apache Commons-Codec.

Base58

public Base58()

方法详细资料

encodeToString

public static String encodeToString(byte[] source)

Encode a stream of MSB-ordered bytes into Base58. Automatically pads negative numbers with a leading zero byte.

参数:

source - the bytes to be encoded

返回:

the encoded representation

encode

public String encode(byte[] source)

encodeToString

public static String encodeToString(long value)

Convenience method to encode a long value. Converts the value into a byte array and calls encode(byte[]).

参数:

value - the number to be encoded

返回:

the encoded representation

encode

public String encode(long value)

decodeString

public static byte[] decodeString(String source)

Decode a Base58-encoded value into bytes. Note that this method will return the fewest number of bytes necessary to completely represent the value; if the value may be smaller than the size of the target type, use decode(String, int) to front-pad to a specific length. If the original value encoded was negative, this method will return a leading zero byte added as padding.

参数:

source - a Base58-encoded value

返回:

the bytes represented by the value, unpadded

decode

public byte[] decode(String source)

doDecode

public static byte[] doDecode(String source,
                              int numBytes)

Decode a Base58-encoded value into the specified number of bytes, MSB first (with zero-padding at the front).

参数:

source - a Base58-encoded value

numBytes - the size of the byte array to be returned

返回:

the bytes represented by the value, zero-padded at the front

decode

public byte[] decode(String source,
                     int numBytes)
