方法详细资料

toHex

public static String toHex(byte[] b,
                           boolean leading0x)

Output byte representation as hexadecimal representation.

参数:

b - Bytes to encode to hexadecimal representation.

leading0x - If true, return with leading "0x".

返回:

Hexadecimal representation of specified bytes.

encode

public static String encode(byte[] b,
                            boolean leading0x)

Output byte representation as hexadecimal representation. Alias for toHex() method.

参数:

b - Bytes to encode to hexadecimal representation.

leading0x - If true, return with leading "0x".

返回:

Hexadecimal representation of specified bytes.

fromHex

public static byte[] fromHex(String hexStr)

Decode hexadecimal-encoded string and return raw byte array. Important note: This method preserves leading 0 filled bytes on the conversion process, which is important for cryptographic operations in dealing with things like keys, initialization vectors, etc. For example, the string "0x0000face" is going to return a byte array whose length is 4, not 2.

参数:

hexStr - Hexadecimal-encoded string, with or without leading "0x".

返回:

The equivalent byte array.

decode

public static byte[] decode(String hexStr)

Decode hexadecimal-encoded string and return raw byte array. Alias for fromHex() method.

参数:

hexStr - Hexadecimal-encoded string, with or without leading "0x".

返回:

The equivalent byte array.
