方法详细资料

encode

public static byte[] encode(byte[] data)

decode

public static byte[] decode(byte[] data)

decode

public static byte[] decode(java.lang.String data)

encodeToString

public static final java.lang.String encodeToString(byte[] sArr,
                                                    boolean lineSep)

Encodes a raw byte array into a BASE64 String representation i accordance with RFC 2045.

参数:

sArr - The bytes to convert. If null or length 0 an empty array will be returned.

lineSep - Optional "\r\n" after 76 characters, unless end of file.
No line separator will be in breach of RFC 2045 which specifies max 76 per line but will be a little faster.

返回:

A BASE64 encoded array. Never null.

encodeToChar

public static final char[] encodeToChar(byte[] sArr,
                                        boolean lineSep)

Encodes a raw byte array into a BASE64 char[] representation i accordance with RFC 2045.

参数:

sArr - The bytes to convert. If null or length 0 an empty array will be returned.

lineSep - Optional "\r\n" after 76 characters, unless end of file.
No line separator will be in breach of RFC 2045 which specifies max 76 per line but will be a little faster.

返回:

A BASE64 encoded array. Never null.
