encodeToString

public static java.lang.String encodeToString(byte[] buffer,
                                              int off,
                                              int len,
                                              int flags)

Encodes a raw byte array into a Base64 String.

参数:

buffer - buffer containing the input. If length 0, an empty array will be returned.

off - the offset into the buffer of the input bytes

len - the length of the input, in bytes

flags - indicating the desired encoding options

返回:

a Base64-encoded String. Never null.

encodeToBytes

public static byte[] encodeToBytes(byte[] buffer,
                                   int bytesOff,
                                   int bytesLen,
                                   int flags)

Encodes a raw byte array into a Base64 byte[].

参数:

buffer - buffer containing the input. If length 0, an empty array will be returned.

bytesOff - the offset into the buffer of the input bytes

bytesLen - the length of the input, in bytes

flags - indicating the desired encoding options

返回:

a Base64-encoded array. Never null.
