Method Detail

decode

public static byte[] decode(String base64String,
                            boolean ignoreInvalidChars)
                     throws IOException

Read the bytes encoded in a Base64 encoded String.

Parameters:

base64String - The String containing the Base64 encoded bytes.

ignoreInvalidChars - Whether to ignore invalid Base64 characters.

Returns:

byte[] The raw bytes contained in the base64String.

Throws:

IOException - Failed to read the Base64 data.

decodeToStream

public static InputStream decodeToStream(String base64String,
                                         boolean ignoreInvalidChars)

Read the bytes encoded in a Base64 encoded String and provide them via an InputStream.

Parameters:

base64String - The String containing the Base64 encoded bytes.

ignoreInvalidChars - Whether to ignore invalid Base64 characters.

Returns:

The InputStream from which the binary content of the base64String can be read.

encode

public static String encode(byte[] bytes)
                     throws IOException

Convert a byte array to a Base64 encoded String.

Parameters:

bytes - The bytes to encode.

Returns:

String The Base64 encoded representation of the bytes.

Throws:

IOException - Failed to write the bytes as Base64 data.

encode

public static String encode(InputStream inputStream)
                     throws IOException

Convert the data contained in the given stream to a Base64 encoded String.

Parameters:

inputStream - The stream containing the data to encode.

Returns:

The Base64 encoded data of inputStream, as a String.

Throws:

IOException - Failed to convert the data in the stream.
