It is the responsibility of the invoker of this method to make sure the output byte array dst has enough space for decoding all bytes from the input byte array. So I used following code. So if the final unit of the encoded byte data only has two or three Base64 characters (without the corresponding This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045. Decoder getDecoder() Returns a Base64. Not having programmed Java for a while I am probably not using the most efficient method, however I managed to implement a function working 99% correctly. decodeBase64(stringBase64); // Note the try-with-resources block here, to close the stream automatically try (OutputStream stream = new Decodes all bytes from the input byte array using the Base64 encoding scheme, writing the results into the given output byte array, starting at offset 0. . p7b file. such as the name of the class Year is Java 8 thêm lớp mới java.
