July 21, 2026 - Returns an input stream for decoding Base64 encoded byte stream. The read methods of the returned InputStream will throw IOException when reading bytes that cannot be decoded. Closing the returned input stream will close the underlying input stream. ... Java™ Platform Standard Ed.

February 18, 2026 - Java supports Base64 encoding and decoding features through the java.util.Base64 utility class.

March 15, 2022 - Base64 encoding and decoding capabilities were added in java8 via the java.util.Base64 utility class.

January 20, 2026 - Uses "The Base64 Alphabet" as specified in Table 1 of RFC 2045 for encoding and decoding operation. The encoded output must be represented in lines of no more than 76 characters each and uses a carriage return '\r' followed immediately by a linefeed '\n' as the line separator.

Decodes all bytes from the input byte buffer using the Base64 encoding scheme, writing the results into a newly-allocated ByteBuffer.

December 6, 2017 - By replacing + with - and / with _, URL and Filename Safe obviates the need for URL encoders/decoders (and their impacts on the lengths of encoded values). Also, this variant is useful when the encoded data is to be used for a filename because Unix and Windows filenames cannot contain /. Java 8 introduced a Base64 API consisting of the java.util.Base64 class along with its Encoder and Decoder nested static classes.

June 28, 2024 - Java: The Base64 class in java.util provides methods for decoding.

January 20, 2026 - 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. No bytes will be written to the output byte array if the output byte array is not big enough. If the input byte array is not in valid Base64 encoding scheme then some bytes may have been written to the output byte array before IllegalargumentException is thrown.

This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045.

April 9, 2026 - The basic decoder rejects anything outside the Base64 alphabet — and that includes the \r\n line breaks that MIME-encoded content always contains. Email attachments, PEM certificates, and some older API responses wrap Base64 output at 76 ...
