UnsupportedEncodingException import java. The decoder ignores all line separators and other characters not found in the basic base64 alphabet. The base64 encoding is adapted from RFC 1113, with one. Each line (except the last line) is separated from the next line via a carriage return (\r) followed by a linefeed (\n). This encoding is based on the one used in Privacy Enhanced Mail applications, as defined in RFC 1113. The encoded output is organized into lines of no more than 76 characters. MIME enforces a limit on line length of Base64 encoded data. MIME: The MIME variant uses the Basic Base64 alphabet ( A-Za-z0-9 /). The decoder rejects data that contains characters outside A-Za-z0-9-_. URL and Filename Safe: It is same as the Basic Base64 encoding except that is replaced by - and / is replaced by _ to make the output URL and filename safe. The decoder rejects data that contains characters outside this set. Its used for example in the Basic authorization scheme. The algorithm converts the input to a set of characters containing A-Z, a-z, 0-9, and /. This method encodes the given string using the base64 encoding specified in RFC-2045 (Section 6.8). Basic: This is the standard Base64 encoding defined in the RFC 4648.Java 8’s Base64 API contains implementations for all the Base64 encoding and decoding variants described in the official RFC 4648.įollowing variants of Base64 encoding and decoding is supported. In this article, you’ll learn how to Base64 decode any Base64 encoded text back to binary data.
