    Uses "The Base64 Alphabet" as specified in Table 1 of + * RFC 4648 and RFC 2045 for encoding and decoding operation. + * The encoder does not add any line feed (line separator) + * character. The decoder rejects data that contains characters + * outside the base64 alphabet.

    Uses the "URL and Filename safe Base64 Alphabet" as specified + * in Table 2 of RFC 4648 for encoding and decoding. The + * encoder does not add any line feed (line separator) character. + * The decoder rejects data that contains characters outside the + * base64 alphabet.

    • + * + *
  • MIME + *

    Uses the "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 {@code '\r'} followed immediately by + * a linefeed {@code '\n'} as the line separator. No line separator + * is added to the end of the encoded output. All line separators + * or other characters not found in the base64 alphabet table are + * ignored in decoding operation.
