Also, to make it easier to share base64 data, you can cut the output into multiple parts of the specified length. This series of bytes is then fed to base64 encoding algorithm that produces the base64 output. We support UTF8, UTF16, UTF32, UCS2, and UCS4 encoding formats, as well as Big Endian and Little Endian byte order formats for the multi-byte formats (UTF16, UCS2, UTF32, and UCS4). Base64 encoding converts the binary data into text format, which is passed through communication channel where a user can handle. First, as Unicode can be stored in computer memory in many different ways, it's encoded to bytes in the encoding format that you have chosen. Encoding your Unicode data to base64 is a two-step process. If only one or two bytes are encoded, then the "=" sign is used as the fill character at the end so that there were 4 characters in the output. In base64, every 3 bytes of data are encoded as 4 characters. The information encoded in base64 is represented by a set of bytes using 52 Latin characters and 10 numbers – A-Z, a-z, 0-9, and 2 additional symbols – "/" and "=". SELECT Base64Encode(0xA9) as 'Encoded © symbol' Here is the result set. In the following example, simple varbinary is base64 encoded. It lets you share your data on systems that don't understand Unicode. If urlsafe is true, the base64url string that is generated is incompatible with SQL Server's XML and JSON base64 decoders. The source can be a string or a connection, the output is either a raw vector ( outputNULL ) or. Base64 is a data encoding standard that uses only 64 ASCII symbols. base64decode decodes a base64-encoded string into binary data. The end of s can consist of zero, one, or two padding characters.This utility converts your Unicode letters, numbers, symbols, emojis, and other characters to base64 encoding. The valueless character, "=", is used for trailing padding. Base64 is used to encode binary files such as images within scripts, to avoid depending on external files. An arbitrary number of white-space characters can appear in s because all white-space characters are ignored. Base64 is also used when communicating with government Fiscal Signature printing devices (usually, over serial or parallel ports) to minimize the delay when transferring receipt characters for signing. The white-space characters, and their Unicode names and hexadecimal code points, are tab (CHARACTER TABULATION, U+0009), newline (LINE FEED, U+000A), carriage return (CARRIAGE RETURN, U+000D), and blank (SPACE, U+0020). Enter a character string in the input area on the left and click the encode button to encode the character string into data expressed in Base64 format. The base-64 digits in ascending order from zero are the uppercase characters "A" to "Z", lowercase characters "a" to "z", numerals "0" to "9", and the symbols "+" and "/". S is composed of base-64 digits, white-space characters, and trailing padding characters. The following example uses the ToBase64String(Byte) method to convert a byte array to a UUencoded (base-64) string, and then calls the FromBase64String(String) method to restore the original byte array. s contains a non-base-64 character, more than two padding characters, or a non-white space-character among the padding characters. The length of s, ignoring white-space characters, is not zero or a multiple of 4.
