-5. Base 32 Encoding
-
- The Base 32 encoding is designed to represent arbitrary sequences of
- octets in a form that needs to be case insensitive but need not be
- humanly readable.
-
- A 33-character subset of US-ASCII is used, enabling 5 bits to be
- represented per printable character. (The extra 33rd character, "=",
- is used to signify a special processing function.)
-
- The encoding process represents 40-bit groups of input bits as output
- strings of 8 encoded characters. Proceeding from left to right, a
- 40-bit input group is formed by concatenating 5 8bit input groups.
- These 40 bits are then treated as 8 concatenated 5-bit groups, each
- of which is translated into a single digit in the base 32 alphabet.
- When encoding a bit stream via the base 32 encoding, the bit stream
- must be presumed to be ordered with the most-significant-bit first.
- That is, the first bit in the stream will be the high-order bit in
- the first 8bit byte, and the eighth bit will be the low-order bit in
- the first 8bit byte, and so on.
-
- Each 5-bit group is used as an index into an array of 32 printable
- characters. The character referenced by the index is placed in the
- output string. These characters, identified in Table 3, below, are
- selected from US-ASCII digits and uppercase letters.
-

-
-
- Special processing is performed if fewer than 40 bits are available
- at the end of the data being encoded. A full encoding quantum is
- always completed at the end of a body. When fewer than 40 input bits
- are available in an input group, zero bits are added (on the right)
- to form an integral number of 5-bit groups. Padding at the end of
- the data is performed using the "=" character. Since all base 32
- input is an integral number of octets, only the following cases can
- arise:
-
- (1) the final quantum of encoding input is an integral multiple of 40
- bits; here, the final unit of encoded output will be an integral
- multiple of 8 characters with no "=" padding,
-
- (2) the final quantum of encoding input is exactly 8 bits; here, the
- final unit of encoded output will be two characters followed by six
- "=" padding characters,
-
- (3) the final quantum of encoding input is exactly 16 bits; here, the
- final unit of encoded output will be four characters followed by four
- "=" padding characters,
-
- (4) the final quantum of encoding input is exactly 24 bits; here, the
- final unit of encoded output will be five characters followed by
- three "=" padding characters, or
-
- (5) the final quantum of encoding input is exactly 32 bits; here, the
- final unit of encoded output will be seven characters followed by one
- "=" padding character.
-
-
-6. Base 32 Encoding with Extended Hex Alphabet
-
- The following description of base 32 is due to [7]. This encoding
- should not be regarded as the same as the "base32" encoding, and
- should not be referred to as only "base32".
-
- One property with this alphabet, that the base64 and base32 alphabet
- lack, is that encoded data maintain its sort order when the encoded
- data is compared bit-wise.
-
- This encoding is identical to the previous one, except for the
- alphabet. The new alphabet is found in table 4.
