/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
|
||||||
|
The following encoding technique is taken from RFC 1521 by Borenstein
|
||||||
|
and Freed. It is reproduced here in a slightly edited form for
|
||||||
|
convenience.
|
||||||
|
|
||||||
|
A 65-character subset of US-ASCII is used, enabling 6 bits to be
|
||||||
|
represented per printable character. (The extra 65th character, "=",
|
||||||
|
is used to signify a special processing function.)
|
||||||
|
|
||||||
|
The encoding process represents 24-bit groups of input bits as output
|
||||||
|
strings of 4 encoded characters. Proceeding from left to right, a
|
||||||
|
24-bit input group is formed by concatenating 3 8-bit input groups.
|
||||||
|
These 24 bits are then treated as 4 concatenated 6-bit groups, each
|
||||||
|
of which is translated into a single digit in the base64 alphabet.
|
||||||
|
|
||||||
|
Each 6-bit group is used as an index into an array of 64 printable
|
||||||
|
characters. The character referenced by the index is placed in the
|
||||||
|
output string.

||||||

|
||||||
|
Special processing is performed if fewer than 24 bits are available
|
||||||
|
at the end of the data being encoded. A full encoding quantum is
|
||||||
|
always completed at the end of a quantity. When fewer than 24 input
|
||||||
|
bits are available in an input group, zero bits are added (on the
|
||||||
|
right) to form an integral number of 6-bit groups. Padding at the
|
||||||
|
end of the data is performed using the '=' character.
|
||||||
|
|
||||||
|
Since all base64 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 24 bits; here, the final unit of encoded
|
||||||
|
output will be an integral multiple of 4 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 two "=" padding characters, or
|
||||||
|
(3) the final quantum of encoding input is exactly 16 bits;
|
||||||
|
here, the final unit of encoded output will be three
|
||||||
|
characters followed by one "=" padding character.

.Sh DESCRIPTION
|
||||||
|
.Nm
|
||||||
|
provides functions for base64 encoding and decoding. The
|
||||||
|
.Nm base64_encode
|
||||||
|
function takes arbtitrary binary data and a pre-allocated buffer to
|
||||||
|
store the base64-encoded data in. The expected size of the buffer
|
||||||
|
(sans a NULL byte) can be retrieved with the function
|
||||||
|
.Nm base64_enclen .
|
||||||
|
The destination size should be the value of
|
||||||
|
.Nm base64_enclen(buflen)
|
||||||
|
plus an extra NULL byte.
|
||||||
|
.Nm base64_decode
|
||||||
|
reverses the process; the length to the base64-encoded buffer is not
|
||||||
|
required. The size of the destination buffer should be at least
|
||||||
|
.Nm base64_declen(b64buflen) + 1 .
|
||||||
|
The current version of the library can be retrieved with the
|
||||||
|
.Nm base64_lib_version
|
||||||
|
returns the current version string for the package.
|
||||||
|
.Sh RETURN VALUES
|
||||||
|
.Nm base64_encode
|
||||||
|
and
|
||||||
|
.Nm base64_decode
|
||||||
|
return -1 on error, or the length of the stored data on success.
|
||||||
|
.Nm base64_enclen
|
||||||
|
returns the base64-encoded length of a base64-encoded buffer with a
|
||||||
|
source buffer length of
|
||||||
|
.Nm len ;
|
||||||
|
.Nm base64_decode
|
||||||
|
returns the maximum base64-decoded size of a source buffer of length
|
||||||
|
.Nm len ,
|
||||||
|
possibly two more bytes than actually required. The actual length of
|
||||||
|
the buffer depends on the encoded data.
|
||||||
|
.Nm base64_lib_version
|
||||||
|
returns a pointer to a statically allocated buffer containing the
|
||||||
|
version number. This pointer should not be freed.
|
||||||
|
.Sh EXAMPLES
|
||||||
|
A sample section of code doing base64 encoding might look like:
|
||||||
|
.Bd -literal
|
||||||
|
uint8_t msg[] = "Hello, world.";
|
||||||
|
char *b64 = NULL;
|
||||||
|
size_t b64len;
|
||||||
|
|
||||||
|
b64len = base64_enclen(strlen(msg));
|
||||||
|
b64 = malloc(b64len + 1);
|
||||||
|
if (NULL == b64)
|
||||||
|
return -1;
|
||||||
|
memset(b64, 0x0, b64len);
|
||||||
|
|
||||||
|
if (base64_encode(b64, b64len + 1, msg, strlen(msg)) != -1);
|
||||||
|
do_something(b64, b64len);
|
||||||
|
free(b64);
|
||||||
|
.Ed
|
||||||
|
Decoding is similar:
|
||||||
|
.Bd -literal
|
||||||
|
char msg[] = "SGVsbG8sIHdvcmxk";
|
||||||
|
uint8_t *buf = NULL;
|
||||||
|
size_t buflen;
|
||||||
|
|
||||||
|
buflen = base64_declen(strlen(msg));
|
||||||
|
buf = malloc(buflen + 1);
|
||||||
|
if (NULL == buf)
|
||||||
|
return -1;
|
||||||
|
memset(buf, 0x0, buflen + 1);
|
||||||
|
|
||||||
|
if (base64_decode(msg, buf, buflen) != -1)
|
||||||
|
do_something(buf, buflen);
|
||||||
|
free(buf);
|
||||||
|
.Ed
|
||||||
|
.Sh ERRORS
|
||||||
|
The most common cause for failure will be an incorrectly-sized buffer,
|
||||||
|
or an invalid base64-encoded string.
|
||||||
|
.Sh STANDARDS
|
||||||
|
.Nm
|
||||||
|
conforms to C99 and SUSv4.
