2 :mod:`binascii` --- Convert between binary and ASCII
6 :synopsis: Tools for converting between binary and various ASCII-encoded binary
16 binary and various ASCII-encoded binary representations. Normally, you will not
19 low-level functions written in C for greater speed that are used by the
20 higher-level modules.
27 Convert a single line of uuencoded data back to binary and return the binary
28 data. Lines normally contain 45 (binary) bytes, except for the last line. Line
34 Convert binary data to a line of ASCII characters, the return value is the
41 Convert a block of base64 data back to binary and return the binary data. More
47 Convert binary data to a line of ASCII characters in base64 coding. The return
51 MIME-base64 standard. Otherwise the output conforms to :rfc:`3548`.
56 Convert a block of quoted-printable data back to binary and return the binary
63 Convert binary data to a line(s) of ASCII characters in quoted-printable
70 encoded as well; otherwise linefeed conversion might corrupt the binary data
76 Convert binhex4 formatted ASCII data to binary, without doing RLE-decompression.
77 The string should contain a complete number of binary bytes, or (in case of the
83 Perform RLE-decompression on the data, as per the binhex4 standard. The
92 Perform binhex4 style RLE-compression on *data* and return the result.
97 Perform hexbin4 binary-to-ASCII translation and return the resulting string. The
98 argument should already be RLE-coded, and have a length divisible by 3 (except
110 Compute CRC-32, the 32-bit checksum of data, starting with an initial crc. This

125 return value is the correct 32bit binary representation
129 The return value is in the range [-2**31, 2**31-1]
135 The return value is unsigned and in the range [0, 2**32-1]
142 Return the hexadecimal representation of the binary *data*. Every byte of
143 *data* is converted into the corresponding 2-digit hex representation. The
150 Return the binary data represented by the hexadecimal string *hexstr*. This
