ubinascii – Binary / ASCII conversion

This module implements the corresponding CPython A subset of modules, as follows. See CPython document for details: binascii

This module realizes the conversion (bidirectional) between binary data and various ASCII codes.

Function

ubinascii.hexlify(data[, sep])

Converts a string to a hexadecimal representation.

differences with CPython

If additional parameter SEP is provided, It will be used as a separator in-between these hexadecimal values.

Without SEP parameter:

>>> ubinascii.hexlify('\x11\x22123')
b'1122313233'
>>> ubinascii.hexlify('abcdfg')
b'616263646667'

If the second parameter SEP is specified, it will be used to separate two hexadecimal numbers:

>>> ubinascii.hexlify('\x11\x22123', ' ')
b'11 22 31 32 33'
>>> ubinascii.hexlify('\x11\x22123', ',')
b'11,22,31,32,33'

ubinascii.unhexlify(data)

Convert hexadecimal string to binary string, the function is opposite to hexlify.

Example:

>>> ubinascii.unhexlify('313233')
b'123'

ubinascii.a2b_base64(data)

ecode Base64 encoded data, ignoring invalid characters in input. According with RFC 2045 s.6.8 。returns a bytes object。

ubinascii.b2a_base64(data)

Encoding binary data in Base64 format, as mentioned in RFC 3548 . Returns the encoded data, followed by a line break, as the bytes object.
