binary/ASCII conversions
binascii – binary/ASCII conversions
This module implements a subset of the corresponding CPython module, as described below. For more information, refer to the original CPython documentation: binascii.
This module implements conversions between binary data and various encodings of it in ASCII form (in both directions).
Functions
binascii.hexlify
binascii.hexlify(data, [sep])Convert the bytes in the data object to a hexadecimal representation. Returns a bytes object.
If the additional argument sep is supplied it is used as a separator between hexadecimal values.
binascii.unhexlify
binascii.unhexlify(data)Convert hexadecimal data to binary representation. Returns bytes string. (i.e. inverse of hexlify)
binascii.a2b_base64
binascii.a2b_base64(data)Decode base64-encoded data, ignoring invalid characters in the input. Conforms to RFC 2045 s.6.8. Returns a bytes object.
binascii.b2a_base64
binascii.b2a_base64(data, *, newline=True)Encode binary data in base64 format, as in RFC 3548. Returns the encoded data followed by a newline character if newline is true, as a bytes object.
