Classes

AuthenticationString

capitalize(...)

  B.capitalize() -> copy of B

  Return a copy of B with only its first character capitalized (ASCII)
  and the rest lower-cased.
center(self, width, fillchar=b' ', /)

  Return a centered string of length width.

  Padding is done using the specified fill character.
count(...)

  B.count(sub[, start[, end]]) -> int

  Return the number of non-overlapping occurrences of subsection sub in
  bytes B[start:end].  Optional arguments start and end are interpreted
  as in slice notation.
decode(self, /, encoding='utf-8', errors='strict')

  Decode the bytes using the codec registered for encoding.

    encoding
      The encoding with which to decode the bytes.
    errors
      The error handling scheme to use for the handling of decoding errors.
      The default is 'strict' meaning that decoding errors raise a
      UnicodeDecodeError. Other possible values are 'ignore' and 'replace'
      as well as any other name registered with codecs.register_error that
      can handle UnicodeDecodeErrors.
endswith(...)

  B.endswith(suffix[, start[, end]]) -> bool

  Return True if B ends with the specified suffix, False otherwise.
  With optional start, test B beginning at that position.
  With optional end, stop comparing B at that position.
  suffix can also be a tuple of bytes to try.
expandtabs(self, /, tabsize=8)

  Return a copy where all tab characters are expanded using spaces.

  If tabsize is not given, a tab size of 8 characters is assumed.
find(...)

  B.find(sub[, start[, end]]) -> int

  Return the lowest index in B where subsection sub is found,
  such that sub is contained within B[start,end].  Optional
  arguments start and end are interpreted as in slice notation.

  Return -1 on failure.
fromhex(string, /)

  Create a bytes object from a string of hexadecimal numbers.

  Spaces between two numbers are accepted.

hex(...)

  Create a string of hexadecimal numbers from a bytes object.

    sep
      An optional single character or byte to separate hex bytes.
    bytes_per_sep
      How many bytes between separators.  Positive values count from the
      right, negative values count from the left.

  Example:
  >>> value = b'\xb9\x01\xef'
  >>> value.hex()
  'b901ef'
  >>> value.hex(':')
  'b9:01:ef'
  >>> value.hex(':', 2)

  >>> value.hex(':', -2)
  'b901:ef'

  characters and lowercase characters only cased ones. Return False
  otherwise.

partition(self, sep, /)

  Partition the bytes into three parts using the given separator.

  This will search for the separator sep in the bytes. If the separator is found,
  returns a 3-tuple containing the part before the separator, the separator

  If the separator is not found, returns a 3-tuple containing the original bytes
  object and two empty bytes objects.

  Padding is done using the specified fill character.
rpartition(self, sep, /)

  Partition the bytes into three parts using the given separator.

  This will search for the separator sep in the bytes, starting at the end. If
  the separator is found, returns a 3-tuple containing the part before the
  separator, the separator itself, and the part after it.

  If the separator is not found, returns a 3-tuple containing two empty bytes
  objects and the original bytes object.
