base64.b85encode(b, pad=False) Encode the bytes-like object b using base85 (as used in e.g. git-style binary diffs) and return the encoded bytes. If pad is true, the input is padded with b'\0' so its length is a multiple of 4 bytes before encoding. New in version 3.4.

base64.decode(input, output) Decode the contents of the binary input file and write the resulting binary data to the output file. input and output must be file objects. input will be read until input.readline() returns an empty bytes object.

base64.b64decode(s, altchars=None, validate=False) Decode the Base64 encoded bytes-like object or ASCII string s and return the decoded bytes. Optional altchars must be a bytes-like object or ASCII string of at least length 2 (additional characters are ignored) which specifies the alternative alphabet used instead of the + and / characters. A binascii.Error exception is raised if s is incorrectly padded. If validate is False (the default), characters that are neither in the normal base-64 al

base64.b85decode(b) Decode the base85-encoded bytes-like object or ASCII string b and return the decoded bytes. Padding is implicitly removed, if necessary. New in version 3.4.

base64.b32encode(s) Encode the bytes-like object s using Base32 and return the encoded bytes.

base64.b64encode(s, altchars=None) Encode the bytes-like object s using Base64 and return the encoded bytes. Optional altchars must be a bytes-like object of at least length 2 (additional characters are ignored) which specifies an alternative alphabet for the + and / characters. This allows an application to e.g. generate URL or filesystem safe Base64 strings. The default is None, for which the standard Base64 alphabet is used.

base64.a85encode(b, *, foldspaces=False, wrapcol=0, pad=False, adobe=False) Encode the bytes-like object b using Ascii85 and return the encoded bytes. foldspaces is an optional flag that uses the special short sequence ‘y’ instead of 4 consecutive spaces (ASCII 0x20) as supported by ‘btoa’. This feature is not supported by the “standard” Ascii85 encoding. wrapcol controls whether the output should have newline (b'\n') characters added to it. If this is non-zero, each output line will be at m

base64.b16encode(s) Encode the bytes-like object s using Base16 and return the encoded bytes.

base64.b16decode(s, casefold=False) Decode the Base16 encoded bytes-like object or ASCII string s and return the decoded bytes. Optional casefold is a flag specifying whether a lowercase alphabet is acceptable as input. For security purposes, the default is False. A binascii.Error is raised if s is incorrectly padded or if there are non-alphabet characters present in the input.

base64.b32decode(s, casefold=False, map01=None) Decode the Base32 encoded bytes-like object or ASCII string s and return the decoded bytes. Optional casefold is a flag specifying whether a lowercase alphabet is acceptable as input. For security purposes, the default is False. RFC 3548 allows for optional mapping of the digit 0 (zero) to the letter O (oh), and for optional mapping of the digit 1 (one) to either the letter I (eye) or letter L (el). The optional argument map01 when not None, sp
