80+ .. function :: a2b_ascii85(string, /, *, fold_spaces=False, wrap=False, ignore=b"")
81+
82+ Convert Ascii85 data back to binary and return the binary data.
83+
84+ Valid Ascii85 data contains characters from the Ascii85 alphabet in groups
85+ of five (except for the final group, which may have from two to five
86+ characters). Each group encodes 32 bits of binary data in the range from
87+ ``0 `` to ``2 ** 32 - 1 ``, inclusive. The special character ``z `` is
88+ accepted as a short form of the group ``!!!!! ``, which encodes four
89+ consecutive null bytes.
90+
91+ If *fold_spaces * is true, the special character ``y `` is also accepted as a
92+ short form of the group ``+<VdL ``, which encodes four consecutive spaces.
93+ Note that neither short form is permitted if it occurs in the middle of
94+ another group.
95+
96+ If *wrap * is true, the input begins with ``<~ `` and ends with ``~> ``, as in
97+ the Adobe Ascii85 format.
98+
99+ *ignore * is an optional bytes-like object that specifies characters to
100+ ignore in the input.
101+
102+ Invalid Ascii85 data will raise :exc: `binascii.Error `.
103+
104+
105+ .. function :: b2a_ascii85(data, /, *, fold_spaces=False, wrap=False, width=0, pad=False)
106+
107+ Convert binary data to a formatted sequence of ASCII characters in Ascii85
108+ coding. The return value is the converted data.
109+
110+ If *fold_spaces * is true, four consecutive spaces are encoded as the
111+ special character ``y `` instead of the sequence ``+<VdL ``.
112+
113+ If *wrap * is true, the output begins with ``<~ `` and ends with ``~> ``, as
114+ in the Adobe Ascii85 format.
115+
116+ If *width * is provided and greater than 0, the output is split into lines
117+ of no more than the specified width separated by the ASCII newline
118+ character.
119+
120+ If *pad * is true, the input is padded to a multiple of 4 before encoding.
121+
122+
123+ .. function :: a2b_base85(string, /, *, strict_mode=False, z85=False)
124+
125+ Convert base85 data back to binary and return the binary data.
126+ More than one line may be passed at a time.
127+
128+ If *strict_mode * is true, only valid base85 data will be converted.
129+ Invalid base85 data will raise :exc: `binascii.Error `.
130+
131+ If *z85 * is true, the base85 data uses the Z85 alphabet.
132+ See `Z85 specification <https://rfc.zeromq.org/spec/32/ >`_ for more information.
133+
134+ Valid base85 data contains characters from the base85 alphabet in groups
135+ of five (except for the final group, which may have from two to five
136+ characters). Each group encodes 32 bits of binary data in the range from
137+ ``0 `` to ``2 ** 32 - 1 ``, inclusive.
138+
139+
140+ .. function :: b2a_base85(data, /, *, pad=False, newline=True, z85=False)
141+
142+ Convert binary data to a line of ASCII characters in base85 coding.
143+ The return value is the converted line.
144+
145+ If *pad * is true, the input is padded to a multiple of 4 before encoding.
146+
147+ If *newline * is true, a newline char is appended to the result.
148+
149+ If *z85 * is true, the Z85 alphabet is used for conversion.
