A binascii.Error is raised if the input is incorrectly padded or if there are non-alphabet characters present in the input. a 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, specifies which letter the digit 1 should be mapped to (when map01 is not None, the digit 0 is always mapped to the letter O). For security purposes the default is None, so that 0 and 1 are not allowed in the input. s ABCDEFGHIJKLMNOPQRSTUVWXYZ234567s 0123456789ABCDEFGHIJKLMNOPQRSTUVcsR|tvrdd|DfddDt|<dt|ts#t|}t|d}|r3|dd|}t}tj}t|}t dt|dD]+}||||dd}|||d?||d ?d @||d ?d @||d @7}qE|d krd |dd<t |S|dkrd|dd<t |S|dkrd|dd<t |S|dkrd|dd<t |S)NcSg|]}t|fqSr#r+.0ir#r#r$ z_b32encode..csg|] }D]}||qqSr#r#rFar>Zb32tabr#r$rHrbigi s======ir/s====s====) _b32tab2rrrrr3 bytearrayint from_bytesranger+)alphabetr"leftoverr.r^Zb32tab2rGcr#rLr$ _b32encodesB         rcc Cst|tvrddt|Dt|<t|}t|drtd|dur1t|}|tdd|}|r7| }t|}| d}|t|}t }t|}t dt|dD]1}|||d} d} z| D] } | d >|| } qdWn t y}td dw|| d d 7}qU|ds|d vrtd|r|r| d |K} | d d } d d |d} | d| |dd<t|S)NcSsi|]\}}||qSr#r#)rFkvr#r#r$ rIz_b32decode..zIncorrect paddings01OrYrrNzNon-base32 digit foundrP>rrTrVrX+)_b32rev enumerater%r3r(r6r*r+r,upperrstripr\r_KeyErrorto_bytes)r`r"casefoldmap01lZpadcharsdecodedZb32revrGZquantaaccrbZlastrar#r#r$ _b32decodesD         rwcC tt|SN)rc _b32alphabetr!r#r#r$r rZbase32)encodingcCstt|||Sry)rwrz)r"rrrsr#r#r$r sr )r|Z extra_argscCrxry)rc_b32hexalphabetr!r#r#r$r r{r Z base32hexcCs tt||Sry)rwr}r"rrr#r#r$r #s r cCst|S)zKEncode the bytes-like object s using Base16 and return a bytes object. )r(Zhexlifyrnr!r#r#r$r -sr cCs4t|}|r |}td|rtdt|S)aDecode the Base16 encoded bytes-like object or ASCII string s.
