If not specified, one will be autogenerated (this is recommended). If specified, it must be 20 hexadecimal characters. :type relaxed: bool :param relaxed: By default, providing an invalid value for one of the other keywords will result in a :exc:`ValueError`. If ``relaxed=True``, and the error can be corrected, a :exc:`~passlib.exc.PasslibHashWarning` will be issued instead. Correctable errors include ``salt`` strings that are too long. .. versionadded:: 1.6 )salt(z/^S:(?P[0-9a-f]{40})(?P[0-9a-f]{20})$cCsHt|dd}|j|}|stj||dd\}}|||dS)Nr%rr:chk)r:checksum)r _hash_regexmatchr4excInvalidHashErrorgroupr)r rmr:r=rrr from_strings   zoracle11.from_stringcCs(|j}td||jf}t|S)NzS:%s%s)r>rrr:r )r+r=rrrr to_stringszoracle11.to_stringcCs<t|tr |d}t|t|jd}t|S)Nr"r%) r&r r)rrr: hexdigestr r)r+r,r=rrrr.s   zoracle11._calc_checksumN)r/r0r1r2r3 setting_kwdsr7r4UPPER_HEX_CHARSr6 min_salt_size max_salt_size salt_charsrecompilerIr?r8rErFr.rrrrr9hs  r9)rr)#r2binasciirrhashlibrrMlogging getLoggerr/log passlib.utilsrrpasslib.utils.compatrrr r r passlib.crypto.desr passlib.utils.handlersutilshandlersr4__all__rr*HasUserContext StaticHandlerrHasSaltGenericHandlerr9rrrrs    4
