本文介绍了一种将SHA哈希转换为更紧凑、更易读的BASE30表示的算法，并通过特定步骤生成激活码。该过程包括哈希请求代码和许可ID，然后使用SHA算法进行哈希，再将哈希结果转换为BASE30格式，并加入额外的处理以生成最终的激活码。

""" converts a "number" between two bases of arbitrary digits

The input number is assumed to be a string of digits from the
fromdigits string (which is in order of smallest to largest
digit). The return value is a string of elements from todigits
(ordered in the same way). The input and output bases are
determined from the lengths of the digit strings. Negative
signs are passed through.

decimal to binary
>>> baseconvert(555,BASE10,BASE2)
'1000101011'

binary to decimal
>>> baseconvert('1000101011',BASE2,BASE10)
'555'

integer interpreted as binary and converted to decimal (!)
>>> baseconvert(1000101011,BASE2,BASE10)
'555'

base10 to base4
>>> baseconvert(99,BASE10,"0123")
'1203'

base4 to base5 (with alphabetic digits)
>>> baseconvert(1203,"0123","abcde")
'dee'

base5, alpha digits back to base 10
>>> baseconvert('dee',"abcde",BASE10)
'99'

decimal to a base that uses A-Z0-9a-z for its digits
>>> baseconvert(257938572394L,BASE10,BASE62)
'E78Lxik'

..convert back
>>> baseconvert('E78Lxik',BASE62,BASE10)
'257938572394'

binary to a base with words for digits (the function cannot convert this back)
>>> baseconvert('1101',BASE2,('Zero','One'))
'OneOneZeroOne'
