Base32 is one of several base 32 transfer encodings using a 32-character subset of the twenty-six letters A–Z and ten digits 0–9. Its closest encoding relation is Base30 that is used by the Natural Area Code. Primarily Base32 is used to encode binary data, but is able to encode binary text like ASCII. == Software == Base32 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers. Base32 consists of a symbol set made up of 32 different characters, as well as an algorithm for encoding arbitrary sequences of 8-bit bytes into the Base32 alphabet. Because more than one 5-bit Base32 symbol is needed to represent each 8-bit input byte, it also specifies requirements on the allowed lengths of Base32 strings (which must be multiples of 40 bits). The closely related Base64 system, in contrast, uses a set of 64 symbols. Base32 implementations in C/C++,〔http://sourceforge.net/projects/cyoencode/〕 Perl,〔http://search.cpan.org/dist/MIME-Base32/Base32.pm〕 Python〔https://docs.python.org/2/library/base64.html〕 are available. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Base32」の詳細全文を読む スポンサード リンク
