Base family: Base64, Base32 and Base16

In the code of Base64 http://xiaoqin00.blog.51cto.com/10468367/ 1713961, we say that the Base64 encoding is a 64 (2 6-square) ASCII character that represents 256 (2) ASCII characters, that is, 8-bit binary arrays are encoded into three-bit ASCII characters, the length is four higher than the original.

Similarly, the base32 is a 32 (2 of the 5-bit) of a specific ASCII code to represent 256 ASCII code. Therefore, 5 ASCII characters are BASE32 encoded and become 8 characters (Convention number 40), the length is increased by 3/5. Less than 8n with "=" Top up.

Base16 is the use of 16 (2 of the 4) of a specific ASCII code to represent 256 ASCII characters. 1 ASCII characters are BASE16 encoded and become 2 characters, increasing the length by a factor. Less than 2n with "=" complement

In the base family, there is Base64, and no 189 is base32,

The Base64 contains uppercase letters (A-Z), lowercase letters (A-Z), digital 0--9, and +/;

Base64 Index Table:

Only uppercase letters (A-Z) and numbers 234567 in Base32

Base16 only the number 0-9 and the uppercase letter abcdef.
