AN62(AlphaNumeric62)

BASE64 Encode에는 +/= 기본형 또는 -_= URL형이 있다.
여기서, 항상 특수문자가 문제가 되어. 0~9, A~Z, a~z만으로 이루어진 AlphaNumeric62을 만들어 보았다.

원리

Unicode값	UTF-8	Byte단위 값의 범위	비고
0x000000~0x00007F	0xxx xxxx	0x00~0x7F	ASCII
0x000080~0x0007FF	110x xxxx 10xx xxxx	0xC0~0xDF, 0x80~0xBF	유럽
0x000800~0x00FFFF	1110 xxxx 10xx xxxx 10xx xxxx	0xE0~0xEF, 0x80~0xBF	한글등
0x010000~0x10FFFF	1111 0zzz 10zz xxxx 10xx xxxx 10xx xxxx	0xF0~0xF4, 0x80~0xBF

그래서, 0x00~0x7F, 0x80~0xBF, 0xC0~0xDF, 0xE0~0xEF, 0xF0~0xF4 즉, 0x00~0xF4(245가지).

2453 < 624 (14,706,125 < 14,776,336) 이다. (즉, 245가지 3덩어리를 62가지 4덩어리로 표현가능하다.)

BASE64 Encode의 원리도 2563 = 644 즉, 2(8*3) = 2(6*4) 로 3Byte을 6bit씩 4덩어리로 표현한 것이다.

장단점

장점

특수문자(기호)가 없어 어떠한 환경에서 값으로 사용할 수 있음.

단점

BASE64는 bit연산으로 구현하고, AN62는 산술연산으로 다소 속도는 느림
Binary가 안 된다. ( 대안 : Base62 를 이용한다. )
