Class Base64

java.lang.Object

pro.fessional.mirana.bits.Base64

public class Base64
extends Object

 RFC4648_URLSAFE, UTF8 and no pad by default.

 This array is a lookup table that translates 6-bit positive integer
 index values into their "Base64 Alphabet" equivalents as specified
 in "Table 1: The Base64 Alphabet" of RFC 2045 (and RFC 4648).
 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M',
 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z',
 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm',
 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z',
 '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '+', '/'

 It's the lookup table for "URL and Filename safe Base64" as specified
 in Table 2 of the RFC 4648, with the '+' and '/' changed to '-' and
 '_'. This table is used when BASE64_URL is specified.
 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M',
 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z',
 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm',
 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z',
 '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '-', '_'
