What is Base64?

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.

For example:

For text "base64", the base64 encoded string is "YmFzZTY0", the conversion is shown by the following table:

Text content	b								a								s								e								6								4
ASCII	98 (0x62)								97 (0x61)								115 (0x73)								101 (0x65)								54 (0x36)								52 (0x34)
Bit pattern	0	1	1	0	0	0	1	0	0	1	1	0	0	0	0	1	0	1	1	1	0	0	1	1	0	1	1	0	0	1	0	1	0	0	1	1	0	1	1	0	0	0	1	1	0	1	0	0
Index	24						38						5						51						25						19						24						52
Base64-encoded	Y						m						F						z						Z						T						Y						0
