-Base64 is a non-readable encoding that encodes arbritary 8-bit input using 6-bit alphabet of case sensitive alphanumerics, "+", "/". Every 3 bytes of input map to 4 bytes of output. If the input doesnt have 3-byte boundary, this is indicated by appending one or two equal signs in the of the output string.
