  base64decode,
  bytes2hex,

} from 'x-byte-js'

// encode base64 in standard mode
// output: aGVsbG8g5L2g5aW9IOKcjO+4jw==
base64('hello 你好 ✌️')

// encode base64 in url safe mode
// output: aGVsbG8g5L2g5aW9IOKcjO-4jw

// encode base64 in url safe mode with padding
// output: aGVsbG8g5L2g5aW9IOKcjO-4jw==

// decode base64 strings (supporting both standard mode and URL safe mode).
// output: hello 你好 ✌️
