Wikipedia: Base64
The base64 module encodes and decodes using standard, URL-safe, and raw (no padding) variants. Input and output are bytes.
fmt := import("fmt")
base64 := import("base64")msg := bytes("Hello, Tengo!")
enc := base64.encode(msg)
fmt.println(string(enc))dec := base64.decode(enc)
fmt.println(string(dec))url_enc := base64.url_encode(bytes("data?key=value&x=1"))
fmt.println(string(url_enc))
fmt.println(string(base64.url_decode(url_enc)))raw := base64.raw_encode(bytes("Tengo"))
fmt.println(string(raw))try it
