Functions

func GenerateOfficialDraftShareURL 

func GenerateOfficialDraftShareURL(dialconf *proxy.DialConf) string

https://p4gefau1t.github.io/trojan-go/developer/url/

func GetAddrFrom 

func GetAddrFrom(buf utils.ByteReader, ismux bool) (addr netLayer.Addr, err error)

依照trojan协议的格式读取 地址的域名、ip、port信息

func InitUsers added in v1.2.2 

func InitUsers(uc []utils.UserConf) (us []utils.User)

func PassBytesToStr added in v1.2.2 

func PassBytesToStr(bs []byte) string

28字节数据转56字节字符串

func PassStrToBytes added in v1.2.2 

func PassStrToBytes(str string) []byte

56字节数据转28字节字符串

func SHA224 

func SHA224(password string) (r [passBytesLen]byte)

即trojan 的 任意长度密码 的 定长二进制表示。

func SHA224_hexString 

func SHA224_hexString(password string) string

func SHA224_hexStringBytes 

func SHA224_hexStringBytes(password string) []byte

trojan协议 的前56字节 是 sha224的28字节 每字节 转义成 base 16, with lower-case letters for a-f 的 两个字符。 实际上trojan协议文档写的不严谨，它只说了用hex，没说用大写还是小写。我看它代码实现用的是小写。

func WriteAddrToBuf 

func WriteAddrToBuf(target netLayer.Addr, buf *bytes.Buffer)
