hasparse's Introduction

hasparse

用于解析 以Hasclient-Hasserver方式进行 Kerberos 认证中编码为 BER 情况的工具类,只实现了 EncryptedData.Cipher 以 Aes128 加密情况。 涉及票据的获取、BER 解码、Aes128解码等

入口类:
func HasKdc(userName, password, authSeverAddr, port string) *assign.KdcRep

KdcRep 结构如下, EncPart 是解密后最终的结果

type KdcRep struct {
	Pvno        int
	MsgType     int
	Padata      *PAData //optional
	Crealm      string
	Cname       *PrincipalName
	Ticket      *KdcTicket
	EncData     *EncryptedData
	fieldInfos  []int
	position    []byte 
	taggingList *list.List
	EncPart     *EncKdcRepPart
}

TODO

  • kdcRep解析改成EncPart方式
  • 部分条件例外分支尚未实现
  • Aes128解码中未进行 checksum 校验

concat

申明:个人能力有限,时间有限,通用性上不够完善
