Welcome to the home of the Web Sign project, more commonly referred to as WSign.

Web Sign is the Single Sign On applications for web applications .

Web Sign Based on browser cookie and http post

Web Sign简称为WSign,是一款基于浏览器Cookie和http post的Web应用单点登录系统.

WSign采用流行的加密和签名的技术保障单点登录的安全性.

An open and well-documented/开放具有良好文档

Protocol

Cookie Based Token(wc),Token transmit by browser cookie /基于Cookie认证，通过浏览器Cookie传递Token
Token Based Token(wt),Post token to target via http post method/通过HTTP POST的方式提交Token到目标应用

Token

1)Original Token 原始格式

[登录用户名]@@[Token过期时间(UTC)]
[login username]@@[Token expire date time(UTC)]

wsignuser@@2015-04-24T16:56:32.402+08:00

2)Encryption,then to HEX ,algorithm support DES,DESede,Blowfish and AES 加密格式，加密处理完成后，转换为HEX格式，加密方法DES,DESede,Blowfish and AES

3)Base64URL Token 编码格式Base64URL

Key Format 证书格式：JSON Web Key (JWK) 参见源代码 src/keystore.jwks,含公钥和私钥,WebRoot/key/jwk仅含公钥

Signature Algorithms 签名方法: JSON Web Algorithms (JWA)

 RS256        | RSASSA-PKCS-v1_5 using SHA-256    | Recommended    |

5)Transmit Token传递数据

Format [Base64URL Token].[Signature] or [Base64URL Token].
格式：[Base64URL编码].[签名] or [Base64URL编码].

备注：第2步和第4步为备选，建议同时使用

MEM: step 2 and step 4 is option,but Recommended

Token Name[Token名称]

WSign_Token

Token Parse[Token解析]

1)Token split 签名分离
    "."before is Token，after is Signature
    "."前半部分为Token数据，后半部分为签名
2)Validate Signature 验证签名
    
3)Decode Base64URL Token Base64URL Token解码
    
4)Decode encrypted Token 解密加密Token数据
    
5)Parse username & authentication time(UTC format) 解析用户名和Token过期时间(UTC)
    
6)Validate authentication time(UTC format) 验证Token认证时间
    if after now,valid，else invalid 
    大于当前时间,正确;小于当前时间,失效

备注:如果未签名，省略第2步;若果未加密省略第4步

MEM :if not Signature,skip step 2; if not Encryption skip step 4
