LtpaDecoder (Bropen Toolkit 4.8.1 API)

bropen.toolkit.utils.security.LtpaDecoder

LTPA Key 解码器，用于和 IBM 产品做 SSO 集成

示例：String tokenCipher = "1eDYcavQCLHppG9P6MHRADcy/igN1W+NbsPULYoFvtlbxET8FrOmSMcDuv+sG8ko6aRvT+jB0QA3Mv4oDdVvjW7D1C2KBb7Zjn32Ii/2xM36H49UdvWDMJ0WaoW9EjKlhAq6FH+a4P98Ia/epi1OI8xx294AOriuHlxethzEvQQTZCfEGFr4ntywXWx8D1ZVXTPfd7sxNiryYvJ1bCgmuou2ouyY1voUH6rim4w+FWdCF+5YPEazAP788ubY3qVHzOxi2zFcOsBqhiK8wsyc9Pr4GFLrZ2YfNCsMxDDGF2/rgnIZDoTQaye4AUUiNG0BoMyL6mNrmtf3PZHOBvB3SGLUTSghFlP0";
     String ltpa3DESKey = "yqaM5KH6fQhPRjuwFTlVWoJrHdYXOHNHp7ji+BJPSDM=";
     String ltpaPassword = "password";
     try {
         LtpaDecoder t = new LtpaDecoder(tokenCipher, ltpa3DESKey, ltpaPassword);
         System.out.println("UserInfo: " + t.getUserInfo());
         System.out.println("Username: " + t.getUsername());
         System.out.println("Expiry: " + t.getExpiryDate());
         System.out.println("Signature: " + t.getSignature());
         System.out.println("Full token: " + t.getFullToken());
      catch (Exception e) {
         e.printStackTrace();
     }
 }

The shared 3DES key is itself encrypted using the SHA hash value of the LTPA password (padded with 0x0 upto 24 bytes).
