In windows, encryption and decryption are normal, while in linux, the following exception occurs: javax. crypto. badPaddingException: Given final block not properly padded at com. sun. crypto. provider. sunJCE_f. B (DashoA13 *..) at com. sun. crypto. provider. sunJCE_f. B (DashoA13 *..) at com. sun. crypto. provider.

AE SDecrypt (AESUtils. java: 254) at chb. test. crypto. AESUtils. main (AESUtils. java: 40) www.2cto.com solution: After checking, locate the method for generating the KEY, as shown below: [java] public static SecretKey getKey (String strKey) {try {KeyGenerator _ generator = KeyGenerator. getInstance ("AES"); _ generator. init (128, new SecureRandom (strKey. getBytes (); return _ generator. generateKey ();} catch (Exception e) {throw new RuntimeException ("An Exception occurred during key initialization") ;}} Changed to the following method. solution: [java] public static SecretKey getKey (String strKey) {try {KeyGenerator _ generator = KeyGenerator. getInstance ("AES"); SecureRandom secureRandom = SecureRandom. getInstance ("SHA1PRNG"); secureRandom. setSeed (strKey. getBytes (); _ generator. init (128, secureRandom); return _ generator. generateKey ();} catch (Exception e) {www.2cto.com throw new RuntimeException ("initialization key Exception ");} Cause analysis: Is SecureRandom fully implemented? Operating system itself? Acetylene ?? B, unless? Users in? After using the getInstance method? The setSeed method is used. The key generated every time on windows is the same, but it is different on solaris or some linux systems.
