the resources I have modified the code. Java source on the GitHub download address is: https://github.com/platinumjesus/crypto015, You need to download the Us_export_policy.jar and Local_policy.jar packages that correspond to your JDK version and replace the two packages in your installation directory, otherwise there will be a problem.

Please help me with this simple problem. i'm trying to create an sslserversocket that is enabled with the 2 AES 256-bit cipher suites that are supposed to be available in jdk1.4.2. as you can see in the following code, when the program attempts to enable the sslserversocket, SS, with cipher_suites, an exception occurs. the exception basically says that the tls_dhe_rsa_with_aes_256_cbc_sha cipher Su ITE wasn
An error occurs when the encrypted string is about 30 bits. if you do not know why, an error occurs when the generated key length is about 30 bits of 256 bits, the length of the generated key is 256-bit reply content: plaintext length (Bytes)

These days busy doing graduation design, busy knocking code, early found as the original "boring" of those technical words to knock again is not much significance, because it would be better to write down the time it takes to read it carefully or use the code to do a few practical examples, but it's a good idea. Mainly because too want to be a teacher! Now, do not do so do not write because of the temporary give up the plan to be a teacher, the two days of free time to review the database, turne
