    <p>RFC2898 is the official name for PBKDF2 (Password Based Key Derivation Function). </p> <p>This question seems to use the <code>SecretKeyFactory</code> class for PBKDF2. </p> <p><a href="https://stackoverflow.com/questions/2375541/password-verification-with-pbkdf2-in-java">Password Verification with PBKDF2 in Java</a></p> <p>If you cannot find any implementation that you are satisfied with, I suggest you take a look at <a href="https://stackoverflow.com/questions/3210795/pbkdf2-in-bouncy-castle-c-sharp">my question</a> where I used a few classes from BouncyCastle (for C#, but should work for Java) and created the algorithm. I had to create this for C# because there was no <code>Rfc2898DeriveBytes</code> for the .NET Compact Framework.</p> <p><a href="https://stackoverflow.com/questions/8674018/pbkdf2-with-bouncycastle-in-java">This question</a> should definitely help you too!</p> <p>You can also find an implementation <a href="http://www.jmedved.com/2010/05/java-rfc2898derivebytes/" rel="nofollow noreferrer">here</a> that was done by someone who stumbled across your same problem.</p> <p>Also to answer the second part of your question,</p> <p>Rijndael doesn't differ much from AES. To quote this <a href="http://blogs.msdn.com/b/shawnfa/archive/2006/10/09/the-differences-between-rijndael-and-aes.aspx" rel="nofollow noreferrer">webpage</a></p> <blockquote> <p>Namely, Rijndael allows for both key and block sizes to be chosen independently from the set of { 128, 160, 192, 224, 256 } bits. (And the key size does not in fact have to match the block size). However, FIPS-197 specifies that the block size must always be 128 bits in AES, and that the key size may be either 128, 192, or 256 bits.</p> </blockquote> <p>Rijndael algorithm was chosen by the NIST to be the Advanced Encryption algorithm.</p> <p>So you can use the <a href="https://stackoverflow.com/questions/992019/java-256-bit-aes-password-based-encryption">AES algorithm in Java</a>.</p>

    1. COThanks for your answer, but even I know the encrypt algorithm is rijndael/AES and how to use Java to encrypt data with AES, I've still no idea about how to translate the original C# codes, especially the rijndael declaring parts. Currently, I've finished translate Rfc2898DeriveBytes in Java. Could you please give me more information about how to translate the remain parts? Thanks

    2. COYou are not going to be able to convert the code line by line to Java mainly because there's no `CryptoStream` class in Java. Take a look at this [question](http://stackoverflow.com/questions/4599113/encrypting-and-decrypting-string-using-a-java-equilavent-of-the-c-sharp-cryptost) as well.

    3. COThanks for your reply. I have rewritten the whole Rfc2898DeriveBytes class in Java, and use java's build AES encryption method, however, it still not works for me. For example, IV's length is limited to 16 in Java. Could you please provide some working code samples for the 150 reputation.:)

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
