Java Encryption C# Decryption -

-

I have found a module that encrypts RSA data and passes to C #. C # need to be decrypted based on public key (64 bit encoded) and passed token.

I have tokens, 64-bit encoded public, something can help me get samples to get started. I know from all the java end, it is using. I got the results from Java end and need to write parser in C # to decrypt it. I get both a public key and a token in the form of a string value. 

  cipher cipher = cipher Past insertion (algorithm); // algorithm = "RSA" cipher. It (cipher dircp_mode, key);

Thanks

To get started, you need to decrypt the message To do this from the Private key "Public Key (64 bit encoded)", I think that in fact you have base-64 & ndash; Encoded certificate, which has a header line which is "----- BEGIN certificate -----" and a footer that says "----- end certificates -----".

If this is correct, you will need to find a private key. It is sometimes stored in a PKCS # 12 format file, with a ".P12" or ".pfx" extension, the private key You will need a password to access if it is stored in such a file.

Alternatively, OpenSL and other utilities use private key files that are base-64 & ndash; Can be encoded or binary. They contain several types of extensions, and may not be password-protected or otherwise. If you have a file that contains "----- RSA Private Key -----" or "----- Private key -----" is the title line, which is actually a private key.

Finally, Windows can store the private key in its internal key store.

When you clarify the location of the private key, please update your question.

If the private key is used on the Java side, it may be an attempt to demonstrate a digital signature when I have tested many Java providers, producing the right results. Time (AB) is used in this way, if you are signing a sign then the signature class should be used. The C # code should also be used as a "signature" signature object.

The encryption is done with the private key, because the public key is public; any message can decrypt; That is, the message is not confidential. Public keys are used by recipients to verify signed messages.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
