Decryption and encryption RSA

Dear Sir
I would like to encrypt the hash data in the card sent by the host application java applet. I'm Bravo encryption, here my card supports the Protocol T = 0 so what I want is to send the data in an APDU and also to receive data encrypted as a result of the APDU even, is it possible? or I should write two different commands for encryption and encrypted data. ??

His work, but why it's causing problems? Please explain the reason.

You can only assign the outgoing APDU once. setOutgoing and setOutgoingAndSend both for this. It's in the doc of the APIs for APDU.

And also what is the maximum length in return by the method of doFinal()?

It depends on the encryption algorithm you are using. With RSA encryption, it's the same as the size of the key module.

  • Disable the protocols and encryption algorithms in VMware View connection server and security

    Hello

    In my recent deployment, I had a customer request to disable some protocols and encryption at the Server VMware View connection and security. I read some articles and found that this has been achieved by editing the locked.properties file. But when we have edited and replaced the file, users could not connect to the virtual desktop, so came back to us backwards and desktop computers worked fine.

    I found a few articles that we don't need to edit the locked.properties file in VMware view Horizon 6. If someone has done this please guide me through. Here are the details of the protocols and encryption algorithms that should be disabled

    Diffie-Hellman key

    Enable SSL v2/V3 and TLS 1.1 and 1.2

    Disable the RC4 encryption algorithm

    Select the secret of transfer (if possible)


    VMware view 6 is the connection to the server and security server.


    Thank you.

    Hello

    I implemented the following steps (from the manual):

    1. update the JCE policy files to take in charge the high-strength Cipher Suites

    You can add some cipher suites of high resistance for greater assurance, but first you must update the local_policy.jar and US_export_policy.jar files to each server instance and the security strategy for JRE 7 see connection to the server. You update these policy files by downloading the files to extend JCE (Java Cryptography) unlimited strength political jurisdiction from the Oracle Java SE download site 7.

    If you include some high-strength cipher suites in the list and you do not replace the policy files, you cannot restart the VMware view Horizon connection to the Server service.

    Policy files are located in the directory C:\Program View\Server\jre\lib\security from VMware.

    For more information on the download of the JCE unlimited strength jurisdiction policy 7 files, see the Oracle Java SE download site: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

    After you update the policy files, you need to create backups of the files. If you upgrade the instance of the view connection server or security server, any changes you have made to these files can be replaced, and you may need to restore the backup files.

    2. the changes that policies of global acceptance with ADSI Edit

    • Start the ADSI utility on your computer see connection to the server.
    • In the console tree, select Connect to
    • In the selection or type a unique name text box or a naming context, type the unique name
      DC, DC = vdi is vmware, DC = int.
    • In the type or select a text field or the server box, select or type localhost: 389 or the name of a fully qualified domain (FQDN) of the server computer to connect to port 389 followed view.

    For example: localhost: 389 or mycomputer.mydomain.com:389

    • Expand the tree of the ADSI Editor, OU = properties, select OU = Global, then select OU = common in the right pane.
    • On the object CN = common, Global = UO, UO = properties, select each attribute that you want to change and enter the new list of security protocols or cipher suites.
      I used the following settings:

    EAP-ServerSSLCipherSuites: \LIST:TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA256

    It is not the highest possible, but they work with all the features of our customers.

  • How to decrypt previously encrypted files when the certificate is lost

    I've already posted a question and received a response. I would now like to make additional comments on what I said in my previous question. Maybe I used the wrong term and said "my computer crashed." In fact the computer has successfully started as always, so I restarted for some reason, but this time, he was able to start, displaying "NTLDR is missing". Press CTR + ALT + DEL is not started the computer. I have do not reformat the hard disk, but simply to insert the CD of the OS to set up the operating system on the existing system. As part of the implementation, I did inadvertently in my name, when asked "who uses this computer" so I became a Director. In the previous original set-up the built-in administrator is the only Director; my name appeared as a user. Now when I check the local users in the Computer Management Console the built-in Administrator, the only Admin previously, and myself ERHAN KARABEKIR are displayed as properties for each user and users lists each of the two as a member of administrators. I want to come is I think I hope the previous built-in administrator could somehow be recovered. Am I too optimistic? Today, I disconnected to switch users, hoping that the built-in administrator would appear as a user so that I could open a session to be able to decrypt the files and folders encrypted. Unfortunately, he did not show I've been to ERHAN KARABEKIR, my present administrator account. Previously, the administrator displayed in users in the Panel was 'Administrator' and the guest account, without any name. I bought the computer with an operating system already installed. Now, my name is displayed as "administrator of the computer. Sorry for the long explanation.

    If you are lucky enough to make the administrator account is the original account whose profile includes the certificate required to access the encrypted files, then simply connect to your computer as 'administrator '.  You will not be able to see the administrator account on the logon screen if you have created another account.  To connect as an administrator, when you get to the login screen, hit Ctrl-Alt-Del twice.  You can then type "Admin" in user space and the password in the password space and log in as an administrator.

    Good luck

  • Cannot decrypt previously encrypted files

    I had a record that I apparently encypted on my old pc, and I moved the drive containing this folder on my new pc as a 2nd hard drive. Now, all the file names are green and I can't access the file or if I can decrypt the files.

    When I try to move the folder, it says I need permission from Fatso666/Eamon, who is the name of my pc and my user name, IE the user I use now...

    I still have my old pc and so I exported the certificate of security and then he imported on my new pc, but when I try to uncheck the option encrypt it said access denied.

    Had a similar problem after my Windows 7 OS crashed and restored on the same machine id, even user and did not have access to previously encrypted files. The way I fixed it, I searched the files *.pfx, found a backup system efs, right clicked and selected 'install PFX', then got another screen where I entered the password I used when I encrypted file, he agreed and got the message my certificate has been restored. Went into the ownership of the encrypted folder, then select this option to remove encryption and hollow it went Ok. I hope this helps... VIC

  • Run the command of MaxL througth ODI and encrypt the password

    Hello

    I'm looking for a solution not using password plain text for my order Maxl in ODI.

    Someone knows how can I do?

    So far, I found nothing.

    Thank you

    Alain

    Hello

    Here is an example to encrypt the connection information in a scipt maxl.

    Something like this first run the command prompt
    essmsh - gk > c:\temp\encryptKeys.txt

    This will create a text file with the key public and private for example
    for example
    Public key for encryption: 5407,1453704157
    The private key for decryption: 406488703,1453704157

    Now that you have a maxl file called login.mxl as

    login password admin on localhost.
    disconnection;

    You can encrypt by calling
    essmsh EI c:\temp\login.mxl PUBLIC KEY

    So for this example, it would be
    essmsh EI c:\temp\login.mxl 5407,1453704157

    This will create a file called login.mxls with encrypted for example connection details

    Login $key 6343689380045143584028576355606972733930 1468602100275634090163724540502857635560 localhost $key;
    disconnection;

    Now, to run the file, you must use the command
    essmsh d c:\temp\login.mxls PRIVATE KEY

    Thus, in this example
    essmsh d c:\temp\login.mxls 406488703,1453704157

  • reset question and encryption Time capsule

    I have reset my Time Capsule with a hard reset (power off and the reset button on TC).  I've reset with the same password but do not know if my TC drive is always encrypted with the same password as before the hard reset.

    I lost control of my time Capsule when I changed to "DHCP and NAT" bridge mode  My TC works in an existing network with an Ethernet connection to the modem router modem/router for the broadband (Comcast) data and a separate wireless network.  I was watching my TC and noticed a few unidentified wireless clients. Without thinking carefully, I asked myself why I was in Bridge mode and past my TC bridge DHCP/NAT form.  Oops.

    I believe me who put in a double NAT situation and I have lost visibility and control my TC - I couldn't see or effect framework with Airport utility, running on a client computer wireless.  I tried several things but finally reset the TC and the same password of TC and set mode Bridge (the default value).  The backup disks safe when I look into TimeCapsule, I still show want to ensure that they have the same password as before I have not reset or tenant an encryption password.

    Reset a Time Capsule will not change the format of the disc. This requires the use of disk utility with the time Capsule disk tab Airport utility. The drive isn't yet sure unless you also reformatted it. It does not read like you did.

    If the Capsule worked properly in bridge mode, then be sure to return to this mode if you connect to another, not Apple, router or modem/router. If the Capsule is your only connection to a cable or DSL modem device, you can use normal DHCP.

  • Is that you can decrypt an encrypted file without having the certificate?

    I upgraded from XP to W7 and XP has apparently decided to encrypt all of my photos and videos of girls newborn without knowing me.  I have a C: drive and a partition of drive Z:.  I moved all the pictures and videos I wanted to drive Z: (not knowing they were numbered randomly) and installed W7 on my C: drive.  I'd erase everything on my C: drive to install W7 and save memory on my computer for me (this included the windows.old he created).  At the moment where I realized my files have been encrypted and it wasn't a matter of admin, System Restore does not go enough distance to when windows.old was still on it.  So now, I have all these encrypted photos and videos and get the woman's tongue lashings.  Anyone know of any possible solution or is all lost?

    There is no way that the files 'XP apparently decided to encrypt' Native XP encryption can be done automatically. Encryption peut happen without your will, only if the computer is infected with one of the variants of ransomware Trojans. But you'd get messages of "blackmail". Otherwise, you'd encrypt the files yourself, not something you could do without intending to. What makes you think that files are encrypted? If you get an "Access denied" error message all you have to do is to take possession of the files . If you really encrypted files using EFS native process of XP (again, not something you could do without knowing what you were doing) and does not back up the certificates, the data is lost. You can communicate with people of Elcomsoft to see if their program might help; If this isn't the case, then the data is permanently inaccessible forever.

    Hello and welcome to the community!

    From what you describe, there is a COMPUTER on your BB policy which is demanding both encryption and a password for the device-lock. If you are currently on the BES, then STOP NOW and see your BES admins they control it.

    If you are not on BES, somehow your BB has a COMPUTING policy... the cause maybe it was once associated with BES, but not properly deleted when the property was transferred to you. If all goes well, there will be other problems that often comes with "2nd hand" situations. In any case, you can check this:

    • KB30076 How to check for an it on a BlackBerry smartphone policy

    Even if does not appear as described, from what you have described, there is probably a COMPUTER policy that is causing this (some may be "hidden"). To remove it, first make sure you have a good backup of your BB... See the link in my sig auto on this post for instructions. Then do this:

    • KB31291 How to reset a BlackBerry smartphone to factory using BlackBerry Desktop Software Settings

    Thereafter, your BB will be as new... you need to re - install your applications and restore your data (according to the backup you took my instructions above). BUT - when you restore data, DO NOT make a full restore... rather, only restore these databases you need (e.g., Contacts, calendar, Messages, etc.) and more precisely to avoid those who have nothing to do with the COMPUTER policy, company or similar things... If you restore, you will be right where you started.

    Good luck and let us know!

  • Using a Cisco VPN on iPad and incorporating RSA tokens

    Hello community of Cisco,

    I have what seems like a simple question.  I have almost no experience network so hopefully someone here can answer that.  I have this project iPad for my internship in which they want to create a remote access to their network using a VPN and a soft/hard security token.  It seems that they already use hard tokens RSA for their current home VPN connections.  They use portable computers to their home but want to start using iPads as well.  So my question is, an iPad can support a Cisco VPN using hard tokens RSA authentication? I just need a concrete answer to the management of work and literally just give them somewhere to start.  Thank you for taking the time to read my question and reply.

    Phil,

    AnyConnect on iphone/ipad/ipod should be able to handle hardtoken auth, but with softoken itegration could be problematic (the last time I heard that it was not supported at all).

  • Problem ACS 4.0 and Server RSA Token

    Hello

    We are having a problem trying to get 4.0 for Windows GBA authenticate users on a Server Token RSA wireless.

    Our Cisco 1200 AP series is configured for WPA2 and LEAP Authentication. He points to the ACS server for RADIUS authentication. Now, it works very well for users with a static password defined on the internal database of GBA. However, for obvious security reasons, we? d as the transmitted authentication to our server internal RSA.

    I installed RSA Agent on the same server as the ACS along (after adding the sdconf.rec file in the System32 folder). The RSA server was added to the ACS external database and a user configured to use the Token RSA server for password.

    When we try to authenticate, the ACS fails the attempt with reason? External DB passes invalid?. The same user can authenticate successfully during the use of the RSA test authentication tool that is installed on the ACS server under the RSA Agent software.

    After running some debugs a pix in front of the servers, I see traffic to and from the servers when you use the test tool (that works), but it looks like GBA doesn't? t even send traffic to the RSA server during authentication.

    Any help or advice appreciated.

    Thank you

    no no no no! Do not use EVER of RSA with WIFI + PAP.

    The token + pin can be sniffed and is good for 60 seconds... on the Wifi which is disastrous.
