Problem in using HMAC SHA1

Hi,
I have written an applet to sign with ALG_HMAC_SHA1. I'm testing it with the CREF given with the Javacard Kit 2.2.2 but it does not work.
The getInstance just throw the exception.
the Code is :
public OTP_RFC4226() {   
        try{
        hmacSha1 = Signature.getInstance(Signature.ALG_HMAC_SHA1, false);---
If any one have an idea i would be please.
Thx.
Cauch

I have one good news and one bad news for your guys;-
The Bad news: The Javacard API has ALG_HMAC_SHA1;ALG_HMAC_SHA_256;ALG_HMAC_SHA_384;ALG_HMAC_SHA_512 support on paper, but more less only on paper. Not much cards support them. ( I found one Renesas card which support it, feel free to correct me)
The Good news: almost all the Javacard support ALG_SHA, please read ALG_HMAC_SHA1 algorithm to see how to impletment your own ALG_HMAC_SHA1 base on ALG_SHA. ( It is easy pieces of cake)

  • Hmac sha1 signature generation error.

    I'm using Flex Builder 4 for accessing cloudstack api and for getting responses. When i execute my flex program, the url is generated with commands, api and the signature. But the Xml is showing an error as below:

    Is it the problem of encoding signature.? I'm using Hmac Sha1. When i did the process in python i got the output as list of zones. 
    Can anyone help me to correct the error?
    Thanks in advance!

    Did you ever determine an answer or solution to this?...some feed back whether you were successful or not would be interesting...

  • HMAC SHA1 Signature for google

    Hi,
    I need to build a google signature using HMAC SHA1 and find a way to do it on our WAS 6.20 system
    You can see the google explaination underhttp://code.google.com/apis/maps/documentation/premier/guide.html#URLSigning.
    I Beleive I can use FM SSFC_BASE64_ENCODE and SSFC_BASE64_DECODE to do the base64 parts.
    However, I don't know how to do the HMAC SHA1 part.
    We don't have FM's like CALCULATE_HMAC_FOR_RAW in our system so I think I'll have to create a new FM but I have no idea how to build this.
    Any ideas?

  • Ksetup: Enforce use of AES256-CTS-HMAC-SHA1-96 fails

    Hi,
    Windows 7 Home Premium x64 authenticating to a Kerberos 5 install on Ubuntu 14.04.2.  Please note the problems are not with the latter part, several Linux clients use the Kerberos KDC without issue, and an install of "Kerberos For Windows"
    with "Network Identity Manager" on the Windows 7 client works fine, but it does not integrate with the rest of the system, so...
    I have used Ksetup to set the realm, add a KDC, mapped the local user to the principal, and set the machine password (principal exists in the KDC); no problems.  However, the KDC is configured to only accept AES256-CTS-HMAC-SHA1-96.
    When I try the following it does not work:
    C:\>ksetup /setenctypeattr REALM AES256-CTS-HMAC-SHA1-96
    Setting enctypes for domain REALM to:AES256-CTS-HMAC-SHA1-96
    Setting enctypes on REALM failed with 0xc0000034

    Query of attributes on REALM failed with 0xc0000034
    Failed /AddEncTypeAttr : 0xc0000034
    When I perform a kinit, this is apparent (note that this is getting a response from the KDC, as using an invalid username results in a different error explicitly stating that it is invalid):
    C:\>kinit username
    Password for username@REALM:

    I have already set in the Group Policy settings the value of "Network security: Configure encryption types allowed for Kerberos" to "AES256_HMAC_SHA1" only.
    How can I force Windows to use the correct encryption type?
    For completeness, output of ksetup below:
    C:\>ksetup
    default realm = REALM (external)

  • HMAC (SHA1) key longer than 81 characters not possible?

    Not sure whether I'm in the correct forum...
    To sign a message for a specific application with HMAC-SHA1 hash I need a 83 character key.
    My problem: the function module 'SET_HMAC_KEY' throws the exception "param_length_error". After I've testet with several key length, I found out, that the maximum valid length is 81. Is there any reason for this?
    With 3rd party libraries (ie. Python and Javascript) longer keys are working.

    I truncated the key further because in a coding tag it toasts the formatting when too long.

    Hi,
    yes, we can :-). Let say that SAP implementation supports a key with size more than 81 bytes. Then according to specification if the key is longer than block size of hash function (64 bytes for SHA-1) then it would use hash function to reduce original key to new key with size equals to output size of hash function (20 bytes for SHA-1). Therefore doing this step manually before calling SET_HMAC_KEY is equal to calling SET_HMAC_KEY which supports keys longer than 81 bytes.
    The easiest way how to check this is to compare some HMAC-SHA1 implementation with the result produced by my proposed logic.
    DATA: text TYPE string,
            key_str TYPE string,
            hash TYPE hash160x,
            key TYPE xstring,
            hmac TYPE hash512_base_64.
      text = 'Hello'.
      key_str = '012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789'.
      CALL FUNCTION 'CALCULATE_HASH_FOR_CHAR'
        EXPORTING
          data  = key_str
        IMPORTING
          hashx = hash.
      key = hash.
      CALL FUNCTION 'SET_HMAC_KEY'
        EXPORTING
          generate_random_key = space
          alg                 = 'SHA1'
          keyxstr             = key
          client_independent  = space.
      CALL FUNCTION 'CALCULATE_HMAC_FOR_CHAR'
        EXPORTING
          alg        = 'SHA1'
          data       = text
        IMPORTING
          hmacbase64 = hmac.
      WRITE: / hmac.
    Javascript version
    var hmac = Crypto.HMAC(Crypto.SHA1, "Message", "Secret Passphrase");
    var hmacBytes = Crypto.HMAC(Crypto.SHA1, "Message", "Secret Passphrase", { asBytes: true });
    var hmacString = Crypto.HMAC(Crypto.SHA1, "Message", "Secret Passphrase", { asString: true });
    Both implementations return "qsXNz/wecK4PMob6VG9RyRX6DQI=".
    Cheers
    Sorry for formatting but it looks like something is broken.

  • Kerberos local DC problem when using screen sharing

    Hi,
    this is a brand new Mac Mini server with preinstalled ML and Server.app 2.2.1.
    I started the following services: DNS (automatic), OpenDirectory, Sharing, Web and Mail. One additional user and that was it.
    After this configuration session, Kerberos seems to be in a non-operable state. See the information below. I can log in locally, can access a share (similar LKDC related error message as below), mail and screen share. But screen share takes ages to start and gives some nasty error messages.
    I have almost no knowledge of Kerberos and could use any help to fix-up the Kerberos configuration, preferably without reinstalling.
    If there is anything else you need to see about the server configuration, please ask.
    Turnin OD off and on again did not change anything. Keeping it off removes the error (obviously) but I think this will not be good for server operations.
    Regards, Andreas
    Problem statement: accessing the server from a ML client gives the following KDC error sequence before the authentication succeeds. This can take 20-30 seconds.

    The Kerberos part of the server open directory settings:
    dirserv:kerberizedRealmList:availableRealms:_array_index:0:dirNodePath = "/LDAPv3/127.0.0.1"
    dirserv:kerberizedRealmList:availableRealms:_array_index:0:realmName = "MARVIN.DOMAIN.DE"
    dirserv:kerberizedRealmList:defaultRealm = "MARVIN.DOMAIN.DE"
    So far all fits AFAIK and the domain is also correct.

    After a night of experimentation, I found a workaround but do not know if this simply avoids Kerberos authentication or what is going on.
    It can be a domain problem except for the checkLocalKDC error that needs to be fixed anyway.
    Above I used the server occurrence in a Finder window, which I presume takes as a name marvin.local.
    Then I used a Go to Server vnc://marvin which worked without a Kerberos error. Also marvin.fritz.box (router) works fine.
    marvin.local looks up the machine via Bonjour, right? Can this be the reason for the difference in authentication?
    My domain setup is likely illegal at the moment:
    local DSL router does the DNS/DHCP for local devices
    server marvin has its own dns for marvin.domain.de (reason below) alone and otherwise uses the router dns
    domain.de is a registered domain (mine) with fixed ip and server behind
    Reason: the domain.de server will be replaced by a DynDNS provider forwarding any request to my dsl router, which acts a firewall and port forwarder.
    So my reasoning was that the new server marvin should be in domain.de as from the point of view of the internet, it is the machine at domain.de. Except that during setup and tests, it is not.
    The client accessing marvin however has no idea about marvin.domain.de! It uses the router as the dns.
    If anyone has done a similar setup (server behind router-ISP-DynDNS), I would appreciate examples how you setup the dns such that the server acts properly from the outside world of view.
    And yes, there is a MX at domain.de and SMTP requests will be forwared to marvin also.

    The warranty for the iPhone is not and has never been International.
    Warranty and support are ONLY valid in the country of origin.  The only exception is the EU where the entire EU is treated as one country.
    If the device will be used in India, buy it in India.

  • Problem on using Crystal Report Viewer on windows application ("specified type is not valid ")

    Hi
    I am having problem on using Crystal Report Viewer on one of my windows application.
    I am not sure how to put the Crystal Report Viewer 11 Control onto the tool box.
    I could found a Crystal Report Viewer control on my computer, but it is version 8.5.
    I have also found another one which is Called Crytal ActiveX Report Viewer, i don't think it is the one I can use. As when I try to load a dummy report on to the Crytal ActiveX Report Viewer, It return an error. "specified type is not valid"
    Please see the Code sample below.
    private sub loadReport()
         Dim r as New ReportDocument
         'v is the name of the Crystal ActiveX Report Viewer Control
         r.Load("C:\Report1.rtp")
         v.ReportSource(r) <---It throw error on this line.
    End Sub
    Could you give me some advice about what have I done wrong, How to check if I have set up the Crystal Report Component correctly in my Visual Studio 2005 Standard edition.
    Thanks in advances.
    Many thanks
    Chi

    VS 2005 Standard and Express editions do not come with Crystal Reports; only the Professional and higher editions will have CR bundled. However, I believe you can purchase CR XI R2 Developer and it will give you the components you need to create a VS .NET 2005 application using the Standard edition.

  • I have two Iphones with different email addresses sharing one Apple ID. Will that cause problems with using messaging and FaceTime?

    I have two Iphones 5 with different email addresses sharing one Apple ID account.Both are using IOS 8.
    I would like to set up a new Apple Id for one of the phones and remove it from the old account.
    If I do that, can I move all of the purchased apps and songs to the new Apple account?
    Also, will sharing one Apple ID account with two devices cause problems with using messaging and FaceTime?

    Sharing an iCloud account between two devices can be done without causing issues with iMessage and FaceTime, just go into Settings for each of these functions and designate separate points of contact (i.e. phone number only, or phone number and unique email address).  While that works, you'll then face the problem where a phone call to one iPhone will ring both if on the same Wi-Fi network -- but again, that can be avoided by changing each phone's settings.
    Rather than do all that, don't fight it -- use separate IDs for iCloud.  You can still use a common ID for iTunes purchases (the ID for purchases and iCloud do not have to be the same) or you can use Family Sharing to share purchases from a primary Apple account.

    I have no communication with my that friend :/ So it means i need to delete those apps? There's no other solution to update those apps?
    No.  purchases are forever tied to the apple ID used to buy them.  Delete them and buy your own copies.
