SHA digest

Greetings

I am doing a Sha1 Digest on a file and compare it to what I'm doing a "Digest" SHAi in php.

However, my SHA results are different between php and Blackberry competely

Blackberry, I do

SHA1Digest digest = new SHA1Digest();

ubyte [] bytes = FileDirectories.readFileBytes (_filename);
Digest.Update (bytes);
Byte [] digestValue = digest.getDigest ();
            
Ret = ret + "\r\n";
            
for (int i = 0; i)< digestvalue.length;="">
{
b bytes = digestValue [i];
Ret = ret + Integer.toString (b & 0xff);
}

From php, I do

echo sha1_file ('Simulator_064.sdf');

Am I using the Digest of SHAI wrong or he incorretly >

After about three hours of testing, it seems that the problem is running the code on the Simulator. When I run the code on a real blackberry, it works very well - when I run on the Simulator, the SHA1 result is false if the size if the file is greater than about 400 bytes

BTW, I found an error in my code which could not add an extra 0 in front values with a single tank, set like that

b bytes = digestValue [i];
Var h = Integer.toHexString (b & 0xff) .toLowerCase ();
            
If (h.length)<>
{
h = « 0 » + h ;
}

That, however, had nothing to do with the problem

  • SNMPv3 user encrypted

    We have an SNMPv3 implementation that works for us for the last two years:

    Server SNMP user Mr MR v3 auth md5 priv aes 128
    Group Server SNMP v3 MR auth read snmpview write snmpview notify * tv. FFFFFFFF. FFFFFFFF. FFFFFFFF. FFFFFFFF0F
    Server SNMP view iso snmpview included
    SNMP-server host #. #. #. # version 3 auth ncm
    Server SNMP trap-source Loopback0

    Now, with our new MR tool, we want to implement SNMPv3 credentials on the new features and be able to change them in the future.  The question is we do not want to store the user server snmp cleartext passwords in the tool of MR.  I tried to use the following command:

    Server SNMP user Mr MR v3 encrypted md5 auth priv aes 128

    However, I always get a % error in the message of password authentication.  I tried the password in clear text (obviously false), as an MD5 hash and even as a Cisco of type 5 of hash, but I still have the same error.

    Is there something that is required before the MD5 hash or I'm supposed to be using a different method for the encrypted password?

    Hello

    did you follow the directives of formatting for encrypted passwords:

    If you have localized MD5 or SHA digest, you can specify this string instead of the password in plain text. The imprint must be formatted as aa:bb:cc:dd where aa, bb and cc are hexadecimal values. In addition, the digest should be exactly 16 bytes long.

    In the following example, the MD5 digest string is used instead of the password in plain text:

     Router(config)# snmp-server user abcd public v3 encrypted auth md5 00:11:22:33:44:55:66:77:88:99:AA:BB:CC:DD:EE:FF

  • SHA1

    Hello

    I try to get the type (php default) sha1 of a string. Here's what I have so far:

    SHA1Digest sha1Digest = new SHA1Digest();
    Sha string = "test string"; This string has been changed for security reasons

    sha1Digest.Update (SHA. GetBytes(), 0, sha.length ());
    Digest of Byte [] = sha1Digest.getDigest ();
    SHA = "";
    for (int a = 0;< digest.length;="">
    {
    SHA += digest [a];
    }
    System.out.println ("sha:" + sha);

    but it brings something like 69785171-7241-731860-91-81-11884-401-11041-56-40-88 for example, an incorrect value

    can you guys help out me? Anyone know what I'm doing wrong? Or maybe someone knows a better way to do this?

    Note: I already have stuff of security using the IDE Edit > preferences > Code Signing > RIM Crypto API (marked true)

    and all the keys have been acquired and installation

    Thanks for your help guys

    I agree with mreed that you use Integer.toHexString (0xFF & digest [a]). Also I suggest you use getBytes otherwise because your use is based on several aspects of default encoding. For example in some encodings .length str.getBytes () is not the same as str.length (). And there may be no appropriate code some non standard symbols. I suggest to use UTF - 8 (or uses the same encoding of your PHP code).

    private void doTest() throws UnsupportedEncodingException
    {
        SHA1Digest sha1Digest = new SHA1Digest();
        String sha = "teststring";
    
        byte[] inpData = sha.getBytes("UTF-8");
        sha1Digest.update(inpData, 0, inpData.length);
        byte[] digest = sha1Digest.getDigest();
        StringBuffer shaRes = new StringBuffer(40); //40 hex char is size of 160-bit SHA-1 result
        for (int a = 0; a < digest.length; a++)
        {
            String tmp = Integer.toHexString(0xff & digest[a]);
            if(tmp.length() == 1) //If hex value is "0X" then tmp is just one digit "X"      {
                shaRes.append('0');
            }
            shaRes.append(tmp);
        }
        System.out.println("shaRes: " + shaRes.toString());
    }
    

    This code gives me the same result as the implementation for the http://jssha.sourceforge.net/

    You can encapsulate byte [] inpData = sha.getBytes("UTF-8"); in try/catch and ignore UnsupportedEncodingException because as far as I KNOW UTF - 8 is supported by all BB devices.

    PS code is updated according to the mreedof fix for '0' in the result.

    We followed the Note 125767.1 six months back when we went to forms patches 19 group. I think force again he nessscary to reveiew because we're not modernize forms

    I thought that you are migrating forms as part of the JRE update, so since this isn't the case, you can skip this part.

    java.lang.SecurityException: invalid file signature oracle/forms/net/HTTPConnection.class.PRE_BUG12667746 SHA digest

    Don't know why a saved the oracle/forms/net/HTTPConnection.class.PRE_BUG12667746 file is selected by the form?

    Most likely, it is the reason for the error you are getting.

    Have you tried re - implement the steps in the README file in 12667746 patch ?

    What happens if you rename the existing file and copy the main class as PRE_BUG12667746, make the same mistake?

  • BB10: 880 META-INF/RDK. SF: Incompatibility of SHA-512-Digest-manifesto

    Hi guys,.

    I can't install my application signed in the unit. When I try to do, I get this error:

    880 META-INF/RDK. SF: Incompatibility of SHA-512-Digest-manifesto

    Somethings:

    • I can install my application on the device with the debugging token and it works fine.
    • My signed application used to work properly. I think that the problem started after I updated my SDK, 10.0, 10.1.

    Any ideas on how to solve this problem?

    I've been stuck here for a while now.

    Thank you all!

    I solved it!

    I just changed the SDK supported 10.1.X.X to 10.0.X.X

    It's not elegant, but it works.

  • Problem with sha-256 digest: missing zeros!

    Hi, I'm doing a "Digest" sha-256, leave a string, it's that in the digest resulting some zeros are missing!

    Digest itself is not wrong: other characters are very well... for example, let's say I had a string like this:
    '64C6DDE3E579B6D986968D3445D23B15CAAF128402AC560005CE2075913FDCE8363739303358303038323339330025532682B1 '.
    Correct sha256 digest would be:
    '0986d134680fa055c32f86738ad67108c8028a2ea6fc31d5d64b5c8e43901f42 '.
    but I get
    '986d13468fa055c32f86738ad6718c828a2ea6fc31d5d64b5c8e43901f42 '.

    Here is my code:
    String beforeHash = aString;  //each couple of chars is a hex number so ...
    byte b[] = (new BigInteger(beforeHash,16)).toByteArray();
    String result = getHash(b);
    System.out.println(result);
    
    public String getHash(byte[] passwd) throws NoSuchAlgorithmException{
              MessageDigest msg = MessageDigest.getInstance("SHA-256");
              msg.reset();
              byte output[] = null;
              msg.update(passwd);
              output = msg.digest();
              StringBuffer hexString = new StringBuffer();
              for(int i=0;i<input.length;i++)
                   hexString.append(Integer.toHexString(0xFF & output));
              return hexString.toString();
         }
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            

    Not a problem in Cryptography. Integer.hexString () does not preserve the leading zeros. Change to use String.format("%02X",v) or use one of the free hexagonal encoders.

    Any ideas what could cause this error?

    First I thought maybe it's because the same mistake: what to do if your Package ID was rejected by BlackBerry App World

    But the creation of a new element of product does not help with this problem.

    It is a native application of qml Qt. It does not store the files, need to no write access and uses only simple, free of components created 1.0 QtQuick with no additives. So, it should be the best portable application out of my small collection.

    Unfortunately I have no real device here since I, like many of you, to present one of my tablet at BB App World Applications, first to get a.

    Google was not my friend on this topic, so I hope someone has this kind of error message and could tell me what could bring it. Any kind of advice are welcome.

    Best regards

    FYI, a new simpler command allows to sign the 1 step:

    BlackBerry-sign - storepass .bar

    P12 both RDK of passwords must be the same, but this measure will apply to both the two signatures. It should have the same results as the command that you run.

    Eager to hear feedback on this...

    Best regards.
