• Repeatable encryption with RSA public key encryption

  Hello
  
  I have the following problem: I try to encrypt a byte array with an RSA public key encryption and want to get the same byte array encrypted for every call to doFinal().
  
  Object*.
  Two people (a and b) may share the same secret. Yet they don't trust each other until what they have confirmed that they share the same secret. To check if both share the same secret the following protocol apply (via a communication channel not secure assistance from person c they don't trust either). Also, there is no one which may help to establish trust (i.e. building confidence channels).
  
  (1) generates the public key / private RSA
  (2) a figure his secret with the RSA public key
  (3) one sends the secret encrypted with its public RSA key for b
  (4) b uses the RSA a public key to encrypt his secret
  (5) in the case of the encrypted secret of a matches the secret encrypted b, then make (6), if a and b do not share the same secret, as they are in conversatzion
  (6) b generates his own public key / private RSA
  (7) b figure (not encrypted) secret with its private key
  (8) b figure his secret (encrypted with its private key), as well as his public key with the public key of a
  (9) b sends his secret (encrypted with its private key) and its public key in a
  (10) one decrypts the secret and b public key with its private key
  (11) one decrypts the secret with the public key of b
  (12) checks if the secret received b acually meets that one knows = > trust established, finishing
  
  
  So, I want to achieve is that the following code prints "true":
  

  byte[] potentialSecret = new byte[]{1, 2, 3, 4, 5};
  KeyPairGenerator kpg = KeyPairGenerator.getInstance(RSA);
  kpg.initialize(512);
  KeyPair kp = kpg.generateKeyPair();
  PublicKey key = kp.getPublic();
  Cipher c = Cipher.getInstance(RSA);
  c.init(Cipher.ENCRYPT_MODE, key);
  System.out.println(Arrays.equals(c.doFinal(xy), c.doFinal(xy)));

  I tried to 'tinker' with initialization vectors, but still finished with the exceptions of various type.
  
  
  Thank you very much

  How can PS: btw, I markup code? It is my first assignment in the Oracle forums.

  If your security is based on a secret that can be 8bits then you only 8bits of security. An attacker could send a request with their own key pair with all the data. The other party would return the text key and the encryption algorithm and then after less than 256 RSA cryptographic operations you have the secret (if it's 1 byte). You can then send the request with the correct secret.

  See you soon,.

• Why all these hundreds of iMessage Sign In and key encryption keys?

  Since el Capitan, upgrade of hundreds of iMessage Sign-In and encryption keys are listed. If I decide to delete one of them, a dialog box gives me a terrible warning.

  Are these important, a security feature or just a pain?

  Hello

  Each cat to iMessages you is encrypted.

  The keys are saved so that you can view the cats later if you save them.

  The size of the key file is very small and even total not not worthy to be that barely thereon.

  There are a couple of threads on this topic with some saying that they do not want to keep them now.

  I'm not sure that someone tried to delete them and see if it looks an effects older cats.

  Is anyone able to tell me why my module is bad?

  Understand my question, the RSAParamsCreate wants to have the size of the key in BITS that I had trouble backtracking 1024, 2048, so my modChar necessary to the size in BYTES to create a modChar [128] and the params size 1024, and then in the set of keys, I have the size be 128.

• Issue of encryption of RADIUS

  Hello

  I would just check what type of encryption used by saying a Radius Server and a Cisco network device.  References online as the RADIUS only encrypts the password but I can't seem to find any info on what type of encryption.  I am inclined to believe that the password is encrypted using the brightness button before but what type of encryption (3des. aes?)?

  Thanks in advance.

  It uses the MD5 hash.

• Over 2 years factory restore, Windows 8 Gateway fails to validate Windows 8 from the bios encrypted

  Hi all. For two weeks now, I tried to help a veteran 84-year difficulty his virus infected Office Windows 8 Gateway (Walmart) age of 2 years old.

  The poor old man was a PC buyer first time when he bought this PC two years ago & didn't have understand the consequences of not renewing its 60-day trial version antivirus. Therefore after continuing to run his PC online almost two years later, it was badly infected. I went there to help a couple of weeks & he was clearly infected. I installed Malewarebytes, which found more than 2100 malewares & 7 Trojan horses...

  I used the factory at the same time restore within Windows 8 boot, & of course, it works but will not validate Windows 8 once it ends. I even tried to clear cmos without result. He can simply read the product ID key encrypted from the UEFI bios.

  I could go in another (horrible) story about a third out of the seller of the security assistance Acer references on their site, but in reality what good it would do at this point?

  Does anyone have a solution for this?

  Thanks in advance for your time, review, & effort!

  Kind regards

• Do not remember the WPA key. Other computers on the network

  I don't remember my WPA key and reset isn't exactly an option since I have other computers already configured for the existing key. I don't mind reset other computers as well if I knew for sure that it works. However, there is a discrepancy between the length of the WPA key on my Linksys (indicated as asterisks-33) and the length of the WPA key shown on the laptop of my wife (indicated as asterisks-63).

  I am trying to add a Wii to my network. Our router is currently not broadcasting the SSID, but I typed the name of the router in the Wii in any case. (She even will be able to find a network that is not broadcasting its SSID?).

  I also added the Wii MAC address to the list of trusted computers.

  Regarding the password, I considered to change but I'm worried I might spoil my wife configuration.

  When I go into my wireless settings, I see that I use a WPA TKIP encryption which is 33 characters long. However, when I go into the configuration of the network on my wife's computer, she says that his encryption key is 63 characters (WPA - PSK TKIP). Why the keys of different length?

  Is it possible to change the encryption key on the router to something I'd remember? If so, that will enter my wife's computer? Wouldn't make sense that what I typed in the settings wireless of Linksys (33 characters) would be the same as mine rather than 63 characters?

  I'm so confused.

  Any help?

  First, the County of asterisk is meaningless.  Even the number of characters in your password is a secret, so all good programmer who wrote your wireless network card driver shouldn't have a number of astrerisk which corresponds to your password.

  Set your "broadcast SSID" "enabled."  Do you really think someone will lose hundreds (or thousands) of hours of time to break your password, just enter a router WPA?  As long as you use WPA or WPA2 and a password, you shouldn't worry about your SSID broadcast.

  You can use any key (sometimes called password or password) you want, but all the keys (in router and all computers) will be the same.  Ideally you should use a strong password.

  Choose passwords (keys): you should never use a Word from the dictionary as a password. If you use a Word from the dictionary as a password, or WPA2 can be cracked in a few minutes. When you take your login password and key encryption (password or password), you must use a random combination of uppercase letters, lowercase letters and numbers letters, but no spaces. A connection password, must be 12 characters or more. WPA and WPA2 passwords must be less than 24 characters. Note: Your key, password or password should not be a space in it.

  Most individuals should have their routers defined so that "remote management" of the router is disabled. If you must have this option enabled, then your password needs to be increased to a minimum of 24 random characters.

  An additional problem is that Windows XP requires SP3 run WPA2 (WPA with AES =).

• My Hp Pavilion laptop 2244sa g6 does not come with the product key for windows8. Is this normal?

  Hello

  My Hp Pavilion laptop 2244sa g6 does not come with the product key for windows8. Is this normal? I can't see it anywhere, should I worry?

  Some laptops, like my Envy 17-3002ea loan, have the certificate of authenticity Windows hidden in the compartment where the hard drive and the battery are.  First try.

  Other portable latest and which may include yours, have the Windows license key encrypted in the BIOS.  There is a thread on the Microsoft communities that verifies that. The thread is worth reading.

  Hello

  The ssid of your wpa is vlan 20 and your wep is vlan 30.

  Your encryption config is as follows:

  VLAN 30 key 3 size 40 bit 7 2D8DA7E84856 transmit encryption keys
  encryption vlan 30 wep40 tkip encryption mode

  I would like to replace these lines with:

  VLAN 30 key 3 size 40 bit 7 2D8DA7E84856 transmit encryption keys

  encryption vlan 30 mandatory wep mode

  encryption vlan 20 tkip encryption mode

  'wep40 mode ciphers' is really for wep + dot1x, not static wep. And on top of that, you had both tkip and wep/dot1x on your vlan 30 has no meaning so much to me.

  I hope this helps.

• Is it possible to send Radius accounting packets with two different servers?

  Hello experts!

  I have dilemma I send info Radius accounting on two different servers for authentication of the dot1x. Here are the relevent config. However the switch just to send a copy on the first server in the server group...

  RADIUS AAA server Acct group
  ACCT-port of the server 172.17.1.1 auth-port 1812 1813
  ACCT-port of the server 172.17.1.2 auth-port 1812 1813

  accounting dot1x default start-stop broadcast group AAA Acct

  RADIUS-server host 172.17.1.1 auth-port 1812 acct-port 1813 key xxxxxx
  RADIUS-server host 172.17.1.2 auth-port 1812 acct-port 1813 key xxxxxx

  Is it possible to send two copies of two different servers? I tried the key word 'issue' in the aaa accounting command, but it does make a difference. What is doing? I can't find it in the manual...

  Thank you!

  Difan

  Difan,

  You must create two aaa server groups to operate. Allows the sending of accounting records to multiple AAA servers.  At the same time returns accounting records the first server in each group. If the first server is unavailable, the failover occurs using servers defined within this group.

  Accounting AAA broadcast configuration
  The following example shows the turn on broadcast accounting using the aaa accounting global command:

  RADIUS AAA server group isp
  Server 1.0.0.1
  Server 1.0.0.2

  AAA isp_customer radius server group
  Server 3.0.0.1

  AAA accounting network default start-stop broadcast group isp group isp_customer

  host server RADIUS 1.0.0.1
  host server RADIUS 1.0.0.2
  Server RADIUS key key1
  RADIUS-server host 3.0.0.1 key2 keys

  The broadcast keyword causes the start and stop accounting for dot1x connections to be sent simultaneously to the 1.0.0.1 group isp server and Server 3.0.0.1 in the isp_customer group. If 1.0.0.1 is unavailable, Server failover 1.0.0.2 occurs. If the 3.0.0.1 server is unavailable, no failover occurs because backup servers are not configured for the isp_customer group.

  Kind regards

• Difference on the installation disc and computer product key

  Hello

  Why is the product key on the different installation for Windows 7 Ultimate disc from that on my computer that verifies a genuine copy was installed?  In other words, the product key on the installation disc has a combination of letters and numbers.  However, the product key on my computer that verifies that you have a genuine copy of Windows 7 Ultimate installed has only numbers.

  Thank you in advance.

  MoPete

  The product ID is never really entered into the computer, what you have on the label is a 24-bit coded version which decodes the installation process to form the product ID.

  If you have already built a system by entering the 25 character key, you will see a small break after entering the key. This is the decoding of the key system and then check the type of product with the version of the software being installed.

  Also, be aware that if your system is a large manufacturer and shipped with Windows preinstalled, then the encrypted key can not match the label. If you use a utility such as magic jellybean keyfinder on a system, it can retrieve this key encrypted in the registry. This key is different from the label, because all systems supplied by the manufacturer with a particular version of Windows will have the same key. This avoids having them to enter a key on all of the PCs they do individually and do not have to be authenticated on the line.

• ISO product key?

  Hello.

  UH... Dv6 - 7267cl running Windows 8.1 ENVY

  LSS: My father-in-law fell for one of these scams of ransom of customer service. Some guy called, convinced him install the remote access software, is made or infecting him not by malware (now makes no difference), and when he refused to pay for them to 'fix' him locked using syskey. I understand that this is a very common scam.

  Point being that I was able to recover his files with a universal adapter for USB hard drive and am trying to re-setting up Windows after a clean install. Problem is when I try to activate it, it requires a product key, that I don't have. I got the link from iso for this thread:

  (Windows Vista, 7 and 8 ISO / Image files download links, where the link is not post)

  It is my understanding from his machine, the product number would suffice. Now, I read more about this thread and see something need to change the iso file before installation in order for this to happen. So, I have to start? Another cost to install? Because if this is the case, it would be nice if some mod could change the OP post to reflect the fact that, if this does not happen to other people.

  Hello:

  If the laptop comes with the W8 (specifications of product indicated for this), you cannot use a detail file install W8 because Microsoft is returned at the time where you must use the same type of installation media that the product key is for.

  For example: W8 OEM must be reinstalled with a set of recovery disks or W8 OEM installation media.

  So... your options as I see them are:

  1. see if you can reset the computer to its factory settings using the Recovery Manager program.

  See info below.

  http://support.HP.com/us-en/document/c03489643

  If method 1 does not work then...

  2. order a set of recovery disc W8 for this model by clicking on the link below and then click to expand the order recovery media line and then click on the blue button more details.
