IOS version that support 2048 bits certificate

Hello,
I need to update a 2504 Wireless Controller to a version that supports 2048 bits certificates.
I´m checking release notes for release 7.4.110.0 and I don´t see any information about a limitation in certification size (2048 bytes in my case).
Do you know any restriction about the certificate size in this or another version?
Thanks and Regards.
Iván.

2048 bit is supported on the WLC. I use it for WebAuth and 3rd party certificates as these vendors only issue 2048 these days.

I am trying to get my application (e-qip )"We did not detect that your web browser supports 128-bit high encryption.Have trouble "Continue" button below, you will need to upgrade your web browser to a version that supports 128-bit encryption"

I am trying to complete my TSA job application and it is a requirement to complete e-qip questions?

That website is using an old method of checking the encryption level a web browser is capable of, it mentions Netscape 6.x/7 which are like from 6 to 7 years ago. It looks like they're checking for a '''U''' in the User Agent string. That particular letter in the UA goes back to the days of export controls for encryption software, but those controls expired over 15 years ago. That letter has been virtually meaningless since then. <br />

You can fool that website into thinking that you are using an older version of Firefox with this extension. <br />
https://addons.mozilla.org/en-US/firefox/addon/user-agent-switcher/ <br />
Use this for a custom UA string that should work there:<br /> '''Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.18) Gecko/20110614 Firefox/3.6.18'''
Or just use IE for that one website.

Any JavaCard supporting 2048 bit RSA?

Hi all,
I am finding a java card that supports 2048-bit RSA. I know there are existing products in the market. However, they are black-box operating, e.g. process digital signature. What I need is PLAIN RSA computation - if there is a plain Java card, I can program it by myself.
I have found some vendor, however, it seems they don't provide such plain Java cards.
Anyone know if there is such a 2048-bit Java card?
Thank in advance.
Cheers,
Hue

Oh thanks!!!!!!!!!!!!!!
Would you please give more detail to me?
At the mean time, I am searching on the web!!~~

How do go back to a version that supports Real Player?

How do go back to a version that supports Real Player?

According to the instructions given on the Norton Community forum under "Other Norton Products/Comcast-Customers - Norton Toolbar Problem in Firefox 10", I have done everything necessary. And I do have a Norton toolbar (Safe Web and Identity Safe) when I open Firefox 10. As was mentioned in the previous posts here, you need to run manual LiveUpdate then reboot until you have version 5.2.0.13. Then reboot and run manual LiveUpdate again and reboot once more. One thing that I noticed is that Norton never told me that it had updated the patch for Firefox 10, so I didn't know. I guess if you have the toolbar when you run Firefox 10, then you have done it all.

Can't Windows 7 access an RD on Server 2012 that uses SHA512/2048-bit certificates

I have a Server 2012 R2 Remote Desktop that works fine if configured with the self-signed certs (SHA1/2048-bit), but not with certs from our internal CA.
With the self-signed certs, our remote clients can connect but of course get security warnings due to the untrusted certificates. The clients do trust our root CA, so we should be able to eliminate those by using certs from our internal CA instead.
However, when I do configure the Server 2012 R2 RD to use certs generated on our internal CA (SHA512/2048-bit) clients (Windows 7) cannot open RDP sessions. They get errors and on server event log contain:
(Source: Schannel; Event ID: 36874) [sic] An TLS 1.2 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The SSL connection request has failed.
(Source: Schannel; Event ID: 36888) A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 40. The Windows SChannel error state is 1205.
The strange thing is that if I connect from client on Server 2008 R2, it can open RDP session!!!
Thanks.

Hi,
Indicates by the event, it seems that the Cipher Suites use by the client are disabled on the server.
Please check if any Cipher Suites of TLS 1.2 are disabled on the server.

CS5.5 Air for iOs - Which iOs versions are supported?

Hi everyone,
I wanted to test the functionalities of the Cs5.5 exporter for iOS, by exporting a previous Flash game i made on my 2G iPod, with 4.2.1 iOs version installed.
Since i wouldn't want to pay for the iOS developer certificate just for trying, can anyone point out a solution for this?
Moreover, is anyone sure it's gonna work? I wouldn't wanna spend good money just for seeing the Flash exporter is no good for my device.
Suggestions?
Anyone tried on similar OS?
Thanks a lot
Iacopo

Ok, i managed to use a fake certificate (i know i shouldn't say that) just to check the feasability of a game on iOS and.... I found out that the exporter doesn't work on my iPod Touch 2G (iOs 4.2.1)!! It says the iPod is not supported!!
Any news on this?
Do i need to buy an iPhone 5 to test flash games? It sounds a little extreme....

Router platform and IOS version to support MPLS

I have few Cisco 2621 routers and one 3640 router, could I use these router to create a MPLS VPN lab? if so , what is the minimum IOS version required?
Thanks in advance.

The minimum hardware and software image tu support MPLS can be found at www.cisco.com/go/fn select search by feature and in the search box put MPLS (Multiprotocol Label Switching) there you can find the platform and IOS to support basic MPLS, but you need to consider the fact that supporting MPLS special features like AToM can only be supported on some 7200, 7500, 7600, 10000 and 12000, http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide_chapter09186a0080153e64.html#1030652

Ideally any feature set questions are answerable in Cisco Feature Navigator (http://www.cisco.com/go/fn).
The Secure Copy (SCP) feature provides a secure and authenticated method for copying router configuration or router image files. SCP relies on Secure Shell (SSH), an application and a protocol that provide a secure replacement for the Berkeley r-tools. So ideally you should be running crypto images (k9) which support SSH and hence SCP as well.
But following are some details about SCP, which may be helpful :
Feature Name
Releases
Feature Information
Secure Copy
12.2(2)T12.0(21)S
12.2(25)S
This feature was introduced in Cisco IOS Release 12.2(2)T.
This feature was integrated into Cisco IOS Release 12.0(21)S.

12.3(4)T
15.3(2)S
The Secure Shell Version 2 Support feature allows you to configure Secure Shell (SSH) Version 2 (SSH Version 1 support was implemented in an earlier Cisco IOS software release). SSH runs on top of a reliable transport layer and provides strong authentication and encryption capabilities. SSH version 2 also supports AES counter-based encryption mode.
The following commands were introduced or modified: debug ip ssh, ip ssh min dh size, ip ssh rsa keypair-name, ip ssh version, ssh.
Secure Shell Version 2 Client and Server Support
12.0(32)SY
12.3(7)JA
12.4(17)
The Cisco IOS image was updated to provide for the automatic generation of SNMP traps when an SSH session terminates.
SSH Keyboard Interactive Authentication
12.2(33)SXH3
12.4(18)
The SSH Keyboard Interactive Authentication feature, also known as Generic Message Authentication for SSH, is a method that can be used to implement different types of authentication mechanisms. Basically, any currently supported authentication method that requires only user input can be performed with this feature.
Secure Shell Version 2 Enhancements
12.2(50)SY
12.4(20)T
15.1(2)S
The Secure Shell Version 2 Enhancements feature includes a number of additional capabilities such as support for VRF-aware SSH, SSH debug enhancements, and DH Group 14 and Group 16 exchange support.
In Cisco IOS 15.1(2)S, support was added for the Cisco 7600 series router.
Note
Only the VRF-aware SSH feature is supported in Cisco IOS Release 12.2(50)SY.
The following commands were introduced or modified: debug ip ssh, ip ssh dh min size.

It´s thrue that there´s a MB that supports 64 bit and 32 bit processors?

can you confirm this?

DC

Although someone mentioned about the 865PE Neo3-F which maybe one but no one can confirm this as none of the manufacturers has brought it up yet but the fact that Prescott moving on to 64bit may be possible.

Where do I find the latest version that supports Win/ME - I am running V 2.0.0.20 on an old machine.

I am running an older version of Mozilla V 2.0.0.20 on an IBM Pentium III Processor w/ 256MB of RAM and Win/ME - is there a place where I can get a newer release of Firefox - but not the latest. The present Version 24 does not support this operating system. A certain website 'bright.com' does not recognize this version I am using as valid - stating my browser is 'older than dirt' (which it is) and to upgrade.

hello, sorry starting with firefox 3 support for windows ME was dropped, so you're already on the newest old version that will be running on your system.
if possible you should consider upgrading to a newer machine since windows ME and firefox 2 have reached their end of life a long time ago and are affected by countless security vulnerabilities which can be exploited...

Which is Adobe product to be used for developing iPAD(IOS) applications that support PDF edit on the

Question:
We would like to know if LiveCycle ES 8.0 supports development of applications for IOS devices like iPAD,...
Our requirement is to build applications that opens PDF on an iPAD, let the user edit and save the PDF.
If not, which other Adobe product does?
Thanks,
Murali

If you want to add text as comments, then a form created in Acrobat (Acroform) will work in Adobe Reader for iOS. It does not support forms created in LiveCycle Designer (XFA). There are also other PDF viewers that support Acroforms and commenting. So you don't need to create an application, just documents (PDF forms) that can be opened in an existing application (PDF viewer) that supports forms and commenting.
If you want to edit/add text that is part of the regular page contents of an existing PDF, I'm not aware of anything on iOS that does that and I don't think Adobe has anything that will help you develop an app that will.

Good day,
Hi, You need minimum sup-bootdisk:s3223-advipservicesk9_wan-mz.122-18.SXF7.bin IOS to enable INLINE mode on 6500 series.
as per my knowledge,
the latest IOS is
sup-bootdisk:s3223-adventerprisek9_wan-mz.122-18.SXF13.bin.
for IDSM-2, if u upgrade to Engine 2 IOS, U can get update with E2 signatures and also U can manage from New Management Console like Cisco IPS manager Express 6.1.
I hope this will satisfy.

TS1702 i have iphone 3g . i m using ios 4.2.1 . i want to install viber , skype, facebook and an english dictionary. i downloaded it but at the end it says that my ios version doesnot support the application. so how do i get these apps. please help

how do i get dictionary application in my iphone 3g running in 4.2.1 ios. and i want skype and viber and facebook as well. could anyone help

Since the iPhone 3G will only run iOS up to 4.2.1, if these apps require a higher iOS level, there is nothing that you can do.
There should be some dictionary apps in the App store that will run on iOS 4.2.1.
