How to edit a digital certificate?

My Server VPN downloads a digital certificate for the VPN users. I think this cert has the wrong address for the server. How can I change the ip address of cert? Or how can I stop the VPN server to require that the cert? I think the problem is to change service providers IP and do not change the address of the server in the cert.

The IOS configuration guide covers certificates here. While you can create a new certificate self-signed on the router (usually used with https for the Web administration - see this setup guide), it is preferable to use an internal CA or 3rd party public CA.

To turn off, find where it is called in your configuration. 'show crypto CA certificates' will show you what certificates you have entered on the router. One of them should be shouted in the VPN configuration.

However, it is not just as simple as that. If they are used for authentication and you remove them, they must be replaced by something else - as a preshared key, reference to a database user (internal or external such as LDAP or AD), etc. It is therefore a non-trivial task. You can get an idea what it comes to certificates of installation correctly at this link.

If you are not comfortable with the CLI, you might want to simply set up a new VPN profile using the GUI of CCP. Here is a link to this regime.

  • How to attach a digital certificate on a document

    Hello

    I use Windows 8. I don't have any information about the *.dll files and I am not a programmer is. I'm supposed to create a document online. I need to attach this document with a digital certificate. To create the certificate I required to copy a dll file in the syswow64 folder, I did. I have who has been properly executed. This should have led to the creation of a certificate, but his does not. Any ideas?

    Thank you

    Who asked you to copy the DLL of your system folder and run it?  This looks very suspicious and malicious, and I would not be surprised to learn that you injected just a virus in your system.  What you say that you took are not required for the use of digital certificates.

  • How no one inspects a digital certificate?

    Hi people,

    I learned to inspect a program a digital certificate for some things (it was revoked, it has expired, which is the transmitter, etc.), but I don't know how to get a handle on the certificate to verify these things.

    I've been googling and try different things for a few days now, but I don't get really anywhere. The best I came up with that is that I might need to use classes in java.security.cert, but I don't know how to use them. I looked at the docs on them, but they don't help me too. It seems a bit to me like java.security.cert classes are aimed at creating a digital certificate and not to download from a remote server so that I can inspect.

    Someone had to do this? How should I do to download a digital certificate in order to inspect?

    I have a little thought that if I did a GET cfhttp request, I could recover the certificate to check among the variables returned by cfhttp, but appear not to be the case.

    Help, please! I'm really, really stuck and could use any help I can get.

    I am running ColdFusion 8 Standard Edition if that makes a difference.

    Thank you
    Chris

    You need to remove the "https://" your host name and use the root

    If the address, site: -.

    host name = "pks.experian.com";

    From there, you should be dumpable information about the ssl certificate.

    Experimentation is the key!

  • How can I validate a digital certificate for a DLL to a computer that is disconnected?

    We have a network of computers engineering which is isolated from the Internet for security reasons. New software that we just installed is based on .NET framework from the Microsoft, and we have finally mapped out horrible lag to a series of ports being open to Verisign and CyberTrust and discovered that some of the new dll have digital certificates that try to validate the system. How can I get around this without connecting the computers to the outside world? Is there something I can do on my end, or something I should ask the Publisher of the software?

  • How can I know the FULL domain name & names for the installation of a digital certificate Public in ISE?

    We are implemented a project with Cisco ISE; but comments Portal appears to users as a "untrusted site". For problems, a public digital certificate must be installed in Cisco ISE, so he can send it to users who enter the comments Web portal.

    Now... to sell me the certificate, VERISIGN needs to know settings ISE of the certificate, such as name of area COMPLETE, names subnames, etc... How can these parameters of ISE?

    Thaks a lot!

    This isn't an easy question to answer, there are a ton of variables to include

    Local web site Central Web Auth or Auth

    LWA, the WLC is the "man in the Middle" to the request of the customer for PSN (server nodes), the WLC takes the request webauth and resembles webauth then the redirect URL that you put in the WLC

    If the redirect webauth URL is https://ise01.mycompany.com:8443/guestportal/login.action, the WLC is a redirect but the virtual IP address comes in 1.1.1.1, who was as trustworthy or redirection complains, then you may have to get the public certificate for the fqdn of 1.1.1.1, and the comment server. You can create a CSR using openssl or you can just enter in ISE and create a CSR, but you can only set CN = ise01.mycompany.com and nothing else, as long you have a single NHP is good, but if you have several Ssnp, you need to change your CSR so that you have to use openssl to create CSR using a file openssl.cnf and then with openssl, you do the following:

    openssl req - new - nodes-out openssl.cnf omf-01 - ise04.csr - config

    You must do it the way I said above regardless of CWA or LWA, if you have more than one PSN, you must point to a FULL VIP domain name and then configure your DNS to answer for these host names. With LWA, you get virtual IP WLC involved 1.1.1.1, so you don't have to worry about getting a certificate for this, it is a cleaner installation, but you must always do all the rest. It must ensure that users of your guests have the opportunity to join the portal comments and be able to solve the given DNS the dns server that they have been configured with.

    Content of the file openssl.cnf:

    [req]
    nom_distinctif = req_distinguished_name
    req_extensions = v3_req
    default_bits = 2048

    [req_distinguished_name]
    countryName = name of the country (2-letter codes)
    countryName_default = en
    localityName = name of the locality (for example, City)
    organizationalUnitName = organizational unit name (for example, section)
    commonName = Common Name (eg, YOUR name)
    commonName_max = 64
    emailAddress = Email address
    emailAddress_max = 40

    [v3_req]
    keyUsage = keyEncipherment, dataEncipherment
    extendedKeyUsage = AutClient, serverAuth
    subjectAltName = @alt_names

    [alt_names]

  • How to match tunnel-group with auth ASA 8.2 and IPSec VPN Client using digital certificates with Microsoft CA

    Hello

    I set up a lab for RA VPN with a version of the ASA5510 8.2 and VPN Client 5 software using digital certificates with Microsoft CA on a Windows 2003 server. I did the configuration based on this document from Cisco's Web site:

    http://www.Cisco.com/en/us/partner/products/ps6120/products_configuration_example09186a0080930f21.shtml

    Now, the vpn works fine, but now I need to configure a tunnel-different groups so I can provide different services to different users. The problem I have now is that I don't know how to set it up for the certificate is the name of tunnel-group. If I do an ASA debug crypto isakmp I get this error message:

    % ASA-713906 7: IP = 165.98.139.12, trying to find the group through OR...
    % 3 ASA-713020: IP = 165.98.139.12, no group found by matching well payload ID: unknown
    % ASA-713906 7: IP = 165.98.139.12, trying to find the group via IKE ID...
    % 3 ASA-713020: IP = 165.98.139.12, no group found by matching well payload ID: unknown

    % ASA-713906 7: IP = 165.98.139.12, connection landed on tunnel_group DefaultRAGroup

    So, basically, when using certificates I connect always VPN RA only with the group default DefaultRAGroup. Do I have to use a model of different web registration for application for a certificate instead of the user model? How can I determine the OU on the user certificate so that match tunnel-group?

    Please help me!

    Kind regards

    You can use the group certificate mapping feature to map to a specific group.

    This is the configuration for your reference guide:

  • How to download adobe digital editions to my ipad?

    How to download adobe digital editions to my ipad?

    You can not.

    Install the Bluefire app and enter it on the same AdobeID you use on your PC.

    Apple likes to make difficult things you cannot use a file manager to move from the books to the iPad.

    You must do so indirectly, by Dropbox, iTunes, send you the book, or similar.

    Once they arrived at the iPad, open in Bluefire.

    With Dropbox, there will be a big message saying something like "cannot open this file."

    but it simply means that Dropbox may not display itslef.

    In the top right of the box window will be a drop down list which gives you options of what to open it with.

    For library books, install the Overdrive app.

    Which will allow you to download and read books from the library without the need of PC/Mac at all.

    Thanks in advance!

    Craig

    If your ISP uses self-signed certificates ask them when they intend to become a professional store. Free self-signed certificates are basically something that exists to allow analysis of configurations without fees to pay for certificates. This leaves a loophole for tight companies, generally jobs of MOM and dad, or firms, who are simply stretched to use the correct string of voting trust and pay for their certificates.

    Not properly issued SSL certificates requires no acceptance, that the issuer or someone higher in the chain of trust is pre approved by Mozilla. It is extremely poor security to allow users wont accept SSL certificates and they are not experts in these things and could easily appove a certificate that makes their raw text of communication to third parties.
    You are done better with unsecured connections, you're free of those signed. At least you know your vulnerable.

    However, if you go to the menu Tools > options > advanced > certificates and Tower of the verify option you could do better. They are not probably set up as they sign free. Other than the view certificates and remove all those that you already have for them.

  • AnyConnect & authentication digital certificate

    people

    I have a question about the authentication of users with digital certificates and name of user and password

    My ssl vpn works well but I have only one user so far

    my query is about how to manage certificates and additional users

    I'll add the users in the asa for local authentication but it is the certificates that I'm not sure

    can I use the same account in the certificate local user dbase, i.e. sslconnect and generate a new OTP for each user that I add to create the certificate or should I create a new account in the ACL user dbase for each user account that I create in AAA

    hope this isn't too complicated

    Thanks to anyone who takes the time to answer or read this

    greatly appreciated

    If you are authenticating using certificate, you must issue each user a different certificate for him/herself. The certificate is a unique certificate for each user. I would recommend that you have the user name as the certificate CN instead of a good "sslconnect" like CN, so you can distinguish different users.

    Hope that answers your question.

  • SQL to retrieve the specific attributes of an x 509 digital certificate

    I'm curious to know if there is a way to use SQL to retrieve the specific attributes of an x 509 digital certificate. I know how to make using openssl - no problem. But what happens if the pem file is stored in a datebase column and I need to extract the expiration date. Since the openssl command line, I can just do this to extract the date of expiry of the certificate:

    OpenSSL x 509 - noout - in certificate.pem - dates | grep notAfter | AWK-f = '{print $2} '.
    (retrieves only the dates | take only the line with the expiration date | print only the second column of the row delimited =)

    But if certificate.pem is stored in an Oracle database on the ground, how to achieve the same result? Y at - it something like "DBMS_OPENSSL"?

    I got to thinking of V$ PORTFOLIO in an Oracle database. Only columns here are CERT_ID, DN, serial_num, TRANSMITTER, KEYSIZE and STATE - no certificate, which suggests that it is stored elsewhere. As you can tell, I am new to this.

    Thanks for your help!

    You can use a small procedure stored Java to extract the required fields.
