84 TopicsAutomating ACMEv2 Certificate Management on BIG-IP
While we often associate and confuse Let's Encrypt with ACMEv2, the former is ultimately a consumer of the latter. The "Automated Certificate Management Environment" (ACME) protocol describes a system for automating the renewal of PKI certificates. The ACME protocol can be used with public services like Let's Encrypt, but also with internal certificate management services. In this article we explore the more generic support of ACME (version 2) on the F5 BIG-IP.2.6KViews7likes7CommentsAS3 w/ certificates and renewals..
So, I found myself in a little bit of a quandary with the use AS3 declarations to deploy our F5 configurations for our services. So to create a virtual server with SSL certificate and profiles, and the nine-yards, you need to have as part of your AS3 declaration: SSL certificate (key and cert), that populate the profile, that then populates the profile section within the virtual server. So far so good... Now, the certificate has a TTL (if you will), and needs to be renewed. In the past, I had a Python script that goes through the F5 using REST API to find expiring certificates and get new certs and updates the configuration. That worked just fine, and I have adapted that to be used on our new F5s using partitions/tenants, and it works. Unfortunately is also breaks the one source of truth (AS3), so if I go make a change to an AS3 declaration to make pool member or other configuration changes, and I then redeploy the AS3 declaration, then the OLD certificate if put back into play (which could be expired) and the service goes down. Has not happened yet, because this FUBAR situation popped into my head. ..and that is my quandary... How do I redeploy configurations and have it ignore the certificate and profile stanzas in AS3 declaration - so it does not redeploy an old and possibly expired certificate? One may think .. well update the declaration with the updated certificate. Not as easy as one may think. I would have to do this for any declaration that I want to modify, not a easy task.. log-into the F5, fetch the new PEMdata for the certificate and key, update the declaration, and then deploy it. In some AS3 declarations, I am defining multiple environments for a service, and there might be up to 5 different certificate/key pairs that I would need to update prior to redeploying .. ugh! I am in a pickle. Thoughts? The only solution that I have been able to conjure up in my head is additional automation and scripting that would automatically update the AS3 declarations when a certificate is renewed, which makes sense .. just have no idea how to go about this just yet. Hoping there are other alternatives?!Solved206Views0likes6Commentsserverssl cipher suites
Hi, Is there an easier way to know what are the cipher suites that the backend server (pool member) can support? I have read an article but it requires to create a script. I know there is openssl but this will only show the cipher that the backend server used to communicate back with F5. So I was thinking like if from F5 perspective will it be able to perform an sslscan what are the available ciphers suites the backend server can support? Thanks, and regards, Rechie402Views0likes2CommentsMissing Certificate after redirect
We have a requirement for any calls coming into https://abc.comto be redirected to Azure APIM https://apim-xyz.com/api A simple following rule has been setup in F5 for calls coming intohttps://abc.com when HTTP_REQUEST { HTTP::respond 307 Location "https://apim-xyz.com/api" } But the problem we are facing is with client certificate. After the redirect, the client certificate is no longer available and new URL"https://apim-xyz.com/api"is not able to validate the request. We have no control over the client. We can control F5, redirect and server. Any help would be greatly appreciated.513Views0likes4CommentsTrouble applying GoDaddy certificate to a virtual server
I have created a few virtual servers and applied certs. They work just fine because they are using our internal CA. I have one now that uses a GoDaddy cert. I was provided a GoDaddy pfx file. I imported the cert and key without issues. I created the SSL profiles. In the CLientSSL profile, I chose the newly imported GoDaddy cert for Certificate, Key and Chain. I added the profile to the virtual server. When I open the virtual server in any browser, I get "The site can't be reached". Using FireFox, I get the error, "Error code: PR_CONNECT_RESET_ERROR". Because it's not an invalid cert error, I can't easily troubleshoot. Am I doing something that is glaringly wrong?Solved3.4KViews0likes18CommentsProvision IOS profile for Exchange ActiveSync with client certificate authentication
Problem this snippet solves: If you need to use client certificate authentication for ActiveSync services on IOS, you need to deploy custom profiles through a Mobile Device Management. MDM is maybe a little bit too much to achieve only this feature. The irule below provide necessary materials to provision a certificate and an exchange profile on IOS. Tested successfully on IOS 9. We use SCEP protocol for certificate enrollment. How to use this snippet: You need to define a Virtual Server and an access profile to publish ActiveSync. Then, you need to assign the irule on the Virtual Server. The certificate is retrieved using SCEP protocol on a Microsoft ADCS 2012 R2. The SCEP url should be changed in the Exchange payload. We configured APM to protect the access to this service and retrieve attributes from Active Directory but you can change the irule code to retrieve information and protect the service in a different manner. When a user reach /enroll uri with Safari browser, the provisioning process starts. /!\ I provide an IOS payload as example, but you need to modify it to fit your environment and save it as an ifile. Settings that need to be changed in the xml payload : <string>HOST.DOMAIN.COM</string> : Activesync FQDN <string>DOMAIN-Issuer-CA</string> : Issuing CA Name (if exists otherwise related code should be removed) <data>CERTIFICATE</data> : X.509 certificate in Base64 for Issuing CA <string>DOMAIN-Root-CA</string> : Root CA Name <data>CERTIFICATE</data> : X.509 certificate in Base64 for the Root CA <string>DOMAIN</string> : Organization name to be present in the user certificate <string>http://scep.domain.com/scep</string> : SCEP url External links Github : github.com/e-XpertSolutions/f5 Code : 68654 Tested this on version: 11.5799Views0likes1CommentAutomate import of SSL Certificate, Key & CRL from BIG-IP to BIG-IQ
The functionality to automate the import of SSL cert & key from BIG-IP to BIG-IQ is available in the product starting BIG-IQ 7.0 and above. This script should not be used on BIG-IQ 7.0+ as it has not been tested on those versions. This script will import all supported SSL Certificate, Key & CRL that exist as unmanaged objects on this BIG-IQ which can be found on the target BIG-IP. Steps performed by the script: Gather certificateand key metadata (including cache-path) from BIG-IPs Download certificate and key file datafrom BIG-IPs Upload certificateand key file data to BIG-IQ Prerequisite:Discover and import LTM services before using this script.The target BIG-IP will be accessed over ssh using the BIG-IP root account. Installation:The script mustbe installed in BIG-IQ under /shared/scripts: # mkdir /shared/scripts# chmod +x /shared/scripts/import-bigip-cert-key-crl.py Command example: # ./import-bigip-cert-key-crl.py <big-ip IP address> Enter the root user's password if prompted.

Unable to establish iQuery between bigip devices. Connectivity is in place but failing with: SSL error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed I take this to be a certificate chain failure. The device certificates have been added to both DNS > GSLB > Servers > Trusted Server Certificates and System > Cert Mgmt > Device Cert Mgmt > Device Trust Certs. Yet, still no joy, running openssl confirms trust issues. Device certs are issued by a 2 tier PKI (intermediary and root). Big IP is 13 HF 2. Any suggestions? Is it common place to be using internal certs here?481Views0likes1CommentHow to Create a CSR in Powershell/iControl using an Existing Key
Hello, I am trying to automate CSR creation on the BigIP with iControl/Powershell. I can easily create new CSRs using new keys, but I can't figure out how to generate a CSR using an existing key. We need to do this so that we can update our SAN certs without invalidating the existing Certificate/key pair while we process the request with our provider. I use this to create a new key for a brand new CSR/Certificate request ... $CSRKey = New-Object -TypeName iControl.ManagementKeyCertificateKey_v2; $CSRKey.id = 'www.sitename.com'; $CSRKey.key_type = 'KTYPE_RSA_PUBLIC'; $CSRKey.bit_length = 2048; $CSRKey.security = 'STYPE_NORMAL'; ... but I can't find any functions in the iControl Reference Wiki to grab an existing key to use for the CSR. Can anyone point me in the right direction? Thanks!, Sean361Views0likes1Comment
