ColdFusion CFHTTP I/O Exception: peer not authenticated - even after adding certs to Keystore

A colleague of mine found the following after experiencing the same issue when connecting to a 3rd party.

We used the solution provided in the comment by Pete Freitag further down the page. It works, but I think should be used with caution, as it involves dynamically removing and adding back in a particular property of the JsafeJCE provider.

For the sake of archiving, here is the original content of Pete Freitag's comment:

I've narrowed this down a bit further, and removing the KeyAgreement.DiffieHellman from the RSA JsafeJCE provider (which causes the default sun implementation to be used instead) seams to work, and probably has less of an effect on your server than removing the entire provider would. Here's how you do it:

<cfset objSecurity = createObject("java", "java.security.Security") />
<cfset storeProvider = objSecurity.getProvider("JsafeJCE") />
<cfset dhKeyAgreement = storeProvider.getProperty("KeyAgreement.DiffieHellman")>
<!--- dhKeyAgreement=com.rsa.jsafe.provider.JSA_DHKeyAgree --->
<cfset storeProvider.remove("KeyAgreement.DiffieHellman")>

Do your http call, but pack the key agreement if you want:

<cfset storeProvider.put("KeyAgreement.DiffieHellman", dhKeyAgreement)>

I figured this out by using the SSLSocketFactory to create a https connection, which provided a bit more details in the stack trace, than when using cfhttp:

yadayadayada Caused by: java.security.InvalidKeyException: Cannot
build a secret key of algorithm TlsPremasterSecret at
com.rsa.jsafe.provider.JS_KeyAgree.engineGenerateSecret(Unknown
Source) at javax.crypto.KeyAgreement.generateSecret(DashoA13*..) at
com.sun.net.ssl.internal.ssl.DHCrypt.getAgreedSecret(DHCrypt.java:166)

Would be great if the exception thrown from ColdFusion was a bit less generic.

specific to coldfusion 8 with an webserver with modern ssl ciphers:

I use coldfusion 8 on JDK 1.6.45 and had problems with giving me just red crosses instead of images, and also with cfhttp not able to connect to the local webserver with ssl.

my test script to reproduce with coldfusion 8 was

<CFHTTP URL="https://www.onlineumfragen.com" METHOD="get" ></CFHTTP>
<CFDUMP VAR="#CFHTTP#">

this gave me the quite generic error of " I/O Exception: peer not authenticated." I then tried to add certificates of the server including root and intermediate certificates to the java keystore and also the coldfusion keystore, but nothing helped. then I debugged the problem with

java SSLPoke www.onlineumfragen.com 443

and got

javax.net.ssl.SSLException: java.lang.RuntimeException: Could not generate DH keypair

and

Caused by: java.security.InvalidAlgorithmParameterException: Prime size must be
multiple of 64, and can only range from 512 to 1024 (inclusive)
    at com.sun.crypto.provider.DHKeyPairGenerator.initialize(DashoA13*..)

    at com.sun.net.ssl.internal.ssl.DHCrypt.<init>(DHCrypt.java:107)
    ... 10 more

I then had the idea that the webserver (apache in my case) had very modern ciphers for ssl and is quite restrictive (qualys score a+) and uses strong diffie hellmann keys with more than 1024 bits. obviously, coldfusion and java jdk 1.6.45 can not manage this. Next step in the odysee was to think of installing an alternative security provider for java, and I decided for bouncy castle. see also http://www.itcsolutions.eu/2011/08/22/how-to-use-bouncy-castle-cryptographic-api-in-netbeans-or-eclipse-for-java-jse-projects/

I then downloaded the

bcprov-ext-jdk15on-156.jar

from http://www.bouncycastle.org/latest_releases.html and installed it under C:\jdk6_45\jre\lib\ext or where ever your jdk is, in original install of coldfusion 8 it would be under C:\JRun4\jre\lib\ext but I use a newer jdk (1.6.45) located outside the coldfusion directory. it is very important to put the bcprov-ext-jdk15on-156.jar in the \ext directory (this cost me about two hours and some hair ;-) then I edited the file C:\jdk6_45\jre\lib\security\java.security (with wordpad not with editor.exe!) and put in one line for the new provider. afterwards the list looked like

#
# List of providers and their preference orders (see above):
#
security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider
security.provider.2=sun.security.provider.Sun
security.provider.3=sun.security.rsa.SunRsaSign
security.provider.4=com.sun.net.ssl.internal.ssl.Provider
security.provider.5=com.sun.crypto.provider.SunJCE
security.provider.6=sun.security.jgss.SunProvider
security.provider.7=com.sun.security.sasl.Provider
security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI
security.provider.9=sun.security.smartcardio.SunPCSC
security.provider.10=sun.security.mscapi.SunMSCAPI

(see the new one in position 1)

then restart coldfusion service completely. you can then

java SSLPoke www.onlineumfragen.com 443 (or of course your url!)

and enjoy the feeling... and of course

what a night and what a day. Hopefully this will help (partially or fully) to someone out there. if you have questions, just mail me at info ... (domain above).

Did you add it to the correct keystore? Remember that ColdFusion uses it's own Java instance. I spent several hours on this once before remembering that fact. The one you want is at somewhere like /ColdFusion8/runtime/jre/lib/security/
