ssl client certs

[ghost]

I wondered if you'd ever thought of supporting ssl client certs?

[tsenart]

What is the exact use case?

[ghost]

At the BBC we have a number of web services using SSL encryption (HTTPS) which the client can only communicate through with an SSL cert. JMeter and Tsung support such certification, but I am looking for a tool where I can write tests as code (not XML). I don't know enough about Go to add it in myself, but I intend to learn Go as I eventually want to contribute to an OS load-test tool.

[tsenart]

This functionality can be added relatively easily. I'll try to find the time to do it soon.

[ghost]

Many Thanks.

[tsenart]

@AidyLewis: Please download the latest release and let me know if it solves your problem.

[ghost]

Tested an endpoint without cert and I received a handshake failure in the results. Tried a P12 which gave a bad cert. converted p12 => pem with this command $ openssl pkcs12 -nodes -in cert.p12 -out cert.pem Again, I received a handshake failure.

using:
$ vegeta attack -duration=10s -rate=10 -targets=targets.txt -output=results.bin -cert=dev-cert.pem

I will try another .pem.

@AidyLewis

[tsenart]

Please include the inputs and outputs of your test runs. I suggest you run it as such:

echo "GET https://$HOSTNAME:$PORT" | vegeta attack -cert="$CERT" -duration=1s -rate=10 | tee results.bin | vegeta report

[ghost]

Hi,

I've attempted every conceivable way of converting a p12 to pem.

echo "GET https://api.stage.bbc.co.uk/locator/locations?order=importance&s=NW9%207NT&a=true" | vegeta attack -cert="dev-cert.pem" -duration=1s -rate=10 | tee results.bin | vegeta report 2014/09/09 17:30:56 Vegeta is attacking 1 targets in random order for 1s... 2014/09/09 17:30:57 Done!

[tsenart]

I am no expert in openssl but have you converted the certificate with the following? openssl pkcs12 -in cert.p12 -passin pass:password -out cert.pem

I presume you are able to connect to your server with openssl directly. Is that the case?

[ghost]

I have not forgotten about this, I'll re-attempt it again this afternoon.

[ghost]

Hi,

I have managed to curl on the dev svn repo which uses ssl

curl --cert dev-cert.pem --cacert ca.pem https://repo.dev.bbc.co.uk/load-test-team/cloud-load-test/trunk/bake-scripts/set-up

But still unable to use the vegeta cert switch:

echo "GET https://repo.dev.bbc.co.uk/load-test-team/cloud-load-test/trunk/bake-scripts/set-up" | vegeta attack -cert="dev-cert.pem" -duration=1s -rate=10 | tee results.bin | vegeta report

.... Error Set: Get https://repo.dev.bbc.co.uk/load-test-team/cloud-load-test/trunk/bake-scripts/set-up: remote error: handshake failure

Many Thanks

[tsenart]

Historically, there have been a number of issues with SSL code in the Go standard library. I can only attempt to solve this if your provide me with a certificate to debug with.

[ghost]

Hi @tsenart

It is impossible for me to provide you with a BBC cert, so the options are:

1) I create a web application that uses SSL certification and generate my own certs 2) Try to debug it myself.

I am learning Go at the moment, so I will have a go at debugging it myself (but it may take some time).

Many Thanks

Aidy

ps https://github.com/BBC/load-test-artefacts#vegeta

[ghost]

I see in your tests you have a cert.pem and a key.pem. Do I need to pass these files separately? Also do I not need a ca.pem?

[tsenart]

What do you mean, you have to pass these files directly? Have a look at http://golang.org/pkg/crypto/tls/#LoadX509KeyPair which would be used for a server.

[ghost]

It looks like we need to pass the public cert file and the private key separately. I currently have them bundled in one pem.

So wouldn't we need to do: -certs public-cert.pem, private-key.pem

Which then get passed into LoadX509KeyPair function?

Aidy

[pascalhofmann]

vegeta does not support ssl client certs. See https://golang.org/pkg/crypto/tls/#Config

    // Certificates contains one or more certificate chains
    // to present to the other side of the connection.
    // Server configurations must include at least one certificate.
    Certificates []Certificate

but vegeta sets:

    // RootCAs defines the set of root certificate authorities
    // that clients use when verifying server certificates.
    // If RootCAs is nil, TLS uses the host's root CA set.
    RootCAs *x509.CertPool

[tsenart]

@pascalhofmann: Contributions welcome! I'm quite busy the following weeks... :-)

[pascalhofmann]

Sorry, I'm very busy too. :(

I ended up deactivating the client certificate check for the load testing…

[ghost]

Is this just a matter of swapping the correct library in?

[tsenart]

@aidylewis: Would you mind building this branch and trying it out?

[ghost]

Hi @tsenart

Brilliant. I will test it out tomorrow, while I am at work.

[tsenart]

@aidylewis: Any luck?

[ghost]

I have been off sick with a cold. Will check first thing today. Many apologies.

[tsenart]

Oh please, don't apologize for that! Get well soon! On Tue, 17 Nov 2015 at 08:33, aidylewis notifications@github.com wrote:

What would you consider to be the best way to install a branch? I was thinking of go getting the master, switching to the cert branch, and then doing an install.

good man

I can connect through wget, but not through vegata

[tsenart]

OK, let's try to figure this out over chat: https://gitter.im/tsenart/vegeta

[ghost]

After @tsenart fix, I converted a p12 to a pem with the openssl command:

openssl pkcs12 -nodes -in /path/to/my/cert.p12 -out /pathto/my/cert.pem

This bundles the private key and public cert in the pem.

I then ran:

echo "GET https://whatever" | ./vegeta attack -duration=2s -cert=dev-cert.p12 -key=dev-cert.12 | tee results.bin | ./vegeta report

[tsenart]

@aidylewis: Can you download the pre release binaries again and try to use it without specifying the -key flag?

[ghost]

OK

[ghost]

Yep, works

Thanks for all you help @tsenart

[tsenart]

Great! :)

[tsenart]

And sorry for taking more than a year (!!!) to fix this.

[ghost]

Hi @tsenart

I am receiving this error on a site: "x509: certificate signed by unknown authority"

Do I need to pass a ca.pem as well?

[tsenart]

That means that site's certificate isn't signed by any of the trusted CAs in your system. If you open that site in your browser, is it trusted?

[ghost]

Good point. No.

[tsenart]

Well, then, what is the expected behaviour for you? Would you want a flag that disables certificate verification?

[ghost]

I was too shy to ask, but that'd be nice.

In return I could write a BBC technology blog that includes Vegeta if you were interested and I don't mind giving a recurring "tip" as a thank you for your work.

[tsenart]

Hehe, don't be shy! You didn't need to offer me such thing, but I won't say no :-) I'll try to have something ready by tomorrow.

Hi @tsenart

I cannot find your email on the internet. Mine is adrian dot lewis at bbc dot co dot uk.

[sattishv]

Even i am facing the same issue ."x509: certificate has expired or is not yet valid: current time". Tried accepting the certificates through browser to make it trusted but it didnt . Is the disable SSL verification option available in vegeta. Can you please calrify

[stephenwsun]

@sattishv I believe the flag that you need to disable SSL verification is insecure. Set -insecure=true and that should work for you.

[sattishv]

Thanks Will check disabling it
