x509: certificate signed by unknown authority
mon...@gmail.com
As the subject suggests, I got this error when I call tls.LoadX509KeyPair().
In fact, it is one of my software users have this problem. I suggested
to do the following work:
openssl verify /path/to/cert.pem
I don't know if it is the correct way to check this problem. More
precisely, if openssl verify success, does it imply that
tls.LoadX509KeyPair() should not have the problem "x509: certificate
signed by unknown authority"?
Can anyone here help me to figure out a way to solve/locate the root of
the problem?

openssl verify /path/to/cert.pem success. But still, I got "x509:
certificate signed by unknown authority" error.
Any thought then?

Well. It would be better to provide more information.
0. At first, openssl verify failed
1. We found the certificate authority which should be a trusted authority.
2. We put its .pem file under /etc/pki/tls/certs
3. openssl verify success. But still, we got "x509: certificate signed
by unknown authority"
4. Then I use the following script to generate .crt:
!/bin/sh
#
# Convert PEM Certificate to ca-bundle.crt format
#
# Now this work with *BSD sed as well. fix by komar
test ! $1 && printf "Usage: `basename $0` certificate" && exit 1
# Friendly Name and Underline Friendly Name with equal signs
openssl x509 -in $1 -text -noout | sed -e 's/^
*Subject:.*CN=\([^,]*\).*/\1/ p;t c' -e 'd;:c' -e 's/./=/g'
# Output Fingerprint and swap = for :
openssl x509 -in $1 -noout -fingerprint | sed -e 's/=/: /'
# Output PEM Data:
echo 'PEM Data:'
# Output Certificate
openssl x509 -in $1
# Output Cettificate text swapping Certificate with Certificate Ingredients
openssl x509 -in $1 -text -noout | sed -e 's/^Certificate:/Certificate
Ingredients:/'
5. Append the output to ca-bundle.crt
6. Still, same error

Yes. That's exactly how we find where to modify the .crt file.
Just a quick reminder: I didn't encounter this problem, a user of my
program did. I asked him if he can find the file
"/etc/ssl/certs/ca-certificates.crt" (which is the first file listed in
the variable certFiles). He said "No". The only .crt file he found
listed in variable certFiles is /etc/pki/tls/certs/ca-bundle.crt (second
one). And it is where he append the certificate.
I didn't read his script, which, according to his description, is used
to convert .pem file to .crt file. However, I think it would be enough
to simply append .pem file to the .crt file without any conversion. I
suggested him to do so.
I'm not sure if I told him a correct way. Because of time difference, he
may not be able to reply my mail soon.

to access the server. Because it is a production server, it may even not
allow to change any code in go package.
He told me that the program runs correctly on his own computer. But
cannot work with instances from amazon ec2 because of certificate.
I am not able to reproduce the bug on my side. What I am trying to do is
to figure out what's going on there. It seems that he incorrectly used
the file format.
Here is the whole discussion we have about this issue:

Really appreciate your help!

Could you add debug prints to function AppendCertsFromPEM incrypto/x509/cert_pool.go to
see if the desired certificated is indeed parsed correctly?
That's the difficult part of the whole problem: I do not have permission to access the server. Because it is a production server, it may even not allow to change any code in go package.

Thank you very much, minux!

As the subject suggests, I got this error when I call tls.LoadX509KeyPair().
In fact, it is one of my software users have this problem. I suggested
to do the following work:
openssl verify /path/to/cert.pem
I don't know if it is the correct way to check this problem. More
precisely, if openssl verify success, does it imply that
tls.LoadX509KeyPair() should not have the problem "x509: certificate
signed by unknown authority"?
Can anyone here help me to figure out a way to solve/locate the root of
the problem?

I am able to reproduce the error with the following code and on ubuntu 12.01 TLS (latest ami on EC2)
Fabrizio Milo aka misto
package main
import (
"crypto/tls"
"net"
"log"
)
func main() {
conn, err := net.Dial("tcp", "gateway.push.apple.com:2195")
if err != nil {
log.Fatal(err)
}
client := tls.Client(conn, &tls.Config{})
err = client.Handshake()
if err != nil {
log.Fatal(err)
}
}
On my linux box I receive:
2012/06/28 23:15:16 x509: certificate signed by unknown authority
exit status 1
On my mac box (where it works)
I receive:
2012/06/28 16:14:49 remote error: handshake failure
My guess at this point is that there could be something funny inside
http://golang.org/src/pkg/crypto/x509/root_unix.go
initSystemRoots() , roots.AppendCertsFromPEM
In the mean time I solved by ignoring the SSL certificate when
connecting and it works.
Hope this helps.

The machines that present the error are running Linux
But what about the client machines that don't present the error, what is the OS?

Entrust root certificate that this site depends on is broken: it's not
marked as a CA certificate.
However, even with that fixed, I still get a handshake error. I'm
guess that's because I don't have the correct client-certificate?
If someone who knows about this server can confirm that it actually
solves the problem, then I'll have a ponder about whether we should
land the patch.

When is likely to see the patch applied to the main repository?
Thanks for the fast turn around on this problem and to the community
(dave, Patrick) for the support :)

specifically bypassing a check in their case. None the less, I feel
it's probably worth landing.
I expect that it'll land within a few days, but a Go 1.0.3 release may
take a couple of months.
