Hy Natxo,
check out the pkix [0] and asn1 [1] packages. You can try to parse the
DER encoded subject into RDNSequence.
[0]: https://golang.org/pkg/crypto/x509/pkix/#RDNSequence
[1]: https://golang.org/pkg/encoding/asn1/#Unmarshal
Spoiler:
This should work:
package main
import "fmt"
import "crypto/x509"
import "encoding/asn1"
import "crypto/x509/pkix"
func main() {
store, err := x509.SystemCertPool()
if err != nil {
panic(err)
}
subjects := store.Subjects()
for _, rawSubject := range subjects {
var subject pkix.RDNSequence
if _, err := asn1.Unmarshal(rawSubject, ); err != nil {
panic(err)
}
fmt.Printf("%+v\n", subject)
}
}
The unmarshal code is borrowed from https://stackoverflow.com/a/50640119
Cheers,
Michael

[go-nuts] [crypto/x509] SystemCertPool() print subjects of ca certs
hi,
as a learning exercise I would lke to loop through the system's certificate
authorities store, and get the subjects of each certificate authority.
I have this code:
package main
import "fmt"
import "crypto/x509"
func main() {
store, err := x509.SystemCertPool()
if err != nil {
panic(err)
}
fmt.Printf("%T\n", store)
subjects := store.Subjects()
fmt.Printf("%T\n", subjects)
for _, v := range subjects {
fmt.Printf("%T\n", v)
fmt.Println(string(v))
}
}
But I am getting a lot of gibberish.
There should be a better way to do this, but I obviously do not know it.
Thanks for any pointers.
