Hi,
What I have:
- tls-certificate (x.509 format, pem encoded)
- within the tls-certificate -> public-key (rsa encrypted)
- corresponding private-key (pem encoded, rsa encrypted)
What I want:
- validate pem encoded private-keys // (something like 'openssl rsa -in
client.key -check' )
- validate key-pair (if private-key is matching certificate) // (something
like is key matching certificate running -> 'openssl x509 -noout -modulus
-in client.cert | openssl md5' == 'openssl rsa -noout -modulus -in
PRIVATEKEY.key | openssl md5')
What I tried:
*func *CheckKeyPair(clientcert, key string) error {
block, _ := pem.Decode([]byte(clientcert)) // decode pem
encoded tls certificate
cert,_ := x509.ParseCertificate(block.Bytes) // parse certificate
(get type x509.*Certificate)
fmt.Println(reflect.TypeOf(cert.PublicKey)) // print parsed
public-key from certificate (get type *rsa.PublicKey)
*return *nil
}
I fill this function with an the tls-certificate (type string) and
private-key (type string).
I've already started several experiments. That's why I haven't posted my
mischief yet.
I thought I would use this function, to validate the key-pair. ->
tls.X509KeyPair (https://golang.org/pkg/crypto/tls/#X509KeyPair)
Does anyone know how to move on?
Best,
A
