The issuer certificate of a looked up certificate could not be found. : /CN=reidmachine.partyĮrror 20 at 0 depth lookup:unable to get local issuer certificateĢ X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT: unable to get issuer certificate $ openssl verify -CApath /System/Library/OpenSSL/certs Where is the certificate signed by the SSL certificate just added to the Keychain Access app.

Testing installed certificate authority on Mac $ openssl verify -CApath /System/Library/OpenSSL/certs You should see new entries that include the name of the certificate authority that signed the certificate. I left it empty, and it seemed to be okay with that.

OS X requires a password on the key file. $ openssl pkcs12 -export -in -inkey -out certkey.p12 $ openssl pkcs12 -export -in pem-certificate-file -nokeys -nodes -out cert.p12 $ openssl pkcs12 -export -in pem-certificate-file -inkey pem-key-file -out certkey.p12 If the key and certificate files are separate:

$ openssl pkcs12 -export -in pem-certificate-and-key-file -out certkey.p12 pem format into PKCS12 format using this command: The CA file needs to be in PKCS12 format (yet another annoying decision to do weird non-standard things by apple engineers). Open Keychain Acces.app to add the certificate to the Mac keychain.

If they match, you are ready to install it. Openssl x509 -noout -fingerprint -in ca-certificate-file Calculate the fingerprint for the certificate and ensure it matches: Start by obtaining the CA fingerprint from a trusted source. pem CA file, which you will put into a file named with the certificate's own hash

If you are installing the certificate on Linux, you will need the.

If you are installing the certificate on a Mac, you will need to add it through the Keychain Access app.

To install an SSL certificate, see the OpenSSL guide to installing other people's certificates: Require and verify certificates against locally installed certificates.Ī self-signed certificate is the same as the certificate authority. If no certificate or an invalid certificate is presented, then it will drop the connection. Stunnel will require and verify certificates for every SSL connection. If the certificate is invalid, it will drop the connection. If the certificate valid, it will log which certificate is being used, and continue the connection. If no certificate is presented by the remote end, accept the connection. To turn on verification, set the verify option in the stunnel config file.

Verify certificates against pre-installed, "pre-trusted" root certificates (e.g., Verisign)īy default, stunnel does not verify SSL certificates, so clients will accept whatever SSL certificate they get from the server (or an attacker pretending to be the server).

Ask clients to install your certificate authority into their OpenSSL installation, so that they can verify the certificate.

Skip verification of certificates (not recommended if there is no authentication involved with the traffic being passed to stunnel, since a malicious actor could intercept and decrypt traffic).Using stunnel in a situation where you do not control the client gives you three options: To turn on verification, see Stunnel/Certificates#Verification section below. Verify certificates against locally installed certificates.Using stunnel in a situation where you control both the client and the server gives you two options: Generating a self-signed SSL certificate with openssl: RaspberryPi/SSH Stunnel#Generate Private Keys and Certificates for SSL Controlling both server and client Generating a signed SSL certificate with LetsEncrypt: see LetsEncrypt

The server will need a private key and an SSL certificate. See below, or "Generating stunnel certificate and private key" section of the stunnel howto: Server Certificates Generating a client SSL certificate is the same process as generating a server SSL certificate. While stunnel always requires a certificate (a pem file) to run, a dummy certificate is generated when stunnel is installed, and that dummy pem file can be used by the client since the server will probably not ask the client to present this certificate. Using stunnel in client mode (i.e., stunnel is not acting as an SSL server) means you (the client) probably don't need to present a valid certificate (to the server). The official stunnel howto has some useful (but confusing) information about certificates: Client Certificates 2.1.4 Testing installed certificate authority on Linux.2.1.3 Installing certificate authority on linux.2.1.2 Testing installed certificate authority on Mac.2.1.1 Installing certificate authority on mac.
