+This directory contains test certificates used for NBD's test suite.
+
+They are:
+
+* `client-key.pem` - client private key
+* `client-cert.pem` - client public key
+* `server-key.pem` - server private key
+* `server-cert.pem` - server public key
+* `ca-key.pem` - certificate authority private key
+* `ca-cert.pem` - certificate authority public key
+
+The `*.info` files are generated using the procedure below.
+
+Certificates can be made using the procedure at: https://qemu.weilnetz.de/qemu-doc.html
+using GnuTLS's certtool tool.
+
+Here's how:
+
+First make a CA:
+
+ # certtool --generate-privkey > ca-key.pem
+
+And give it a public key:
+
+ # cat > ca.info <<EOF
+ cn = Name of your organization
+ ca
+ cert_signing_key
+ EOF
+ # certtool --generate-self-signed --load-privkey ca-key.pem --template ca.info --outfile ca-cert.pem
+
+Next issue a server certificate:
+
+ # cat > server.info <<EOF
+ organization = Name of your organization
+ cn = server.foo.example.com
+ tls_www_server
+ encryption_key
+ signing_key
+ EOF
+ # certtool --generate-privkey > server-key.pem
+ # certtool --generate-certificate --load-ca-certificate ca-cert.pem --load-ca-privkey ca-key.pem --load-privkey server-key.pem --template server.info --outfile server-cert.pem
+
+Note the `cn` needs to match the hostname that nbd-client uses to connect (or the hostname specified with `-H` on the command line).
+
+And finally issue a client certificate:
+
+ # cat > client.info <<EOF
+ country = GB
+ state = London
+ locality = London
+ organization = Name of your organization
+ cn = client.foo.example.com
+ tls_www_client
+ encryption_key
+ signing_key
+ EOF
+ # certtool --generate-privkey > client-key.pem
+ # certtool --generate-certificate --load-ca-certificate ca-cert.pem --load-ca-privkey ca-key.pem --load-privkey client-key.pem --template client.info --outfile client-cert.pem
