Why? Is this just for the RSAPrivateKeyInfo?

[Ryan Hamilton, 2015/09/11 17:14:11]

The ProofSource that we implemented requires the key to be in pkcs8 format.

+try openssl pkcs8 \
+  -topk8 \
+  -outform DER \
+  -inform PEM \
+  -in out/leaf_cert.key \
+  -out out/leaf_cert.pkcs8 \
+  -nocrypt
+
+# Generate the leaf certificate to be valid from now to one year in the future.

Why?

Why not? :> Seemed like a convenient period. But if you have period you'd
prefer, I'm happy to do that.

+try openssl ca \
+  -batch \
+  -extensions user_cert \
+  -startdate `date -u "+%y%m%d%H%M%SZ"` \
+  -enddate `date -v+1y -u "+%y%m%d%H%M%SZ"` \
+  -in out/leaf_cert.req \
+  -out out/leaf_cert.pem \
+  -config ca.cnf
