I am writing an Internet Draft that will include transmission of a CSR,
so I need to reference the proper source. No more sloppy, "well it
Some digging said it is in PKCS#10 - CSR. But I did not stop with that.
A bit more googling lead me to RFC 4211...
When I create a CSR with:
openssl req -config openssl-intermediate.cnf\
-key ./private/client.key.pem \
-subj "$DN" -new -out ./csr/client.csr.pem
What format is this? Are there better, more concise formats (e.g. DER?)
for transmission over constrained networks?
I can dump it with
openssl req -text -noout -verify -in ./csr/client.csr.pem
But that does not really tell me the format, only what is in the cert.
