Is there a spec for CSR 'BEGIN' headers?
certreq, csr, openssl, pkcs#10
Solution
Take a look at RFC7468 for CSR headers and footers.
Problem
I've noticed a subtle difference in how OpenSSL and Microsoft `certreq` generate PKCS10 CSRs: OpenSSL: ``` -----BEGIN CERTIFICATE REQUEST----- ``` Microsoft `certreq`: ``` -----BEGIN NEW CERTIFICATE REQUEST----- ``` (and a footer with the same, except for END) The PKCS10 spec doesn't have any information on these headers / footers, so I suspect they're not part of the spec. I would like to be able to handle as many formats of CSRs as possible, so: Is there a spec for CSRs 'BEGIN' headers? Also: do other forms of CSR header exist? What do CSR generation tools that aren't openssl or certreq use?
