ValueError If the signature algorithm is undefined. Return a <= b. Computed by @total_ordering from (a < b) or (a == b). Our P12 file can contain a maximum of 10 intermediate certificates. If the named curve is not supported then ValueError is raised. This can happen for a, The split method is used to split a string based on a specified delimiter. First, generate a private key and the certificate signing request (CSR) in the rootca directory. chain. The first item needed is a Certificate Signing Request (CSR), see Generating a Certificate Signing Request (CSR) for details. Tip: if you want to generate the Private key and CSR code in another location from the get go, skip step 3.1. and replace the openssl part of the command with *OpenSSL base folder*\bin\openssl.exe: *OpenSSL base folder*\bin\openssl.exe req -new -newkey rsa:2048 -nodes -keyout *Some path*\server.key -out *Some path*\server_csr.txt.
