Unable to load Private Key. (PEM routines:PEM_read_bio:no start...) Solved!

 

 Example!!

"""

# file server.pem

"""

server.pem: UTF-8 Unicode (with BOM) text

output "server.pem: UTF-8 Unicode (with BOM) text" means it is a plain text, not a key file. The correct output should be "server.key: PEM RSA private key".

Use below command to remove illegal characters:

tail -c +4 server.pem > serverFixed.key

Verify a private key matches an certificate:

openssl x509 -noout -modulus -in server.crt | openssl md5
openssl rsa -noout -modulus -in server.key | openssl md5
openssl req -noout -modulus -in server.csr | openssl md5
