Unable to load Private Key. (PEM routines:PEM_read_bio:no start line:pem_lib.c:648:Expecting: ANY PRIVATE KEY)
I have a .key file which is PEM formatted private key file. I didn't make this file but I got this from somewhere.
I wanted to see its MD5 hash with openssl tool like below command.
openssl rsa -in server.key -modulus -noout
But this generates below error.
unable to load Private Key

Here's some asn1parse of the .key file.
openssl asn1parse -in server.key

Is there anything more I can try?
Answer
Open the key file in Notepad++ and verify the encoding. If it says UTF-8-BOM then change it to UTF-8. Save the file and try again.
