Today I had to set up something but I kept getting ssl errors. Turns out, thecertificate did not match the private key, because the private key file wasdamaged. After I copied the certificate all was good, so it might got damagedwhile
openssl commands give you the hash of the modulus of certificateand the private key. If those two don't match then they either do not below toeach other, or the file is damaged.
My private key is named
private.key and my certificate file is named
certificate.crt. Both are in PEM format.
openssl x509 -noout -modulus -in certificate.crt | openssl md5(stdin)= d238708c18b3c0d42994cfb61f060467
openssl rsa -noout -modulus -in private.key | openssl md5 (stdin)= 5dd148535fb0763926c285c83cb6b58
They don't match... This was the result after I did another
openssl rsa -noout -modulus -in private.key | openssl md5(stdin)= d238708c18b3c0d42994cfb61f060467
