# Generate Private Key and Certificate using RSA 256 encryption (4096-bit key) |
openssl req -x509 -newkey rsa:4096 -keyout privatekey.pem -out certificate.pem -days 365 |
# Alternatively, setting the '-newkey' parameter to 'rsa:2048' will generate a 2048-bit key. |
# Generate PKCS#12 (P12) file for cert; combines both key and certificate together |
openssl pkcs12 -export -inkey privatekey.pem -in certificate.pem -out cert.pfx |
# Generate SHA256 Fingerprint for Certificate and export to a file |
openssl x509 -noout -fingerprint -sha256 -inform pem -in certificate.pem >> fingerprint.txt |
# Generate SHA1 Fingerprint for Certificate and export to a file |
#openssl x509 -noout -fingerprint -sha1 -inform pem -in certificate.pem >> fingerprint.txt |
# FYI, it's best practice to use SHA256 instead of SHA1 for better security, but this shows how to do it if you REALLY need to. |
