Mar 03, 2020  These commands create the following public/private key pair: rsaprivate.pem: The private key that must be securely stored on the device and used to sign the authentication JWT. Rsapublic.pem: The public key that must be stored in Cloud IoT Core and used to verify the signature of the authentication JWT. OpenSSL can generate several kinds of public/private keypairs. RSA is the most common kind of keypair generation. /generate-encryption-key-with-diffie-hellman.html. Other popular ways of generating RSA public key / private key pairs include PuTTYgen and ssh-keygen.

OpenSSL Generate 4096-bit Certificate (Public/Private Key Encryption) with SHA256 Fingerprint
gencert.sh
# 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.
