Generate Rsa Public Private Key With Cert

Posted By admin On 17.04.20

Git windows create ssh key. Jul 09, 2019 The Private Key is generated with your Certificate Signing Request (CSR). The CSR is submitted to the Certificate Authority right after you activate your Certificate. The Private Key must be kept safe and secret on your server or device, because later you’ll need it for Certificate. RSA key is a private key based on RSA algorithm. Private Key is used for authentication and a symmetric key exchange during establishment of an SSL/TLS session. It is a part of the public key infrastructure that is generally used in case of SSL certificates.

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

Create Rsa Public Key

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.
