Contents How to generate digital certificate using keytool How to generate digital certificate using DigiSigner (graphical interface) Generate digital certificate using keytool Keytool is a utility for generating and managing cryptographic keys and certificates. Keytool is a part of Java installation, so you need to have Java on your computer. This tutorial is a part of our DigiSigner tutorial and explains in detail how to generate digital certificates using keytool, key and certificate management tool. We also show how to do the same task using the graphical interface of our DigiSigner tool, tiny PDF viewer and signer. Sep 12, 2014 Use this method if you already have a private key that you would like to generate a self-signed certificate with it. This command creates a self-signed certificate (domain.crt) from an existing private key (domain.key): openssl req -key domain.key -new -x509 -days 365 -out domain.crt. In digital certification, CA (Certification Authority) is the third party individual, who issues certificates that are trustworthy to all the other parties involved in the communication. Certification authority issues the certificates, which contain a public key, certificate subject and the details about the authority itself. The G Suite Single Sign-On service accepts public keys and certificates generated with either the RSA or DSA algorithm. To use the service, you need to generate the set of public and private keys and an X.509 certificate that contains the public key. Once you have a public key or certificate, you would then need to register it with Google. Cryptographic key storage is hugely important in keeping your Digital Certificates safe from attack. With so many options, we wanted to give you the ultimate guide for your specific use case.

DigiCert and Microsoft are working together to improve how enterprises can seamlessly obtain high-assurance certificates and keep those certificates renewed by providing convenient access to SSL/TLS certificates and private key storage. Azure Key Vault customers can order DigiCert SSL Certificates directly from their Key Vault account through the CertCentral REST API. Certificates are automatically renewed, making sure that lapses in SSL/TLS security don't happen.

Microsoft knows that secure key management is vital to keeping your data safe in the cloud. With Azure Key Vault, you can store and encrypt your keys and passwords at rest on virtual HSMs (hardware security modules). The DigiCert integration with Key Vault allows you to order SSL/TLS certificates and store your certificates and their private keys there as well.

Link your Microsoft Azure Key Vault and DigiCert CertCentral accounts

First, you need an Azure account. Your Azure account includes the Key Vault for storing keys, passwords, etc.
Next, you need to activate your CertCentral account. This account is specifically set up for integration with your Azure Key Vault account.

*If you already have CertCentral account, contact your account manager or our support team. They can help make sure your account is set up for your Azure Key Vault account integration.

Instructions for getting started

To learn how to integrate your Azure Key Vault account to your DigiCert CertCentral account, see Azure Key Vault integration guide.

Overview

Cryptographic keys are strings of bytes that you combine with other data in specialized mathematical operations to enhance security. At the lowest level, this usually means participating in either encryption and decryption or digital signing and verification. You can use these basic operations directly, such as when you encrypt data before sending it through an insecure channel. You also use them implicitly, such as when you verify the digital signature on a certificate as a byproduct of a trust evaluation.

Keys vary based on the operations they support. For example, you use public and private key pairs to perform asymmetric encryption, whereas you use symmetric keys to conduct symmetric encryption. Similarly, one key might work for a 1024-bit RSA algorithm, while another might be suitable for a 256-bit elliptic curve algorithm. Use the functions in this section when you need to handle cryptographic keys.
