How do I create a digital certificate using CrypTool?

Demonstration of digital signatures using CrypTool

1. First we need to generate a hash value of the document.
2. Next, generate a key pair.
3. After successfully generating keys, encrypt the hash value generated earlier.
4. We need to create a certificate associated with the RSA key.
5. Click on “store signature.”

Why do companies use cryptography?

Encryption safeguards your organization’s data and information from potential threats and ensures that even if an intruder gained access to your company’s sensitive information, it’s very unlikely they’ll be able to read any of it.
