An email is vulnerable at several different points along its journey. All organisations, irrespective of industry and size, use emails to exchange data and documents that may include financial information, customer contracts, employee information, and other forms of sensitive data. Cryptographic techniques can be used to ensure the safe transmission of an email. The longer a key is, the better security it provides for encrypting data and documents in various verticals such as banking, financial services, and healthcare. The length of a key must align with the algorithm that will use it, and most algorithms support a range of different key sizes.
Key learning objectives:
Understand the need for cryptography needed in modern email communications
Comprehend the significance of key length in encryption
Understand the 2 types of models used in modern email encryption
