</html><description>Introduction to Asymmetric Encryption The Problem with symmetric encryption Symmetric encryption is great for encrypting data when both the sender and receiver are in possession of the shared symmetric key. However this form of encryption requires the key to be shared before use. This is a problem on open networks such as the internet as&hellip;&nbsp;Read More &raquo;</description><thumbnail_url>https://learnlearn.uk/alevelcs/wp-content/uploads/sites/20/2022/03/asymmetric-key-encryption-a-level-cie-9618.png</thumbnail_url></oembed>
