Encryption is the process of converting data into a form that is unreadable by unauthorized parties. This is done by using a mathematical algorithm to scramble the data, and then using a key to unscramble it. The key is a piece of information that is known only to the sender and receiver of the encrypted data.
Decryption is the process of converting encrypted data back into its original form. This is done by using the same mathematical algorithm and key that were used to encrypt the data.
The OpenSSL migration guide provides details on the changes required to migrate to new versions of OpenSSL, specifically covering OpenSSL 3.0 & 3.1. Some of the main changes include: Further details can be found in the original documentation.
In the ever-evolving landscape of cloud computing, businesses increasingly rely on cloud services to drive agility, scalability, and cost-efficiency.
