We’ll discuss cryptographic solutions including symmetric & asymmetric cryptography, hashing, and Azure services. This post is your guide to understanding these essential security measures.

Before diving in, let’s understand the importance of cryptography. It’s the art of protecting information by transforming it into unreadable format. It’s the backbone of secure communication in our digital age. Keep reading to explore different cryptographic methods.

✅ Symmetric cryptography

It’s fast, efficient, & great for large data volumes. Uses one key for both encryption & decryption. Common algorithms include AES, DES, 3DES, Blowfish & RC4. Symmetric encryption is used in Azure to efficiently encrypt and decrypt large amounts of data.

  • 🔽 AES: Advanced Encryption Standard, a symmetric block cipher that uses 256-bit keys to encrypt and decrypt data. It is used by Azure Storage Service Encryption, Azure Disk Encryption, and Transparent Data Encryption.
