This topic describes the most common situations that developers must address when providing cryptography functionality in their applications. Each scenario explains the task, describes a real-world situation where such a task might occur, and includes code that demonstrates how to use the Cryptography Application Block to complete the task. The scenarios are the following:

  • Encrypting a Secret. This scenario illustrates how you can use a symmetric algorithm provider to encrypt a secret.
  • Decrypting a Secret. This scenario illustrates how you can use a symmetric algorithm provider to decrypt a secret that has been encrypted.
  • Getting a Hash From Text. This scenario illustrates how you can generate a hash value from data.
  • Check Whether a Hash Value Matches Some Text. This scenario illustrates how you can compare plaintext data with a hash value previously generated from the data, allowing you to verify that the data has not been changed since the hash was originally generated.
