Module: Azaion.Test.SecurityTest

Purpose

xUnit tests for the Security encryption/decryption functionality.

Public Interface

Test	Description
EncryptDecryptTest	Round-trip encrypt/decrypt of a ~1 KB string; asserts decrypted output matches original
EncryptDecryptLargeFileTest	Round-trip encrypt/decrypt of a ~400 MB generated file; compares SHA-256 hashes of original and decrypted files

Internal Logic

• EncryptDecryptTest: creates a key via Security.GetApiEncryptionKey, encrypts a test string to a MemoryStream, decrypts back, compares with FluentAssertions.
• EncryptDecryptLargeFileTest: generates a large JSON file (4M numbers chunked), encrypts, decrypts to a new file, compares file hashes via SHA256.HashDataAsync.

Private helpers:

• CompareFiles — SHA-256 hash comparison of two files
• CreateLargeFile — generates a large file by serializing number dictionaries in 100K chunks
• StringToStream — converts a UTF-8 string to a MemoryStream

Dependencies

• Security (encrypt/decrypt)
• StreamExtensions.ConvertToString
• FluentAssertions
• Newtonsoft.Json
• xUnit
