Summary by CodeRabbit

• Chores

  • Removed CryptoJS dependency and associated type definitions from the project.

• Tests

  • Updated authentication cryptography tests with predefined test data samples.
  • Refactored test cases to validate decryption using fixed ciphertext inputs.

Walkthrough

The changes remove the crypto-js package and its TypeScript type definitions from the project dependencies. Correspondingly, the test file is updated to remove CryptoJS imports and replace dynamic compatibility tests with static assertions. Two hardcoded ciphertext constants (legacyCiphertext and deterministicCiphertext) are introduced, and the test cases are refactored to verify decryption of these fixed inputs rather than testing encryption/decryption compatibility between different cryptographic implementations.
