+
+================================VULNERABILITIES================================
+Vulnerability: CWE-327: Use of a Broken or Risky Cryptographic Algorithm
+Issue: The affine cipher is a very weak encryption algorithm that can be easily broken using frequency analysis or brute force attacks. It provides no real security and should not be used for any sensitive data.
+Solution: Use a strong, modern encryption algorithm like AES from the Python cryptography library instead of implementing weak ciphers from scratch. Ensure the encryption key is generated securely using a cryptographically secure random number generator.
+
+Vulnerability: CWE-259: Use of Hard-coded Password
+Issue: The encryption key parameters a and b are not derived from user input or a secure key generation process. Using hard-coded keys significantly weakens the security of the encryption.
+Solution: Generate the encryption key using a secure key derivation function like PBKDF2 from the Python cryptography library. The key should be derived from a user-provided password or passphrase, and a random salt should be used.
+
+================================================================================
+Here are the Pytest test scenarios for the provided `affine_cipher_encrypt` method:
+
+Scenario 1: Encryption of lowercase alphabetic characters
+Details:
+  TestName: test_affine_cipher_encrypt_lowercase
+  Description: This test verifies that the affine_cipher_encrypt function correctly encrypts lowercase alphabetic characters using the provided encryption parameters.
+Execution:
+  Arrange: Define a plaintext string containing lowercase alphabetic characters and the encryption parameters a and b.
+  Act: Call the affine_cipher_encrypt function with the plaintext, a, and b as arguments.
+  Assert: Check that the returned encrypted text matches the expected encrypted string.
+Validation:
+  This test is crucial to ensure that the core functionality of the affine_cipher_encrypt function works as expected for lowercase alphabetic characters, which is a fundamental requirement of the Affine Cipher encryption.
+
+Scenario 2: Encryption of uppercase alphabetic characters
+Details:
+  TestName: test_affine_cipher_encrypt_uppercase
+  Description: This test verifies that the affine_cipher_encrypt function correctly encrypts uppercase alphabetic characters using the provided encryption parameters.
+Execution:
+  Arrange: Define a plaintext string containing uppercase alphabetic characters and the encryption parameters a and b.
+  Act: Call the affine_cipher_encrypt function with the plaintext, a, and b as arguments.
+  Assert: Check that the returned encrypted text matches the expected encrypted string.
+Validation:
+  This test is important to ensure that the affine_cipher_encrypt function handles uppercase alphabetic characters correctly, maintaining the case sensitivity of the input text.
+
+Scenario 3: Encryption of mixed case alphabetic characters
+Details:
+  TestName: test_affine_cipher_encrypt_mixed_case
+  Description: This test verifies that the affine_cipher_encrypt function correctly encrypts a mixture of lowercase and uppercase alphabetic characters using the provided encryption parameters.
+Execution:
+  Arrange: Define a plaintext string containing both lowercase and uppercase alphabetic characters and the encryption parameters a and b.
+  Act: Call the affine_cipher_encrypt function with the plaintext, a, and b as arguments.
+  Assert: Check that the returned encrypted text matches the expected encrypted string, preserving the original case of each character.
+Validation:
+  This test ensures that the affine_cipher_encrypt function maintains the case sensitivity of the input text when encrypting a mixture of lowercase and uppercase alphabetic characters.
+
+Scenario 4: Encryption of non-alphabetic characters
+Details:
+  TestName: test_affine_cipher_encrypt_non_alphabetic
+  Description: This test verifies that the affine_cipher_encrypt function correctly handles non-alphabetic characters by leaving them unchanged in the encrypted text.
+Execution:
+  Arrange: Define a plaintext string containing non-alphabetic characters (e.g., numbers, punctuation) and the encryption parameters a and b.
+  Act: Call the affine_cipher_encrypt function with the plaintext, a, and b as arguments.
+  Assert: Check that the returned encrypted text matches the original plaintext, with non-alphabetic characters remaining unchanged.
+Validation:
+  This test ensures that the affine_cipher_encrypt function does not modify non-alphabetic characters, as they are not subject to the Affine Cipher encryption process.
+
+Scenario 5: Encryption with a = 1 (identity transformation)
+Details:
+  TestName: test_affine_cipher_encrypt_identity_transformation
+  Description: This test verifies that the affine_cipher_encrypt function correctly encrypts the plaintext when the encryption parameter a is set to 1, resulting in an identity transformation.
+Execution:
+  Arrange: Define a plaintext string and set the encryption parameters a to 1 and b to any valid value.
+  Act: Call the affine_cipher_encrypt function with the plaintext, a, and b as arguments.
+  Assert: Check that the returned encrypted text matches the expected encrypted string, which should be a shifted version of the plaintext based on the value of b.
+Validation:
+  This test ensures that the affine_cipher_encrypt function handles the case when a = 1, which represents an identity transformation in the Affine Cipher encryption process.
+
+Scenario 6: Encryption with empty plaintext
+Details:
+  TestName: test_affine_cipher_encrypt_empty_plaintext
+  Description: This test verifies that the affine_cipher_encrypt function correctly handles an empty plaintext string by returning an empty encrypted text.
+Execution:
+  Arrange: Define an empty plaintext string and set the encryption parameters a and b to any valid values.
+  Act: Call the affine_cipher_encrypt function with the empty plaintext, a, and b as arguments.
+  Assert: Check that the returned encrypted text is an empty string.
+Validation:
+  This test ensures that the affine_cipher_encrypt function handles the edge case of an empty plaintext string gracefully, returning an empty encrypted text without any errors.
+
+These test scenarios cover the core functionality, case sensitivity, handling of non-alphabetic characters, identity transformation, and the edge case of an empty plaintext string. They provide a comprehensive set of tests to validate the business logic encapsulated by the `affine_cipher_encrypt` function.

+================================VULNERABILITIES================================
+Vulnerability: CWE-20: Improper Input Validation
+Issue: The 'shift' parameter is not validated and could be provided as a negative value, potentially causing unexpected behavior or errors.
+Solution: Add input validation to ensure 'shift' is a non-negative integer within a reasonable range.
+
+Vulnerability: CWE-327: Use of a Broken or Risky Cryptographic Algorithm
+Issue: The Caesar cipher is a weak encryption algorithm that can be easily broken using frequency analysis or brute force methods.
+Solution: Use a strong, modern encryption algorithm from the Python cryptography library, such as AES or RSA, instead of the Caesar cipher for secure encryption.
+
+Vulnerability: CWE-259: Use of Hard-coded Password
+Issue: The 'shift' value used in the encryption is hardcoded. If this value is not changed, an attacker who obtains the code can easily decrypt the ciphertext.
+Solution: Generate a random 'shift' value for each encryption. Store the 'shift' securely and provide it as needed for decryption.
