-Creating Test Vectors
----------------------
-
-To create test vectors for a block cipher the following code may be used as a
-template:
-
-.. code-block:: python
-
-    import binascii
-
-    from cryptography.hazmat.backends.openssl.backend import backend
-    from cryptography.hazmat.primitives.ciphers import base, algorithms, modes
-
-
-    def encrypt(key, iv, plaintext):
-        cipher = base.Cipher(
-            algorithms.CAST5(binascii.unhexlify(key)),
-            modes.OFB(binascii.unhexlify(iv)),
-            backend
-        )
-        encryptor = cipher.encryptor()
-        ct = encryptor.update(binascii.unhexlify(plaintext))
-        ct += encryptor.finalize()
-        return binascii.hexlify(ct)
-
-
-    vector_file = open(
-        "tests/hazmat/primitives/vectors/ciphers/AES/OFB/OFBMMT128.rsp",
-        "r"
-    )
-
-    count = 0
-    output = []
-    key = None
-    iv = None
-    plaintext = None
-    ct = None
-    for line in vector_file:
-        line = line.strip()
-        if line.startswith("KEY"):
-            if count != 0:
-                output.append("CIPHERTEXT = {}".format(encrypt(key, iv, plaintext)))
-            output.append("\nCOUNT = {}".format(count))
-            count += 1
-            name, key = line.split(" = ")
-            output.append("KEY = {}".format(key))
-        elif line.startswith("IV"):
-            name, iv = line.split(" = ")
-            iv = iv[0:16]
-            output.append("IV = {}".format(iv))
-        elif line.startswith("PLAINTEXT"):
-            name, plaintext = line.split(" = ")
-            output.append("PLAINTEXT = {}".format(plaintext))
-
-    output.append("CIPHERTEXT = {}".format(encrypt(key, iv, plaintext)))
-    print("\n".join(output))
-
-The algorithm, mode, and vector_file loaded must be modified to fit on a case
-by case basis. Additionally, the IV must be truncated (if necessary) to the
-length of the block size.
-
-The output generated by this script **must** be verified against at least one
-other implementation. In the example above, the vectors were generated against
-OpenSSL's implementation, so they must be verified against an implementation
-such as ``CommonCrypto`` or ``Go``.
-
-Any vectors generated by this method must also be prefixed with the following
-header format (substituting the correct information):
-
-.. code-block:: python
-
-    # CAST5 CBC vectors built for https://github.com/pyca/cryptography
-    # Derived from the AESVS MMT test data for CBC
-    # Verified against the CommonCrypto and Go crypto packages
-    # Key Length : 128
-
-If official test vectors appear in the future the custom generated vectors
-should be discarded.
