+# Testing the implementation
+
+After you've [built](https://github.com/egor-tensin/aesni#building) the basic utilities,
+you can verify the implementation either manually or automatically using scripts.
+
+## Manually
+
+The basic utilities have uniform interfaces.
+For the ECB mode of operation, the usage is follows:
+
+    aesNNNecb_encrypt.exe KEY [PLAIN...]
+
+and
+
+    aesNNNecb_decrypt.exe KEY [CIPHER...]
+
+For the modes of operation involving initialization vectors (CBC, CFB, OFB, CTR, etc.),
+use the utilities like this:
+
+    aesNNNxxx_encrypt.exe KEY INIT_VECTOR [PLAIN...]
+
+and
+
+    aesNNNxxx_decrypt.exe KEY INIT_VECTOR [CIPHER...]
+
+For example,
+
+    > aes128ecb_encrypt.exe 000102030405060708090a0b0c0d0e0f 00112233445566778899aabbccddeeff
+    69c4e0d86a7b0430d8cdb78070b4c55a
+
+    > aes192cbc_encrypt.exe 000102030405060708090a0b0c0d0e0f1011121314151617 1032547698badcfe1032547698badcfe 00112233445566778899aabbccddeeff 00112233445566778899aabbccddeeff 00112233445566778899aabbccddeeff
+    92c01276b27eb8baaa3cabe2c661d4a8
+    d42bdf90c1a48221a92a5137c1445418
+    96248fca82fbefa31345ae7d8fb7933e
+
+On older CPUs, you can run the executables
+[using Intel SDE](https://github.com/egor-tensin/aesni#running-on-older-cpus).
+
+## Using test vectors
+
+### From NIST 800-38A
+
+You can test the implementation against the vectors from
+[NIST Special Publication 800-38A](http://csrc.nist.gov/publications/nistpubs/800-38a/sp800-38a.pdf)
+using `800-32a.py`.
+
+The script is written in Python 3, so you need to be able to run Python 3 scripts prior to testing.
+Then you can run the script, passing the path to the directory with the required `*_encrypt.exe` and `*_decrypt.exe` files like this:
+
+    python 800-32a.py -r C:\build\test\Debug
+
+On older CPUs, you can make the script run the executables
+[using Intel SDE](https://github.com/egor-tensin/aesni#running-on-older-cpus)
+using
+
+    python 800-32a.py -r C:\build\test\Debug -e
+
+I've tried to make the script output self-explanatory.
+The ultimate goal is to get `No mismatches detected!` in the final line.
