-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.
+After you've [built](https://github.com/egor-tensin/aesni#building) the block encryption/decryption utilities, you can verify the implementation either manually or automatically using test vectors.
 
 ## Manually
 
-The basic utilities have uniform interfaces.
-For the ECB mode of operation, the usage is follows:
+The block encryption/decryption utilities have uniform interfaces.
+For the ECB mode of operation, the usage is:
 
-    aesNNNecb_encrypt.exe KEY [PLAIN...]
+    aesNNNecb_encrypt_block.exe KEY0 [PLAIN0...] [-- KEY1 [PLAIN1...]...]
 
 and
 
-    aesNNNecb_decrypt.exe KEY [CIPHER...]
+    aesNNNecb_decrypt_block.exe KEY [CIPHER...] [-- KEY1 [PLAIN1--]...]
 
-For the modes of operation involving initialization vectors (CBC, CFB, OFB, CTR, etc.),
-use the utilities like this:
+where `NNN` is either `128`, `192` or `256`.

 ## Using test vectors

-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:
+The test scripts are written in Python 3, hence you need to be able to run Python 3 scripts in order to use them.
+The scripts have uniform interfaces: they accept a path to the directory with the block encryption/decryption utilities and allow to run them [using Intel SDE](https://github.com/egor-tensin/aesni#running-on-older-cpus).
+They also write log files with a short summary at the end.
+In general, each scripts counts the number of tests that failed, succeeded, caused an error, and the tests that were skipped.
+You must therefore make sure that
 
-    python 800-32a.py -r C:\build\test\Debug
+* no errors occured while running the tests,
+* all the tests succeeded,
+* and the skipped tests were skipped for a good reason.
