+# Block encryption utilities
+
+Here are a couple of useful block encryption utilities built on top of the library.
+Each of the utilities accepts `--help` flag, which can be used to examine utility's usage info.
+
+On older CPUs, you can run the utilities [using Intel SDE](https://github.com/egor-tensin/aesni#running-on-older-cpus).
+
+## aes_encrypt_block.exe
+
+Encrypts 16-byte blocks using AES-128/192/256 in the specified mode of operation.
+
+### Usage examples
+
+For example, to encrypt
+
+* the plaintext block `0x00112233445566778899aabbccddeeff`
+* using AES-128 in ECB mode
+* with key `0x000102030405060708090a0b0c0d0e0f`,
+
+run:
+
+    aes_encrypt_block.exe -a aes128 -m ecb 000102030405060708090a0b0c0d0e0f 00112233445566778899aabbccddeeff
+
+To encrypt
+
+* the plaintext block `0x00112233445566778899aabbccddeeff`
+* using AES-192 in OFB mode
+* with initialization vector `0x22222222222222222222222222222222`
+* and key `0x000102030405060708090a0b0c0d0e0f101112131415161718`,
+
+run:
+
+    aes_encrypt_block.exe -a aes192 -m ofb 000102030405060708090a0b0c0d0e0f101112131415161718 22222222222222222222222222222222 00112233445566778899aabbccddeeff
+
