-# File encryption utilities
-
-Here are a couple of useful file 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.
-
-The included utilities are:
-
-* [file encryption](#file-encryption) utilities,
-* and [bitmap encryption](#bitmap-encryption) utilities.
-
-On older CPUs, you can run the utilities [using Intel SDE](https://github.com/egor-tensin/aesni#running-on-older-cpus).
-
-## File encryption
-
-### aes_encrypt_file.exe
-
-Encrypts a file using AES-128/192/256 in the specified mode of operation.
-
-#### Usage examples
-
-For example, to encrypt the plaintext `input.txt`
-
-* using AES-128 in ECB mode
-* with key `0x11111111111111111111111111111111`
-* and write the ciphertext to `output.txt`,
-
-run:
-
-    aes_encrypt_file.exe -a aes128 -m ecb 11111111111111111111111111111111 input.txt output.txt
-
-To encrypt the plaintext from `input.txt`
-
-* using AES-192 in OFB mode
-* with key `0x111111111111111111111111111111111111111111111111`
-* and initialization vector `0x22222222222222222222222222222222`
-* and write the ciphertext to `output.txt`:
-
-run
-
-    aes_encrypt_file.exe -a aes192 -m ofb 111111111111111111111111111111111111111111111111 22222222222222222222222222222222 input.txt output.txt
-
-### aes_decrypt_file.exe
-
-Decrypts a file using AES-128/192/256 in the specified mode of operation.
-
-#### Usage examples
-
-To decrypt the ciphertext from `input.txt`
-
-* using AES-128 in ECB mode
-* with key `0x11111111111111111111111111111111`
-* and write the plaintext to `output.txt`,
-
-run
-
-    aes_decrypt_file.exe -a aes128 -m ecb 11111111111111111111111111111111 input.txt output.txt
-
-To decrypt the ciphertext from `input.txt`
-
-* using AES-192 in OFB mode
-* with key `0x111111111111111111111111111111111111111111111111`
-* and initialization vector `0x22222222222222222222222222222222`
-* and write the plaintext to `output.txt`,
-
-run
-
-    aes_decrypt_file.exe -a aes192 -m ofb 111111111111111111111111111111111111111111111111 22222222222222222222222222222222 input.txt output.txt
-
-## Bitmap encryption
-
-These utilities were developed primarily to demonstrate the drawbacks of using ECB mode
-(namely, the fact that identical plaintext blocks get mapped to identical ciphertext blocks).
-This can be explicitly shown using 8-bit-per-pixel bitmaps:
-
-Plaintext BMP | Encrypted in ECB mode | Encrypted in CBC mode
-------------- | --------------------- | ---------------------
-![Plaintext butterfly](bmp/butterfly.bmp?raw=true) | ![Ciphertext butterfly in ECB mode](bmp/cipherfly_ecb.bmp?raw=true) | ![Ciphertext butterfly in CBC mode](bmp/cipherfly_cbc.bmp?raw=true)
-
-### aes_encrypt_bmp.exe
-
-Encrypts the pixels in a BMP image file, preserving the header.
-The usage is the same as for [aes_encrypt_file.exe](#aes_encrypt_fileexe).
-
-### aes_decrypt_bmp.exe
-
-Decrypts the pixels in a BMP image file, preserving the header.
-The usage is the same as for [aes_decrypt_file.exe](#aes_decrypt_fileexe).
