私はAES 128でopenssl.voidを使ってデータを暗号化したいと思うmain(void)unsigned char key = 0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0a、0x0b、0x0c、0x0d、0x0e、 0x0f; AESKEY.

AES - Advanced Encryption Standard (also known as Rijndael).

We'll walk through the following steps:
- Generate an AES key plus Initialization vector (iv) with
openssl
and - how to encode/decode a file with the generated key/iv pair
Note: AES is a symmetric-key algorithm which means it uses the same key during encryption/decryption.
Generating key/iv pair
We want to generate a 256
-bit key and use Cipher Block Chaining (CBC).
The basic command to use is openssl enc
plus some options:
-P
— Print out the salt, key and IV used, then exit-k
or-pass pass:
— to specify the password to use-aes-256-cbc
— the cipher name
Note: We decided to use no salt to keep the example simple.
C Openssl Generate Aes 256 Key Generator
Issue openssl enc --help
for more details and options (e.g. other ciphernames, how to specify a salt, …).
Encoding
Let's start with encoding Hello, AES!
contained in the text file message.txt
:
C Openssl Generate Aes 256 Keyboard
Decoding
Decoding is almost the same command line - just an additional -d
for decrypting:
Note: Beware of the line breaks
While working with AES encryption I encountered the situation where the encoder sometimes produces base 64 encoded data with or without line breaks..

Aes-256 Encryption
Short answer: Yes, use the OpenSSL -A
option.
