crypt-aes

Implementation of the Advanced Encryption Standard (AES) cipher algorithm in GOLANG.

Created for educational purposes.

Usage

Creating a key

# Creates a 128-bit key
./crypt-aes --newkey -l 128
# Creates a 192-bit key (default)
./crypt-aes --newkey -l 192
# Creates a 256-bit key
./crypt-aes --newkey -l 256

Encrypting from standard input to standard output

cat originalfile | ./crypt-aes -e -k <key> > encryptedfile

If the key parameter is not informed, crypt-aes generates a random key and outputs it to standard error.

cat originalfile | ./crypt-aes -e > encryptedfile
Using key: 7db8c0f5ad323959f18d2f72024671a7ef3140bc266dedf6

Decrypting from standard input to standard output

cat encryptedfile | ./crypt-aes -d -k <key>

Encrypting from file

./crypt-aes -e -k <key> -i originalfile -o encryptedfile

Decrypt from file

./crypt-aes -d -k <key> -i encryptedfile -o originalfile
