AES ECB Encryption in Go
AES ECB mode encryption, where each block of plaintext is encrypted independently, is a simple but potentially insecure encryption method. In Go, you can perform AES ECB decryption using the following code:
<code class="go">package main
import (
"crypto/aes"
"fmt"
)
func decryptAes128Ecb(data, key []byte) []byte {
cipher, _ := aes.NewCipher(key)
decrypted := make([]byte, len(data))
size := 16
for bs, be := 0, size; bs < len(data); bs, be = bs+size, be+size {
cipher.Decrypt(decrypted[bs:be], data[bs:be])
}
return decrypted
}
func main() {
key := []byte("YourEncryptionKey")
data := []byte("DataToBeEncrypted")
ciphertext := encryptAes128Ecb(data, key)
fmt.Println("Ciphertext:", ciphertext)
plaintext := decryptAes128Ecb(ciphertext, key)
fmt.Println("Plaintext:", plaintext)
}</code>Note that ECB mode is not considered secure for practical applications as it lacks diffusion and can be vulnerable to attacks like the "electronic codebook" attack. Therefore, it is generally recommended to use a more secure mode such as CBC.
