ecb
Warning Never use this in a production system. ECB mode is not secure.
This package implements the electronic codebook (ECB) block cipher mode, which is missing from Go's standard library.
It satisfies all the requirements of the crypto/cipher.BlockMode
interface.

Functions ¶
func NewDecrypter ¶
NewDecrypter returns a cipher.BlockMode which decrypts in electronic codebook mode, using the given cipher.Block.
Example ¶
package main
import (
"crypto/aes"
"fmt"
"github.com/clfs/ecb"
)
func main() {
key := []byte{
0x65, 0x61, 0x73, 0x74, 0x65, 0x72, 0x20, 0x65,
0x67, 0x67, 0x20, 0x66, 0x6f, 0x75, 0x6e, 0x64,
}
ciphertext := []byte{
0x18, 0x8d, 0xc8, 0xb9, 0x28, 0xae, 0x0a, 0x13,
0xb0, 0xe9, 0xab, 0x01, 0x12, 0x7f, 0xd3, 0x41,
}
block, err := aes.NewCipher(key)
if err != nil {
panic(err)
}
mode := ecb.NewDecrypter(block)
plaintext := make([]byte, len(ciphertext))
mode.CryptBlocks(plaintext, ciphertext)
fmt.Printf("%s\n", plaintext)
}
Output: exampleplaintext
func NewEncrypter ¶
NewEncrypter returns a cipher.BlockMode which encrypts in electronic codebook mode, using the given cipher.Block.
Example ¶
package main
import (
"crypto/aes"
"fmt"
"github.com/clfs/ecb"
)
func main() {
key := []byte{
0x65, 0x61, 0x73, 0x74, 0x65, 0x72, 0x20, 0x65,
0x67, 0x67, 0x20, 0x66, 0x6f, 0x75, 0x6e, 0x64,
}
plaintext := []byte("exampleplaintext")
if len(plaintext)%aes.BlockSize != 0 {
panic("plaintext is not a multiple of the block size")
}
block, err := aes.NewCipher(key)
if err != nil {
panic(err)
}
mode := ecb.NewEncrypter(block)
ciphertext := make([]byte, len(plaintext))
mode.CryptBlocks(ciphertext, plaintext)
fmt.Printf("%x\n", ciphertext)
}
Output: 188dc8b928ae0a13b0e9ab01127fd341
