Types ¶
type AES128 ¶
type AES128 struct {
// contains filtered or unexported fields
}
AES128 provides AES encryption with a 128-bit key.
Example ¶
package main
import (
"fmt"
"github.com/exonlabs/go-utils/pkg/ciphering"
)
func main() {
// Create a new AES-128 handler with a secret key
aes128, err := ciphering.NewAES128("mysecret")
if err != nil {
fmt.Println(err)
}
// Data to be encrypted
plaintext := []byte("This is a secret message")
// Encrypt the data
ciphertext, err := aes128.Encrypt(plaintext)
if err != nil {
fmt.Println(err)
}
// Decrypt the data
decrypted, err := aes128.Decrypt(ciphertext)
if err != nil {
fmt.Println(err)
}
fmt.Printf("Decrypted: %s\n", decrypted)
}
Output: Decrypted: This is a secret message
func NewAES128 ¶
NewAES128 creates a new AES-128 handler using the provided secret. The secret is hashed with SHA-256 to derive a 128-bit key and AAD.
type AES256 ¶
type AES256 struct {
// contains filtered or unexported fields
}
AES256 provides AES encryption with a 256-bit key.
Example ¶
package main
import (
"fmt"
"github.com/exonlabs/go-utils/pkg/ciphering"
)
func main() {
// Create a new AES-256 handler with a secret key
aes256, err := ciphering.NewAES256("anothersecret")
if err != nil {
fmt.Println(err)
}
// Data to be encrypted
plaintext := []byte("Another secret message")
// Encrypt the data
ciphertext, err := aes256.Encrypt(plaintext)
if err != nil {
fmt.Println(err)
}
// Decrypt the data
decrypted, err := aes256.Decrypt(ciphertext)
if err != nil {
fmt.Println(err)
}
fmt.Printf("Decrypted: %s\n", decrypted)
}
Output: Decrypted: Another secret message
func NewAES256 ¶
NewAES256 creates a new AES-256 handler using the provided secret. The secret is hashed with SHA-512 to derive a 256-bit key and AAD.
