Types

type Cipher

type Cipher struct {
	// contains filtered or unexported fields
}

Cipher represents a cryptographic cipher using the AES (Advanced Encryption Standard) algorithm in CBC (Cipher Block Chaining) mode.

func NewES256

func NewES256(key []byte) (*Cipher, error)

NewES256 creates a new Cipher instance with the specified key for AES encryption. Parameters:

• key: The encryption key.

Returns:

• *Cipher: A pointer to the newly created Cipher instance.
• error: An error if the cipher creation fails.

func (*Cipher) Decrypt

func (c *Cipher) Decrypt(ciphertext []byte) ([]byte, error)

Decrypt decrypts the given ciphertext using the AES-CBC decryption algorithm. Parameters:

• ciphertext: The ciphertext to decrypt.

Returns:

• []byte: The decrypted plaintext.
• error: An error if decryption fails.

func (*Cipher) Encrypt

func (c *Cipher) Encrypt(plaintext []byte) ([]byte, error)

Encrypt encrypts the given plaintext using the AES-CBC encryption algorithm. Parameters:

• plaintext: The plaintext to encrypt.

Returns:

• []byte: The encrypted ciphertext.
• error: An error if encryption fails.
