Overview ¶

Package crypto provides authenticated symmetric encryption (AES-256-GCM) for secrets stored at rest, such as registry credentials. The key is generated once and persisted alongside the other server secrets.

Types ¶

type Cipher ¶

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

Cipher seals and opens short secrets with AES-GCM. The nonce is random per message and prepended to the ciphertext; output is base64 for DB storage.

func New ¶

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

New returns a Cipher for a 16/24/32-byte key (32 = AES-256).

func (*Cipher) Decrypt ¶

func (c *Cipher) Decrypt(enc string) (string, error)

Decrypt reverses Encrypt. A wrong key or tampered ciphertext yields an error.

func (*Cipher) Encrypt ¶

func (c *Cipher) Encrypt(plain string) (string, error)

Encrypt seals plaintext and returns base64(nonce || ciphertext).
