Overview ¶

Package crypto provides an AES-GCM helper for encrypting small at-rest payloads such as RSA private keys. Callers bring their own 32-byte master key (typically loaded from a secret store).

Index ¶

Constants
Variables
func Decrypt(key, ct []byte) ([]byte, error)
func Encrypt(key, plaintext []byte) ([]byte, error)

Constants ¶

View Source

const KeySize = 32

KeySize is the required master key length in bytes (AES-256).

Variables ¶

View Source

var (
	ErrKeySize    = errors.New("crypto: master key must be 32 bytes")
	ErrCiphertext = errors.New("crypto: ciphertext too short")
)

Sentinel errors returned by Encrypt and Decrypt.

Functions ¶

func Decrypt ¶

func Decrypt(key, ct []byte) ([]byte, error)

Decrypt reverses Encrypt.

func Encrypt ¶

func Encrypt(key, plaintext []byte) ([]byte, error)

Encrypt seals plaintext with key, returning nonce||ciphertext||tag. Callers store the returned slice as-is.
