Variables

var ErrTooShort = errors.New("SealedSecret data is too short")

ErrTooShort indicates the provided data is too short to be valid.

Functions

func GeneratePrivateKeyAndCert

func GeneratePrivateKeyAndCert(keySize int, validFor time.Duration, cn string) (*rsa.PrivateKey, *x509.Certificate, error)

GeneratePrivateKeyAndCert generates a keypair and signed certificate.

func HybridDecrypt

func HybridDecrypt(rnd io.Reader, privKeys map[string]*rsa.PrivateKey, ciphertext, label []byte) ([]byte, error)

HybridDecrypt performs a regular AES-GCM + RSA-OAEP decryption. The private keys map has a fingerprint of each public key as the map key.

func HybridEncrypt

func HybridEncrypt(rnd io.Reader, pubKey *rsa.PublicKey, plaintext, label []byte) ([]byte, error)

HybridEncrypt performs a regular AES-GCM + RSA-OAEP encryption. The output byte string is:

RSA ciphertext length || RSA ciphertext || AES ciphertext

func PublicKeyFingerprint

func PublicKeyFingerprint(rp *rsa.PublicKey) (string, error)

PublicKeyFingerprint returns a fingerprint for a public key.

func SignKey

func SignKey(r io.Reader, key *rsa.PrivateKey, validFor time.Duration, cn string) (*x509.Certificate, error)

SignKey returns a signed certificate.

func SignKeyWithNotBefore

func SignKeyWithNotBefore(r io.Reader, key *rsa.PrivateKey, notBefore time.Time, validFor time.Duration, cn string) (*x509.Certificate, error)

SignKeyWithNotBefore returns a signed certificate with custom notBefore.
