Types ¶

type Bits ¶

type Bits = int

Bits denotes the number of bits used for key creation / generation

type RSA ¶

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

RSA denotes an RSA public / private key pair

func New ¶

func New(bits Bits) (obj *RSA, err error)

New creates a new elliptic curve key pair

func NewFromPEM ¶

func NewFromPEM(privPEM *pem.Block) (obj *RSA, err error)

NewFromPEM reads a private key from a PEM block

func NewFromString ¶

func NewFromString(str string) (obj *RSA, err error)

NewFromString reads a private key / RSA object from a base64 encoded string

func (*RSA) Decrypt ¶

func (e *RSA) Decrypt(cipherMsg []byte, h hash.Hash) ([]byte, error)

Decrypt decrypts a message using RSA-OAEP, using the hash h (falling back to sha256 if nil)

func (*RSA) Encrypt ¶

func (e *RSA) Encrypt(clearMsg []byte, h hash.Hash) ([]byte, error)

Encrypt encrypts a message using RSA-OAEP, using the hash h (falling back to sha256 if nil)

func (*RSA) PrivKey ¶

func (e *RSA) PrivKey() *rsa.PrivateKey

PrivKey returns the private key

func (*RSA) PrivKeyPEM ¶

func (e *RSA) PrivKeyPEM() *pem.Block

PrivKeyPEM returns the private key as PEM block

func (*RSA) PrivKeyString ¶

func (e *RSA) PrivKeyString() string

PrivKeyString returns the private key as base64 encoded PEM block

func (*RSA) PubKey ¶

func (e *RSA) PubKey() *rsa.PublicKey

PubKey returns the public key

func (*RSA) PubKeyPEM ¶

func (e *RSA) PubKeyPEM() *pem.Block

PubKeyPEM returns the public key as PEM block
