Overview

Package pkcs12 implements some of PKCS#12.

This implementation is distilled from https://tools.ietf.org/html/rfc7292 and referenced documents. It is intended for decoding P12/PFX-stored certificates and keys for use with the crypto/tls package.

This package is frozen. If it's missing functionality you need, consider an alternative like software.sslmate.com/src/go-pkcs12.

var (
	// ErrDecryption represents a failure to decrypt the input.
	ErrDecryption = errors.New("pkcs12: decryption error, incorrect padding")

	// ErrIncorrectPassword is returned when an incorrect password is detected.
	// Usually, P12/PFX data is signed to be able to verify the password.
	ErrIncorrectPassword = errors.New("pkcs12: decryption password incorrect")
)

Functions

func Decode

func Decode(pfxData []byte, password string) (privateKey interface{}, certificate *x509.Certificate, err error)

Decode extracts a certificate and private key from pfxData. This function assumes that there is only one certificate and only one private key in the pfxData; if there are more use ToPEM instead.

func ToPEM

func ToPEM(pfxData []byte, password string) ([]*pem.Block, error)

ToPEM converts all "safe bags" contained in pfxData to PEM blocks. Unknown attributes are discarded.

Note that although the returned PEM blocks for private keys have type "PRIVATE KEY", the bytes are not encoded according to PKCS #8, but according to PKCS #1 for RSA keys and SEC 1 for ECDSA keys.

Example
p12, _ := base64.StdEncoding.DecodeString(`MIIJzgIBAzCCCZQGCS ... CA+gwggPk==`)

blocks, err := ToPEM(p12, "password")
if err != nil {
	panic(err)
}

var pemData []byte
for _, b := range blocks {
	pemData = append(pemData, pem.EncodeToMemory(b)...)
}

// then use PEM data for tls to construct tls certificate:
cert, err := tls.X509KeyPair(pemData, pemData)
if err != nil {
	panic(err)
}

config := &tls.Config{
	Certificates: []tls.Certificate{cert},
}

_ = config
Output:

Types

type NotImplementedError

type NotImplementedError string

NotImplementedError indicates that the input is not currently supported.

func (NotImplementedError) Error

func (e NotImplementedError) Error() string
