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, which must be a DER-encoded PKCS#12 file. This function assumes that there is only one certificate and only one private key in the pfxData. Since PKCS#12 files often contain more than one certificate, you probably want to use DecodeChain instead.

func DecodeChain

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

DecodeChain extracts a certificate, a CA certificate chain, and private key from pfxData, which must be a DER-encoded PKCS#12 file. This function assumes that there is at least one certificate and only one private key in the pfxData. The first certificate is assumed to be the leaf certificate, and subsequent certificates, if any, are assumed to comprise the CA certificate chain.

func Encode

func Encode(rand io.Reader, privateKey interface{}, certificate *x509.Certificate, caCerts []*x509.Certificate, password string) (pfxData []byte, err error)

Encode produces pfxData containing one private key (privateKey), an end-entity certificate (certificate), and any number of CA certificates (caCerts).

The private key is encrypted with the provided password, but due to the weak encryption primitives used by PKCS#12, it is RECOMMENDED that you specify a hard-coded password (such as [DefaultPassword]) and protect the resulting pfxData using other means.

The rand argument is used to provide entropy for the encryption, and can be set to crypto/rand.Reader.

Encode emulates the behavior of OpenSSL's PKCS12_create: it creates two SafeContents: one that's encrypted with RC2 and contains the certificates, and another that is unencrypted and contains the private key shrouded with 3DES The private key bag and the end-entity certificate bag have the LocalKeyId attribute set to the SHA-1 fingerprint of the end-entity certificate.

Types

type NotImplementedError string

NotImplementedError indicates that the input is not currently supported.
