Variables

View Source 
var ContentEncryptionAlgorithm = EncryptionAlgorithmDESCBC

ContentEncryptionAlgorithm determines the algorithm used to encrypt the plaintext message. Change the value of this variable to change which algorithm is used in the Encrypt() function.

View Source 
var ErrNotEncryptedContent = errors.New("pkcs7: content data is a decryptable data type")

ErrNotEncryptedContent is returned when attempting to Decrypt data that is not encrypted data

View Source 
var ErrPKCS7UnsupportedAlgorithm = errors.New("pkcs7: cannot decrypt data: only RSA, DES, DES-EDE3, AES-256-CBC and AES-128-GCM supported")

ErrPKCS7UnsupportedAlgorithm tells you when our quick dev assumptions have failed

View Source 
var ErrUnsupportedAlgorithm = errors.New("x509: cannot verify signature: algorithm unimplemented")

ErrUnsupportedAlgorithm results from attempting to perform an operation that involves algorithms that are not currently implemented.

View Source 
var ErrUnsupportedContentType = errors.New("pkcs7: cannot parse data: unimplemented content type")

ErrUnsupportedContentType is returned when a PKCS7 content is not supported. Currently only Data (1.2.156.10197.6.1.4.2.1), Signed Data (1.2.156.10197.6.1.4.2.2), and Enveloped Data are supported (1.2.156.10197.6.1.4.2.3)

Functions

func CreateCertificate 

func CreateCertificate(template, parent *Certificate, publicKey crypto.PublicKey, signer crypto.Signer) ([]byte, error)

CreateSM2Certificate creates a new certificate based on a template. The following members of template are used: SerialNumber, Subject, NotBefore, NotAfter, KeyUsage, ExtKeyUsage, UnknownExtKeyUsage, BasicConstraintsValid, IsCA, MaxPathLen, SubjectKeyId, DNSNames, PermittedDNSDomainsCritical, PermittedDNSDomains, SignatureAlgorithm.

The certificate is signed by parent. If parent is equal to template then the certificate is self-signed. The parameter pub is the public key of the signee and priv is the private key of the signer.

The returned slice is the certificate in DER encoding.

All keys types that are implemented via crypto.Signer are supported (This includes *rsa.PublicKey and *ecdsa.PublicKey.)

func CreateCertificateRequest 

func CreateCertificateRequest(rand io.Reader, template *CertificateRequest, signer crypto.Signer) (csr []byte, err error)

CreateCertificateRequest creates a new certificate request based on a template. The following members of template are used: Subject, Attributes, SignatureAlgorithm, Extensions, DNSNames, EmailAddresses, and IPAddresses. The private key is the private key of the signer.

The returned slice is the certificate request in DER encoding.

All keys types that are implemented via crypto.Signer are supported (This includes *rsa.PublicKey and *ecdsa.PublicKey.)

	CurrentTime   time.Time // if zero, the current time is used
	// KeyUsage specifies which Extended Key Usage values are acceptable.
	// An empty list means ExtKeyUsageServerAuth. Key usage is considered a
	// constraint down the chain which mirrors Windows CryptoAPI behavior,
	// but not the spec. To accept any key usage, include ExtKeyUsageAny.
	KeyUsages []ExtKeyUsage
}

VerifyOptions contains parameters for Certificate.Verify. It's a structure because other PKIX verification APIs have ended up needing many options.
