Variables ¶
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.
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
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
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.
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 *sm2.PublicKey, signer crypto.Signer) ([]byte, error)
CreateCertificate 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.)

CreateRevocationList creates a new X.509 v2 Certificate Revocation List, according to RFC 5280, based on template.
The CRL is signed by priv which should be the private key associated with the public key in the issuer certificate.
The issuer may not be nil, and the crlSign bit must be set in KeyUsage in order to use it as a CRL issuer.
