Struct openssl::cms::CmsContentInfo

pub struct CmsContentInfo(_);

High level CMS wrapper

CMS supports nesting various types of data, including signatures, certificates, encrypted data, smime messages (encrypted email), and data digest. The ContentInfo content type is the encapsulation of all those content types. RFC 5652 describes CMS and OpenSSL follows this RFC's implmentation.

Implementations

impl CmsContentInfo

pub fn smime_read_cms(smime: &[u8]) -> Result<CmsContentInfo, ErrorStack>

Parses a smime formatted vec of bytes into a CmsContentInfo.

OpenSSL documentation at SMIME_read_CMS

pub fn from_der(der: &[u8]) -> Result<CmsContentInfo, ErrorStack>

Deserializes a DER-encoded ContentInfo structure.

This corresponds to d2i_CMS_ContentInfo.

pub fn from_pem(pem: &[u8]) -> Result<CmsContentInfo, ErrorStack>

Deserializes a PEM-encoded ContentInfo structure.

This corresponds to PEM_read_bio_CMS.

pub fn sign<T>(
    signcert: Option<&X509Ref>,
    pkey: Option<&PKeyRef<T>>,
    certs: Option<&StackRef<X509>>,
    data: Option<&[u8]>,
    flags: CMSOptions
) -> Result<CmsContentInfo, ErrorStack> where
    T: HasPrivate, 

Given a signing cert signcert, private key pkey, a certificate stack certs, data data and flags flags, create a CmsContentInfo struct.

All arguments are optional.

pub fn encrypt(
    certs: &StackRef<X509>,
    data: &[u8],
    cipher: Cipher,
    flags: CMSOptions
) -> Result<CmsContentInfo, ErrorStack>

Given a certificate stack certs, data data, cipher cipher and flags flags, create a CmsContentInfo struct.

Methods from Deref<Target = CmsContentInfoRef>

pub fn decrypt<T>(
    &self,
    pkey: &PKeyRef<T>,
    cert: &X509
) -> Result<Vec<u8>, ErrorStack> where
    T: HasPrivate, 

Given the sender's private key, pkey and the recipient's certificiate, cert, decrypt the data in self.

OpenSSL documentation at CMS_decrypt

pub fn to_der(&self) -> Result<Vec<u8>, ErrorStack>

Serializes this CmsContentInfo using DER.

OpenSSL documentation at i2d_CMS_ContentInfo

pub fn to_pem(&self) -> Result<Vec<u8>, ErrorStack>

Serializes this CmsContentInfo using DER.
