Struct CmsContentInfo 

pub struct CmsContentInfo(/* private fields */);

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 implementation.

Implementations

impl CmsContentInfo

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

Parses a smime formatted vec of bytes into a CmsContentInfo.

This corresponds to 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.

This corresponds to CMS_sign.

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.

OpenSSL documentation at CMS_encrypt

This corresponds to CMS_encrypt.

pub fn verify( &mut self, certs: Option<&StackRef<X509>>, store: Option<&X509StoreRef>, detached_data: Option<&[u8]>, output_data: Option<&mut Vec<u8>>, flags: CMSOptions, ) -> Result<(), ErrorStack>

Verify this CmsContentInfo’s signature, This will search the ‘certs’ list for the signing certificate.
Additional certificates, needed for building the certificate chain, may be given in ‘store’ as well as additional CRLs. A detached signature may be passed in detached_data. The signed content without signature, will be copied into output_data if it is present.

This corresponds to CMS_verify.

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 certificate, cert, decrypt the data in self.

This corresponds to CMS_decrypt.

pub fn decrypt_without_cert_check<T>( &self, pkey: &PKeyRef<T>, ) -> Result<Vec<u8>, ErrorStack>

where T: HasPrivate,

Given the sender’s private key, pkey, decrypt the data in self without validating the recipient certificate.

Warning: Not checking the recipient certificate may leave you vulnerable to Bleichenbacher’s attack on PKCS#1 v1.5 RSA padding.

This corresponds to CMS_decrypt.

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

Serializes this CmsContentInfo using DER.

This corresponds to i2d_CMS_ContentInfo.

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

Serializes this CmsContentInfo using DER.

This corresponds to PEM_write_bio_CMS.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
