This implementation is limited to - * DER only. - * - The RFC specifies that multiple digest algorithms can be specified - * in the Signed Data type. Only one digest algorithm is supported in Mbed TLS. - * - The RFC specifies the Signed Data type can contain multiple X.509 or PKCS #6 extended - * certificates. In Mbed TLS, this list can only contain 0 or 1 certificates - * and they must be in X.509 format. - * - The RFC specifies the Signed Data type can contain - * certificate-revocation lists (CRLs). This implementation has no support - * for CRLs so it is assumed to be an empty list. - * - The RFC allows for SignerInfo structure to optionally contain - * unauthenticatedAttributes and authenticatedAttributes. In Mbed TLS it is - * assumed these fields are empty. - * - The RFC allows for the signed Data type to contain contentInfo. This - * implementation assumes the type is DATA and the content is empty. - */ - -#ifndef MBEDTLS_PKCS7_H -#define MBEDTLS_PKCS7_H - -#include "mbedtls/private_access.h" - -#include "mbedtls/build_info.h" - -#include "mbedtls/asn1.h" -#include "mbedtls/x509.h" -#include "mbedtls/x509_crt.h" - -/** - * \name PKCS #7 Module Error codes - * \{ - */ -#define MBEDTLS_ERR_PKCS7_INVALID_FORMAT -0x5300 /**< The format is invalid, e.g. different type expected. */ -#define MBEDTLS_ERR_PKCS7_FEATURE_UNAVAILABLE -0x5380 /**< Unavailable feature, e.g. anything other than signed data. */ -#define MBEDTLS_ERR_PKCS7_INVALID_VERSION -0x5400 /**< The PKCS #7 version element is invalid or cannot be parsed. */ -#define MBEDTLS_ERR_PKCS7_INVALID_CONTENT_INFO -0x5480 /**< The PKCS #7 content info is invalid or cannot be parsed. */ -#define MBEDTLS_ERR_PKCS7_INVALID_ALG -0x5500 /**< The algorithm tag or value is invalid or cannot be parsed. */ -#define MBEDTLS_ERR_PKCS7_INVALID_CERT -0x5580 /**< The certificate tag or value is invalid or cannot be parsed. */ -#define MBEDTLS_ERR_PKCS7_INVALID_SIGNATURE -0x5600 /**< Error parsing the signature */ -#define MBEDTLS_ERR_PKCS7_INVALID_SIGNER_INFO -0x5680 /**< Error parsing the signer's info */ -#define MBEDTLS_ERR_PKCS7_BAD_INPUT_DATA -0x5700 /**< Input invalid. */ -#define MBEDTLS_ERR_PKCS7_ALLOC_FAILED -0x5780 /**< Allocation of memory failed. */ -#define MBEDTLS_ERR_PKCS7_VERIFY_FAIL -0x5800 /**< Verification Failed */ -#define MBEDTLS_ERR_PKCS7_CERT_DATE_INVALID -0x5880 /**< The PKCS #7 date issued/expired dates are invalid */ -/* \} name */ - -/** - * \name PKCS #7 Supported Version - * \{ - */ -#define MBEDTLS_PKCS7_SUPPORTED_VERSION 0x01 -/* \} name */ - -#ifdef __cplusplus -extern "C" { -#endif - -/** - * Type-length-value structure that allows for ASN.1 using DER. - */ -typedef mbedtls_asn1_buf mbedtls_pkcs7_buf; - -/** - * Container for ASN.1 named information objects. - * It allows for Relative Distinguished Names (e.g. cn=localhost,ou=code,etc.). - */ -typedef mbedtls_asn1_named_data mbedtls_pkcs7_name; - -/** - * Container for a sequence of ASN.1 items - */ -typedef mbedtls_asn1_sequence mbedtls_pkcs7_sequence; - -/** - * PKCS #7 types - */ -typedef enum { - MBEDTLS_PKCS7_NONE=0, - MBEDTLS_PKCS7_DATA, - MBEDTLS_PKCS7_SIGNED_DATA, - MBEDTLS_PKCS7_ENVELOPED_DATA, - MBEDTLS_PKCS7_SIGNED_AND_ENVELOPED_DATA, - MBEDTLS_PKCS7_DIGESTED_DATA, - MBEDTLS_PKCS7_ENCRYPTED_DATA, -} -mbedtls_pkcs7_type; - -/** - * Structure holding PKCS #7 signer info - */ -typedef struct mbedtls_pkcs7_signer_info { - int MBEDTLS_PRIVATE(version); - mbedtls_x509_buf MBEDTLS_PRIVATE(serial); - mbedtls_x509_name MBEDTLS_PRIVATE(issuer); - mbedtls_x509_buf MBEDTLS_PRIVATE(issuer_raw); - mbedtls_x509_buf MBEDTLS_PRIVATE(alg_identifier); - mbedtls_x509_buf MBEDTLS_PRIVATE(sig_alg_identifier); - mbedtls_x509_buf MBEDTLS_PRIVATE(sig); - struct mbedtls_pkcs7_signer_info *MBEDTLS_PRIVATE(next); -} -mbedtls_pkcs7_signer_info; - -/** - * Structure holding the signed data section - */ -typedef struct mbedtls_pkcs7_signed_data { - int MBEDTLS_PRIVATE(version); - mbedtls_pkcs7_buf MBEDTLS_PRIVATE(digest_alg_identifiers); - int MBEDTLS_PRIVATE(no_of_certs); - mbedtls_x509_crt MBEDTLS_PRIVATE(certs); - int MBEDTLS_PRIVATE(no_of_crls); - mbedtls_x509_crl MBEDTLS_PRIVATE(crl); - int MBEDTLS_PRIVATE(no_of_signers); - mbedtls_pkcs7_signer_info MBEDTLS_PRIVATE(signers); -} -mbedtls_pkcs7_signed_data; - -/** - * Structure holding PKCS #7 structure, only signed data for now - */ -typedef struct mbedtls_pkcs7 { - mbedtls_pkcs7_buf MBEDTLS_PRIVATE(raw); - mbedtls_pkcs7_signed_data MBEDTLS_PRIVATE(signed_data); -} -mbedtls_pkcs7; - -/** - * \brief Initialize mbedtls_pkcs7 structure. - * - * \param pkcs7 mbedtls_pkcs7 structure. - */ -void mbedtls_pkcs7_init(mbedtls_pkcs7 *pkcs7); - -/** - * \brief Parse a single DER formatted PKCS #7 detached signature. - * - * \param pkcs7 The mbedtls_pkcs7 structure to be filled by the parser. - * \param buf The buffer holding only the DER encoded PKCS #7 content. - * \param buflen The size in bytes of \p buf.
