mbedtls_pkcs7_parse_der() function
Parse a single DER formatted PKCS #7 detached signature.
Syntax
Implemented in ![]()
pkcs7.c:553
Return value
The \c mbedtls_pkcs7_type of \p buf, if successful. A negative error code on failure.
Notes
This function makes an internal copy of the PKCS #7 buffer \p buf. In particular, \p buf may be destroyed or reused after this call returns. Signatures with internal data are not supported.

Function
Description
Unallocate all PKCS #7 data and zeroize the memory. It doesn't free \p pkcs7 itself. This should be done by the caller.
Initialize mbedtls_pkcs7 structure.
Verification of PKCS #7 signature against a caller-supplied certificate. For each signer in the PKCS structure, this function computes a signature over the supplied data, using the supplied certificate and the same digest algorithm as specified by the signer. It then compares this signature against the signer's signature; verification succeeds if any comparison matches. This function does not use the certificates held within the PKCS #7 structure itself, and does not check that the certificate is signed by a trusted certification authority.
Verification of PKCS #7 signature against a caller-supplied certificate. For each signer in the PKCS structure, this function validates a signature over the supplied hash, using the supplied certificate and the same digest algorithm as specified by the signer. Verification succeeds if any signature is good. This function does not use the certificates held within the PKCS #7 structure itself, and does not check that the certificate is signed by a trusted certification authority.
