Function sgx_tcrypto::rsgx_rsa3072_verify_msg

pub fn rsgx_rsa3072_verify_msg<T>(
    data: &T, 
    public: &sgx_rsa3072_public_key_t, 
    signature: &sgx_rsa3072_signature_t
) -> SgxResult<bool> where
    T: Copy + ContiguousMemory, 

rsgx_rsa3072_verify_msg verifies the input digital signature for the given data- set based on the RSA 3072 public key.

Description

This function verifies the signature for the given data set based on the input RSA 3072 public key.

A digital signature over a message is a buffer of 384-bytes, which could be created by function: rsgx_rsa3072_sign. The scheme used for computing a digital signature is of the RSASSA-PKCS1-v1_5 scheme.

Parameters

data

A pointer to the signed dataset to be verified.

public

A pointer to the public key to be used in the calculation of the signature.

signature

A pointer to the signature to be verified.

Requirements

Library: libsgx_tcrypto.a

Return value

true

Digital signature is valid.

false

Digital signature is not valid.

Errors

SGX_ERROR_INVALID_PARAMETER

The private key, data is NULL. Or the data size is 0.

SGX_ERROR_OUT_OF_MEMORY

Not enough memory is available to complete this operation.

SGX_ERROR_UNEXPECTED

The verification process failed due to an internal cryptography library failure.
