Function sgx_ucrypto::rsgx_rsa3072_sign_msg

pub fn rsgx_rsa3072_sign_msg<T>(
    data: &T, 
    key: &sgx_rsa3072_key_t
) -> SgxResult<sgx_rsa3072_signature_t> where
    T: Copy + ContiguousMemory, 

The rsgx_rsa3072_sign_msg computes a digital signature for a given dataset based on RSA 3072 private key.

Description

This function computes a digital signature over the input dataset based on the RSA 3072 private key.

A message digest is a fixed size number derived from the original message with an applied hash function over the binary code of the message. (SHA256 in this case)

The signer's private key and the message digest are used to create a signature.

The scheme used for computing a digital signature is of the RSASSA-PKCS1-v1_5 scheme.

Parameters

data

A pointer to the data to calculate the signature over.

key

A pointer to the RSA key.

Requirements

Library: libsgx_tcrypto.a

Return value

The signature generated by this function.

Errors

SGX_ERROR_INVALID_PARAMETER

The RSA 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 signature generation process failed due to an internal cryptography library failure.
