## Detailed Description

Parameter structure for function mcuxClEcc_Sign.

## Field Documentation

## ◆ curveParam

mcuxClEcc_DomainParam_t mcuxClEcc_Sign_Param_t::curveParam

[in] structure of pointers to curve parameters and length of parameters.

## ◆ pHash

const uint8_t* mcuxClEcc_Sign_Param_t::pHash

[in] pointer to string of message digest (hash), of which the length is byteLenHash (in optLen).

## ◆ pPrivateKey

const uint8_t* mcuxClEcc_Sign_Param_t::pPrivateKey

[in] pointer to octet string of private key, which is of the same format as base point order n.

## ◆ pSignature

uint8_t* mcuxClEcc_Sign_Param_t::pSignature

[out] pointer to memory area in which signature R and S will be exported if signature is generated successfully.

They will be stored as Big-endian octet strings of the exact length curveParam.byteLenN. The string of R is followed by the string of S.

## ◆ optLen

uint32_t mcuxClEcc_Sign_Param_t::optLen

[in] packed options (reserved) and lengths: bits 0~7: byteLenHash: length of the string of message digest; bits 8~31: reserved.
