Openssl 1.1.1d无效使用不完整的类型"struct dsa_st"

Openssl 1.1.1d invalid use of incomplete type ‘struct dsa_st’

本文关键字：quot struct st dsa 无效 1d 用不完 Openssl 类型      更新时间：2023-10-16

我正在从openssl 1.0.2s迁移到1.1.1d，并得到以下错误。

我在openssl文档上搜索了一下，似乎调用字段已经改变了。我不确定我需要如何在代码中实现它。

const BIGNUM * const *KeyPairImpl::getField(const string &field) const
{
if (field == "P")
return &dsa_->p;
else if (field == "Q")
return &dsa_->q;
else if (field == "G")
return &dsa_->g;
else if (field == "X")
return &dsa_->priv_key;
else if (field == "Y")
return &dsa_->pub_key;
else
// unknown field name
return NULL;
}

错误

Openssl 1.1.1不再允许直接访问内部结构。您需要使用提供的API函数来访问内部数据(如果提供(。

对于dsa_->p，请使用dsa_get0_p

对于dsa_->q，使用dsa_get0_q

对于dsa_->g，请使用dsa_get0_g

对于dsa_->priva_key，请使用dsa_get0_prival_key

对于dsa_->pub_key，请使用dsa_get0_pub_key

例如

return DSA_get0_p(dsa_);
