对于使用openSSL API进行公钥加密,如何在C程序中初始化密钥(公共和私有),给定* .key文件格式的私钥和* .pem文件格式的公钥:
EVP_PKEY *key;
/* How is key initialized ?
*/
ctx = EVP_PKEY_CTX_new(key);
感谢。
答案 0 :(得分:0)
试试这个:
EVP_PKEY *pkey;
FILE *f = fopen("<path for your PEM or DER encoded key>", "rb");
if (f == NULL){
// error handling...
}
//if your key is PEM encoded use this
pkey = PEM_read_PUBKEY(f, NULL, NULL, NULL); // pkey now contains the pubKey.
//We are passing NULL to the others parameters because we dont need password to read a public key
//if your key is DER encoded use this
pkey = d2i_PUBKEY_fp(f, NULL);
if (pkey == NULL){
// error handling...
}
我没有测试但应该工作。
