我有一个Java文件,当我编译时,在java编译器(javac)退出之后,我将只能在控制台上看到前100个错误.我怎样才能在控制台上看到所有编译错误？在此先感谢 - opensid
我有DER和PEM格式的证书,我的目标是检索Issuer和Subject的字段,并使用CA公钥验证证书,同时使用根公钥验证CA证书.我能够检索发行人和主题的所有细节,但无法验证证书.
使用的API:
x509 = d2i_X509_fp (fp, &x509); //READING DER Format
x509 = PEM_read_X509 (fp, &x509, NULL, NULL); //READING PEM Format
//to retrieve the Subject:
X509_NAME_oneline(X509_get_subject_name(x509), subject, sizeof (subject));
//to retrieve the Issuer:
X509_NAME_oneline(X509_get_issuer_name(x509), issuer, sizeof (issuer));
//To store the CA public key (in unsigned char *key) that will be used to verify the
//certificate (in my case always sha1WithRSAEncryption):
RSA *x = X509_get_pubkey(x509)->pkey.rsa;
bn = x->n;
//extracts the bytes from public key & convert into unsigned char buffer
buf_len = …Certificate:

X509v3 Authority Key …我有一个DER证书,我从中检索unsigned char缓冲区中的公钥,如下所示,这是正确的获取方式吗？
pStoredPublicKey = X509_get_pubkey(x509);
if(pStoredPublicKey == NULL)
{
printf(": publicKey is NULL\n");
}
if(pStoredPublicKey->type == EVP_PKEY_RSA) {
RSA *x = pStoredPublicKey->pkey.rsa;
bn = x->n;
}
else if(pStoredPublicKey->type == EVP_PKEY_DSA) {
}
else if(pStoredPublicKey->type == EVP_PKEY_EC) {

else {
printf(" : Unkown publicKey\n");
}
//extracts the bytes from public key & convert into unsigned char buffer
buf_len = (size_t) BN_num_bytes (bn);
key = (unsigned char *)malloc (buf_len);
n = BN_bn2bin (bn, (unsigned char *) key);
