You should not have to distinguish. The key type
Thank you viktor,
Actually, I'm begginer so I don't know well.
You said that the my input data is not a PKCS # 1 public key type.
How do I distinguish between a PKCS # 1 type or an X.509 SPKI Public Key?

Your input data is not a PKCS#1 RSA public key a
I am getting RSA publickey from the server.
I need to extract the modulus and public exponent from the key to do the RSA
operation.
I have to solve with C language code, not shell command.
I have written the following test code, and an error has occurred in the
d2i_RSAPublicKey function.

Marvelous. That's solved my problem.
Thank you for your time and input Dr. Henson.

Yes, the formats are incompatible. You need d2i_RSA_PUBKEY() instead.

But i think you have to free the memory using OPENSSSL_free().

So I need to save buf to a tmp first like with d2i_RSAPublicKey?
Like this:
int len = i2d_RSAPublicKey(rsa, 0);
unsigned char* buf = new unsigned char[len];
unsigned char* tmp = buf;
i2d_RSAPublicKey(rsa, &tmp);
// now use buf to decode
Is this correct?

No, this code is wrong for the reasons mention
cate buffer
unsigned char* buf = new unsigned char[len];
// now call again to DER encode the public key
if (i2d_RSAPublicKey(rsa, &buf) == len)
{
// now try to decode the buffer
unsigned char* tmp = buf;
RSA* public_key = d2i

That part of the code remains the same, and continues to work fine. By
the way, my last code snippet should have been:
U8* tmp = buf;
RSA* pub = d2i_RSAPublicKey(0, (const U8**)&tmp, len);
I mistakenly typed *len instead of len.
Anyways, after I call i2d_RSAPublicKey, calling d2i_RSAPubli
to the same address.

I see where it says you need to create the temp var. So changed my code
to do that, but I still get a null ptr returned.
Code is now:
U8* tmp = buf;
RSA* pub = d2i_RSAPublicKey(0, (const U8**)&tmp,
to the same address.

buf gets

the following, and it fails.
RSA* public_key = d2i_RSAPublicKey(0, (const U8**)&buf,
len); // public_key is NULL; why???
Title: d2i_RSAPublicKey doesn't work
What am I doing wrong here? I generate an RSA key. Then I DER encode it. Then try to decode it, but the decode fails. The error says, "error:0D07207B:asn1 encoding routines:ASN1_get_object:header too long"
RSA* rsa = RSA_generate_key(

printCadena(KCtx->keystr,KCtx->derlen);
rsa=d2i_RSAPublicKey(NULL,&ptr,KCtx->derlen);
But I obtain a NULL (rsa == NULL)

length is the length of the *pp data, that means it is the number of bytes that you
want to convert from DER to internal form, starting
Hello.
RSA * d2i_RSAPublicKey(RSA **a, unsigned char **pp, long length);
What does length param mean?
Thank you.
