https
Hi, I have a toallylame question to anybody who can help me: I'd like to make apache work with https:// requests. I tried to create crl,crt,. keys with openssh and CA.pl, but the only thing what works with https is webalizer... :-) please help me! :-) Józsa Ádám | +36-20/984-21-96: [EMAIL PROTECTED] : http://www.kinetiks.hu :
encrypting with rsa public key..
Hi,
In my c code I am sending the rsa public key from A (which generated the
RSA key pair) to B. B now tries to encrypt a message with the public key
received from A and send the encryted message to A and A decrypts it with the
private key of the RSA key pair it generated.
Now the problem is that I cannot encrypt the message at B with the
received public key (it gives seg fault).
Is it possible to do what I have mentioned ? can you tell me where am I
going wrong ?
Here is the snippet of my code...
-
A
-
if ((rsa=RSA_generate_key(NUM_BITS,RSA_F4,NULL,NULL))==NULL) {
perror(RSA key generation failed);
}
/* Save the public and private keys into the char array */
p = ki_pub;
ki_pub_len = i2d_RSAPublicKey(rsa,p);
printf(Length of public key is %d\n,ki_pub_len);
p = ki_pri;
ki_pri_len = i2d_RSAPrivateKey(rsa,p);
printf(Length of private key is %d\n,ki_pri_len);
/* Find out the length that can be encoded by RSA */
rsa_msg_len = RSA_size(rsa);
printf(Max encoding length is %d\n,rsa_msg_len);
/* send ki_pub_len to B */
...
/* send ki_pub to B */
...
/* send rsa_msg_len to B */
...
---
B
---
/* receive ki_pub_len */
...
/* receive ki_pub */
...
/* put the ki_pub into pub_rsa */
p = ki_pub;
pub_rsa = d2i_RSAPublicKey(NULL, p, (long)ki_pub_len);
/* receive rsa_msg_len */
...
/* Encrypt message */
encrypt_len = RSA_public_encrypt(msg_len, unencrypted_mesg,
encrypted_mesg, pub_rsa,
RSA_PKCS1_OAEP_PADDING);
RSA_public_encrypt() segfaults at B.
help appreciated,
thanks,
Manish

Why the result of messages digest using md5 differs
Hi, All; Why the result of messages digest using md5 differs from using openssl md5? for example. # md5 -q -s hello 5d41402abc4b2a76b9719d911017c592 but when I used openssl. #echo hello | openssl md5 f447b20a7fcbf53a5d5be013ea0b15af why are they different? I used openssl 0.9.6d on FreeBsd4.2 UNIX. thans your help __ Do You Yahoo!? Yahoo!

Re: RSA public and private key lengths (newbie question)
Hi, Thanks a lot for the reply. I have one more question. The private key contains all the RSA key data whereas the public key contains just the public components. So yes, this is normal. Cheers, Geoff Since public key contains only the public components is it possible to encrypt a message using RSA_public_encrypt() with a RSA struct having just the public key i.e. RSA struct obtained from rsa = d2i_RSAPublicKey(..)
