Hello:
I send you a function that read RSA public and
private key from a file:
RSA *RecuperaClavesRSA(int type, char
*pemfile){ FILE *fp; RSA *key=NULL; switch
(type){ case READPUB: if((fp =
fopen(pemfile,"r")) == NULL)
{ fprintf(stderr,"Error:

Can you try adding "OpenSSL_add_all_algorithms();" the line before calling "
PKCS7_dataInit".

Hi,
I'm trying to verify a signature using the following code:
BIO* cert_bio;
X509 *cert;
X509 * x509;
EVP_PKEY * pkey;
EVP_MD_CTX *md_ctx;
int sig_err;
cert_bio = BIO_new_file("vpn_test_konz.pem", "r");
if (cert_bio == NULL) {
printf("error reading PEM-file\n");
exit(1);
}
cert = PEM

It's hard to give you good suggestions without knowing more about the
specifics of your application. But I think it should be possible to make

My last Idea is you get the SSL session data from a SSL object,
do a i2d_ on it, create a new SSL_SESSION object with d2i_...,
insert that in

Yes, I have set up the call-backs exactly as in
crypto\threads\mttest.c
The problem seems to be going away when the replace
the
fseek with fclose and fopen the file again. Does this
sound weird? (considering that all threads may be
executing this code simultaneously).

Thanks Tan Eng for your answer and advice,
I tried it however the code has the same behavior ->crash in the
PKCS7_dataInit<-
I'll continue looking for.

try
pubKey=*PEM_read_RSA_PUBKEY(file, NULL,NULL,NULL);
in the place of PEM_read_RSAPublicKey.
if it doesn't work try to use the load_key function
with a PEM format in apps.c , i didn't remember where
you can find it , im not sure .
good luck.

Hi Angel,
Thank you for your response. I have changed my code with accordance to your suggestion but I'm still getting a runtime error when attempting to read the key from its file.
So far I'm having trouble with 1- reading the key from file, and 2- RSA_size() , this function generates a runtime er

Hello Layla:
Maybe, your error disapear if you will change the
following:
apub = PEM_read_RSAPublicKey(f, NULL, NULL, NULL);

Any one knows if openssl can be compiled & run in IBM
OS/390. If not, is there any other cryptographic api
that runs in IBM OS/390.

No. :( I thought I need to do that only first time I compile OpenSSL

Works fine now.
