Thanks again Richard for your help. I found out that I was using
std::string::append in my code, and that append stopped reading when it
reached a NULL byte in the signature(which is a valid byte given the hash
function) and that was truncating the signature.

Thanks so much for your response Richard. I appreciate your time. That's
pretty much the same thing I'm doing

Well That's interesting. when I download and use your .sig file, I get the
same errors. How do you go about picking up your signature form the file
system?

Hello,
I am trying to verify a signature using
EVP_digestVerifyInit/Update/Final, and I keep getting the errors
ASN1_get_object:too long or ASN1_CHEKC_TLEN: Bad Object Header or Wrong
Tag, and finally ASN1_ITEM_EX_D2I: Nested asn1 error. I believe that these
errors indicate that the formatting

To see the format used you can do:
openssl rsautl -verify -certin -in signature -inkey cert.pem -hexdump
and post the result. Also try it with the -asn1parse option instead of
-hexdump.
# openssl rsautl -verify -certin -in signature -inkey vpn_test_konz.pem
-asn1parse
Error in encoding

if (err != 1) {

Abdou,
That's almost exactly how I got the errors
I did:
sig_err = EVP_VerifyFinal(md_ctx, signature, signature_length, pkey);
printf("Signature-Verification: %d\n",
make this test to see exactly what you have as
errors.
if (err != 1) {
ERR_print_errors_fp (stderr);
exit (1);
}
Abdou,

The "signature" contains the value which is extracted from the
socket-datastream and is 128Bytes (1024bit) long.
What is in a signature in DER format? - Is it just the signature itself
or is there additional information?
What do the error-messages mean -
- Is there some problem while verifying (
I think that the format of the signature make problem,
normally the standard format of signature is a DER
format.

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
