Extracting certificate serial numbers from a CRL

Dear list, I am receiving a CRL. After checking its validity against the issuer's certificate, I would like to use the API to access the certificate serial numbers of the revoked certificates. With the command line and asn1parse I can check the serial numbers and the dates of revocation as INTEGE

d2i/i2d_EC_PUBKEY_bio and d2i/i2d_EC_PUBKEY_fp functions

Dear list,I used the "ecdhtest.c" file as starting point to write a small test application to do ECDH key exchange over a network. In order to encode the peer's public keys in a TCP message I used the i2d_EC_PUBKEY_bio functions to write the public keys to memory BIOs, and from the BIOs to the TCP

Hi Nils,the problem was between the keyboard and the chair :-)I picked the worst moment to mix up Alice and Bob... the OpenSSL d2i/i2d functions provided have no problems at all.Cheers,Jordi 2006/11/3, Nils Larsch <[EMAIL PROTECTED]>: Jordi Jaen Pallares wrote:> Dear list,>> I used

How to read a EC_KEY from a certificate

Dear list, I am writing an application that uses ECC and certificates. At initialization time, the idea is to generate both a self-signed root certificate (as in the examples in the /demos examples) for the CA, and a set of long terms EC keys for each client. In the program I intend to use both
