Hi, Our application can have several certificates to use when acting as an SSL client. In order to choose the right certificate for each connection we intend to set a callback using SSL_CTX_set_client_cert_cb that will return the private key and certificate to use. In this callback we need to access the certificate_authorities field of the CertificateRequest message. How can we get hold of that information? -- Roger ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
