Connect using IP address instead of URL "509 - Certificate verification failed, e.g. CRL, CA or signature check failed"

by M M

I am using MbedTLS client code based on this: https://github.com/machinezone/IXWebSocket/blob/master/ixwebsocket/IXSocket… I am connecting to a server via it's URL. However, I would like to connect directly using an IP address returned from running the traceroute command on the URL. So I replaced the URL with the IP address. However, MBedTLS fails on the handshake: https://github.com/machinezone/IXWebSocket/blob/master/ixwebsocket/IXSocket… I get the error: "error in handshake : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed" If I revert back to URL, it works. The IP address does exist. How can I connect using the IP address, instead of the URL?

Error while parsing certificate

by Subramanian Gopi Krishnan

Hi, I have an inhouse developed secure authentication program that uses certificate for authentication. I have used mbedtls library for the x.509 certificate verification purpose. In our custom PKI we have only three level of certificates, Root-CA -> Intermediate-CA -> Device-Cert. The embedded device has very limited memory, so instead of sending whole certificate chain, the devices communicates intermediate_CA and device cert (in der format base64 encoded) in separate packet. Root-CA will be available on node as trusted-ca. Intermediate is verified against Root; then device cert is verified against intermediate. The problem is, the poc developed on linux platform is working fine - but on embedded platform I encounter either 0x3b00(parsing failed) or 0x2700(with flag 8). Also the error code are inconsistent. I verified the integrity of packet with certificate using crc16. So no chance of certificate getting corrupted. Also verified the certificate's base64 format integrity using crc16. All certificates are sha256WithRSAEncryption; RSA Public-Key: (4096 bit) Attached config.h on target platform for reference - could you help me if anything wrong with configuration. While trying to trace, the flag was set from x509_crt.c from below code. /* No parent? We're done here */ if( parent == NULL ) { printf("NO_PARENT\r\n"); *flags |= MBEDTLS_X509_BADCERT_NOT_TRUSTED; return( 0 ); } Any clue would be helpful. Thanks, Gopi Krishnan
