Okay. Thanks Matt, I didn’t see that one in x509_vfy.c, I must look harder. I will modify our own copy of OpenSSL1.1.1c to provide the missing functions and open a PR on the master.

Hello Everyone. I am migrating code written to the old 1.0 (actually probably more like 0.9.?) X509_STORE API which has a replacement for the check_issuer callback function. Unless I am missing something the 1.1.1c SDK’s public API is missing some accessor functions that are required for a like-for-like update to 1.1.1c. void X509_STORE_CTX_set0_current_issuer(X509_STORE_CTX *ctx, X509 *cert){ ctx->current_issuer = cert; } void X509_STORE_CTX_set0_error(X509_STORE_CTX *ctx, int error) { ctx->error = error; } I suspect I will need to build this as an internal OpenSSL source module in order to allow access inside the STORE structure. Or, have I missed a replacement API somewhere? The reason for using our own callback function is to allow for the situation where a trustpoint collection may contain multiple certificates with the same DN but different keys. The second (or later) of these may be the signer of the certificate
being verified. The OpenSSL version would stop when it encountered the first certificate with an incorrect key. If OpenSSL now supports this situation we could remove the need to set our own callback. Simon Edwards Micro Focus The Lawn, 22-30 Old Bath Road Shoretel 44224 |
