问题
I have an established SSL connection. My context is loaded with trustchain.pem file which contains all the CA info.
During runtime, I am adding a new CA.pem
When this addition is made the existing rustchain.pem is reloaded and the new file is taken into its list.
Now if I add the new trustchain.pem file into the SSL_CTX using SSL API SSL_CTX_load_verify_locations(ctx,CAFile,CAPath)
I receive:
Error Exception occurred message is error:0B07C065:x509 certificate routines:X509_STORE_add_cert:cert already in hash table
and the existing connections are terminated.
How can I do this update without duplication? Usually what happens if same .PEM file with CA list is loaded more than once using SSL_CTX_load_verify_locations()
