Worker threads vs shared SSL_CTX: handshake latency under concurrent TLS load
A design is being evaluated where an application uses worker threads with libssl/libcrypto, a single process-wide SSL_CTX for configuration, and a separate SSL object per network connection. The goal is to keep TLS configuration immutable and shared while connection state remains per-connection. OpenSSL 1.1.0+ documents thread safety around the split between
opensslOpenSSL CRL Verification and Local Store Configuration
Certificate Revocation List (CRL) Validation OpenSSL provides the -crl_checks flag within the X509 verification store to ensure that certificates are checked against revocation lists during the chain validation process. A primary constraint is that OpenSSL does not natively perform network requests to fetch CRLs from Distribution Points (CDPs) defined in the
