SSL/TLS Certificate Chain Composer & CA Bundle Builder
Automatically resolve, verify, and complete missing intermediate Certificate Authority (CA) chains for leaf SSL/TLS certificates to eliminate browser SSL warnings.
Resolved Certificate Trust Chain
Composed Certificate Bundle (CA-Bundle)
Why Intermediate CA Chains Matter
Browsers require an unbroken chain of cryptographic signatures from a server's leaf certificate up to a trusted Root Certificate Authority. Missing intermediate certificates cause NET::ERR_CERT_AUTHORITY_INVALID errors in client applications.
Authority Information Access (AIA)
When an intermediate certificate is omitted, modern chain composers extract the Authority Information Access (AIA) extension from the X.509 header to automatically fetch the parent CA certificate URL over HTTP.
