About Certificate Bundles

Certificate bundles (also called CA bundles) are collections of trusted root and intermediate CA certificates used to validate certificate chains.

Common Use Cases:

Creating custom trust stores for Java applications
Configuring web servers to trust specific CAs
Adding corporate or internal CA certificates
Building certificate chains for SSL/TLS validation
ColdFusion cfhttp trusted certificate configuration

Format: This tool creates PKCS#1 PEM formatted bundles, which are compatible with most SSL/TLS implementations, including Java, Apache, Nginx, and OpenSSL.

Certificate Order: The order of certificates in a bundle can be important for some applications. This tool allows you to specify the exact order.

File Support: Supports both PEM (text) and DER (binary) certificate formats. Binary CRT/DER files are automatically converted to PKCS#1 PEM format.
