BYOK Code Signing
Many application developers are increasingly reliant on expensive third-party cloud services for key management, handing control over keys to major cloud providers. This reliance can result in high costs, as cloud signing services charge for each signature and apply restrictive usage limits.
PKI Proxy empowers developers to retain control over their keys with secure, bring-your-own-key (BYOK) code signing, regardless of where the signing takes place.
Flexibly deploy PKI Proxy on-premises or self-host PKI Proxy and control secure access to it inside your own firewall. PKI Proxy is designed to work around your processes, not impose a process on you, and is ideal for teams whose developers and build servers are isolated from one another.
Leveraging powerful cross-platform integration capabilities and a secure communication stack, the private keys remain securely on a single machine under your control — while document or code signing operations can occur nearly anywhere.
With PKI Proxy, you can now bring your own keys (BYOK) for document or code signing, regardless of where the signing occurs. Utilizing our cross-platform, PKCS#11-compliant driver and client-server API, the private keys remain securely on a single machine under your control while document or code signing operations can occur nearly anywhere.
Comprehensive Code Signing Coverage
PKI Proxy provides comprehensive support for certificate kinds and origins, including:
- Hardware security modules (HSMs)
- File-based certificates (PFX files)
- Windows Certificate Stores
- USB hardware tokens, such as Yubikey and DigiCert tokens
Secure Code Signing
The private key never leaves your server, and PKI Proxy employs TLS to secure all communications. To protect remote key access, PKI Proxy supports multiple authentication options. Individual users are only provided access to specific keys as designated by your administrator, and all operations are logged. Built from the ground up using our own technology, PKI Proxy utilizes integrated security and provides an extremely small footprint.
