Interface OpenSslCredential

All Superinterfaces:

ReferenceCounted

public interface OpenSslCredential
extends ReferenceCounted

Represents an OpenSSL/BoringSSL SSL_CREDENTIAL object.

SSL credentials provide a more flexible alternative to traditional certificate/key configuration, supporting features like:

• Multiple credentials per context (e.g., RSA + ECDSA)
• Delegated credentials
• OCSP stapling per credential
• Signed Certificate Timestamps (SCT)
• Trust anchor identifiers
• Per-credential signing algorithm preferences

This is a BoringSSL-specific feature. Use isAvailable() to check availability.

Instances are reference counted and must be released when no longer needed.
