Can Churchkey convert keys between different formats?

Yes, it is designed for format-agnostic decoding and encoding, making it easy to convert keys between formats like PEM and JWK with a single API call.

What key formats does Churchkey support?

Churchkey supports a wide range of formats including PEM (PKCS1, PKCS8, X.509), JWK (including JWK Sets), OpenSSH, and SSH2.

Is Churchkey compatible with standard Java security classes?

Absolutely. It provides a wrapper around java.security.Key and allows easy extraction and casting to standard JCE types like RSAPublicKey.

Does this skill support Elliptic Curve (EC) keys?

Yes, it supports over 100 curves, including NIST P-256, P-384, P-521, and secp256k1 via the Curve enum.

Parses, exports, and converts cryptographic keys across PEM, JWK, and SSH formats with automatic format detection.

Churchkey is a versatile Java library designed to simplify the management of cryptographic keys by providing a format-agnostic API for decoding and encoding. It automatically detects formats like PEM, JWK (RFC 7517), OpenSSH, and SSH2, allowing developers to seamlessly convert between them without managing the complexity of raw JCA/JCE classes. This skill provides Claude with the domain-specific knowledge to help you extract public keys, manage JWK Sets, and handle over 100 elliptic curves with standard Java patterns, making it an essential tool for secure backend development.
