Package org.bouncycastle.jcajce.interfaces

package org.bouncycastle.jcajce.interfaces

JCA-style key interfaces specific to BC's provider — e.g. BCFKSKey, MLDSAKey, XDHKey — letting callers downcast a Key from KeyFactory.getInstance(..., "BC") into the algorithm-specific accessor shape without depending on the concrete implementation classes.

Related Packages

Package	Description
org.bouncycastle.jcajce	Root of the JCA/JCE plumbing for BC: provider-overridable SecretKey implementations, PBE-key wrappers, and the CertStore bridge types that the BC provider's algorithms register against.
org.bouncycastle.jcajce.io	I/O streams that drive JCE primitives — MessageDigest, Mac, Signature, Cipher — as input or output streams, removing the boilerplate around feeding data into them by hand.
org.bouncycastle.jcajce.spec	AlgorithmParameterSpec / KeySpec implementations specific to BC's provider — covering PBKDF2 with extended digests, HKDF, ML-KEM / ML-DSA / SLH-DSA parameter sets, GOST key agreement, ZUC, SM2, EC implicit-CA, and other JDK-not-shipped algorithms.
org.bouncycastle.jcajce.util	The JcaJceHelper abstraction (default / named-provider / pinned-provider variants) used pervasively in .jcajce packages to make the underlying JCE provider selection a constructor argument rather than a global Security state lookup.
