Class KeystoreManager

java.lang.Object

com.ibm.mm.sdk.security.KeystoreManager

public class KeystoreManager
extends java.lang.Object

Utility class for managing RSA keys in Java Keystore (JKS/PKCS12).

This class provides methods to:

• Create and initialize keystores
• Store and retrieve RSA key pairs
• Load keys from password-protected keystores
• Generate self-signed certificates for key storage

Usage Example:

 // Create a new keystore with RSA key pair
 KeystoreManager.createKeystore("config/keystore.p12", "keystorePass", "rsa-key", "keyPass");
 
 // Load keys from existing keystore
 PublicKey publicKey = KeystoreManager.loadPublicKey("config/keystore.p12", "keystorePass", "rsa-key");
 PrivateKey privateKey = KeystoreManager.loadPrivateKey("config/keystore.p12", "keystorePass", "rsa-key", "keyPass");
