RSAPrivateKey

AI-generated Key Takeaways

• RSAPrivateKey is an interface defining the structure of an RSA private key in Java security.

• It provides methods to retrieve the private exponent and modulus of the key.

• RSAPrivateKey extends PrivateKey and RSAKey interfaces, inheriting functionalities related to key management and RSA specifics.

• It also includes a serialVersionUID constant for compatibility across different versions.

• Two known subclasses, RSAMultiPrimePrivateCrtKey and RSAPrivateCrtKey, offer implementations based on the Chinese Remainder Theorem.
