RSAMultiPrimePrivateCrtKey

AI-generated Key Takeaways

• RSAMultiPrimePrivateCrtKey represents an RSA private key using the Chinese Remainder Theorem (CRT) for multi-prime RSA calculations, as defined in PKCS#1 v2.1.

• It extends the RSAPrivateKey interface and provides methods to access CRT-specific parameters like crtCoefficient, otherPrimeInfo, primeExponentP, primeExponentQ, primeP, and primeQ.

• The interface also includes methods for retrieving the public exponent and the standard RSA key components like modulus and private exponent inherited from its parent interfaces.

• Developers can use this interface to work with RSA private keys that utilize the CRT optimization for faster computations in multi-prime scenarios.
