RSAPrivateKeySpec

AI-generated Key Takeaways

• RSAPrivateKeySpec specifies an RSA private key using the modulus and private exponent.

• It provides methods to retrieve the modulus (getModulus) and private exponent (getPrivateExponent).

• RSAPrivateKeySpec is extended by RSAPrivateCrtKeySpec and RSAMultiPrimePrivateCrtKeySpec which include Chinese Remainder Theorem (CRT) information for efficiency.

• This class is used in conjunction with KeyFactory to generate RSA private key objects.
