Field Detail

DEFAULT_NUM_PRIMES

public static final int DEFAULT_NUM_PRIMES

The default number of primes

Constructor Detail

MpRSAKeyGenParameterSpec

public MpRSAKeyGenParameterSpec()

Construct the default MeRSA key generation parameters. Choose the key size as RSAKeyGenParameterSpec.DEFAULT_KEY_SIZE, the public exponent as RSAKeyGenParameterSpec.DEFAULT_EXPONENT, and the exponent of the prime p as DEFAULT_NUM_PRIMES.

MpRSAKeyGenParameterSpec

public MpRSAKeyGenParameterSpec(int keySize)

Construct new MeRSA key generation parameters from the given key size. Choose the public exponent as RSAKeyGenParameterSpec.DEFAULT_EXPONENT, and the exponent of the prime p as DEFAULT_NUM_PRIMES. If the key size is invalid, choose the RSAKeyGenParameterSpec.DEFAULT_KEY_SIZE.

Parameters:

keySize - the key size (>= 512 bits)

MpRSAKeyGenParameterSpec

public MpRSAKeyGenParameterSpec(int keySize,
                                FlexiBigInt e)

Construct new MeRSA key generation parameters from the given key size and public exponent. The exponent of the prime p is set to the DEFAULT_NUM_PRIMES. If the key size is invalid, choose the RSAKeyGenParameterSpec.DEFAULT_KEY_SIZE. If the public exponent is invalid, choose the RSAKeyGenParameterSpec.DEFAULT_EXPONENT.

Parameters:

keySize - the key size (>= 512 bits)

e - the public exponent (must be odd)

MpRSAKeyGenParameterSpec

public MpRSAKeyGenParameterSpec(int keySize,
                                FlexiBigInt e,
                                int k)

Construct new RSA key generation parameters from the given key size and public exponent. If the key size is invalid, choose the RSAKeyGenParameterSpec.DEFAULT_KEY_SIZE. If the public exponent is invalid, choose the RSAKeyGenParameterSpec.DEFAULT_EXPONENT. If the exponent of the prime p is invalid, choose the DEFAULT_NUM_PRIMES.

Parameters:

keySize - the key size (>= 512 bits)

e - the public exponent (must be odd)

k - the number of primes (>= 2)
