Method Detail

generate

public void generate(java.lang.String id,
                     java.lang.String owner,
                     int bits,
                     java.util.Random random)
              throws java.lang.IllegalArgumentException

Convenient method to generate a new key with certainty of primality equal to 1 - 1/2**1024.

Parameters:

id - the name to embed in the key.

bits - must be between MIN_RSA_MODULUS_BITS and MAX_RSA_MODULUS_BITS, inclusive. If this parameter is set to 0, this method will assume the default value of 768.

owner - the owner string for this key

random - the source of random numbers.

generate

public void generate(java.lang.String id,
                     java.lang.String owner,
                     int bits,
                     int certainty,
                     java.util.Random random)
              throws java.lang.IllegalArgumentException

Generate a new key. Port of gale_crypto_generate from gale.

Parameters:

id - the name to embed in the key in OWO order. This name should have the most specific part first. e.g. mail.jtr@ofb.net or *.pub@ofb.net.

bits - must be between MIN_RSA_MODULUS_BITS and MAX_RSA_MODULUS_BITS, inclusive. If this parameter is set to 0, this method will assume the default value of 768.

owner - the owner string for this key

certainty - a measure of the uncertainty that the caller is willing to tolerate: the probability that the number is prime will exceed 1 - 1/2**certainty. The execution time is proportional to the value of the certainty parameter.

random - the source of random numbers.

RSA_generate_key

private void RSA_generate_key(int bits,
                              long e_value,
                              GaleKeyGen.Callback callback,
                              java.lang.Object cb_arg,
                              int certainty,
                              java.util.Random random)
