split

public static java.util.Map<java.lang.Integer,byte[]> split(byte[] secret,
                                                            java.security.SecureRandom random,
                                                            int n,
                                                            int k)

Splits the given secret into n parts, of which any k or more can be combined to recover the original secret.

参数:

secret - the secret to split

返回:

a map of n part IDs and their values

join

public static byte[] join(java.util.Map<java.lang.Integer,byte[]> parts)

Joins the given parts to recover the original secret.

N.B.: There is no way to determine whether or not the returned value is actually the original secret. If the parts are incorrect, or are under the threshold value used to split the secret, a random value will be returned.

参数:

parts - a map of part IDs to part values

返回:

the original secret

抛出:

java.lang.IllegalArgumentException - if parts is empty or contains values of varying lengths
