构造器详细资料

PublicKey

public PublicKey(byte[] pub,
                 Cryptography crypto)

Create from uncompressed binary representation

参数:

pub - pub

crypto - crypto

方法详细资料

fromCompressed

public static PublicKey fromCompressed(byte[] pub,
                                       Cryptography crypto)

toByteArray

public byte[] toByteArray()

从接口复制的说明: Key

Safe access to the key's internal representation

指定者:

toByteArray 在接口中 Key

返回:

a copy of the key's internal representation

verify

public boolean verify(byte[] hash,
                      byte[] signature)

verify a signature created with the private counterpart of this key

参数:

hash - arbitrary data

signature - signature

返回:

true if valid

offsetKey

public PublicKey offsetKey(java.math.BigInteger offset)

从接口复制的说明: Key

Return a key computable for this key with an offset. Due to a homomorphic property of EC one may compute the offset key of both private and public keys independently such that they build a valid new pair.

指定者:

offsetKey 在接口中 Key

参数:

offset - offset

返回:

a key derived of this with an offset.

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object

equals

public boolean equals(java.lang.Object obj)

覆盖:

equals 在类中 java.lang.Object

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object
