类 PrivateKey

java.lang.Object

com.arxanfintech.common.crypto.PrivateKey

所有已实现的接口:

Key

public class PrivateKey
extends java.lang.Object
implements Key

An EC Private Key, technically a big positive integer capable of signing such that the signature can be verified with the corresponding EC Public Key

另请参阅:

PublicKey

方法概要

限定符和类型	方法和说明
static PrivateKey	createNew(Cryptography crypto)
boolean	equals(java.lang.Object obj)
PublicKey	getPublic()
int	hashCode()
PrivateKey	offsetKey(java.math.BigInteger offset) Return a key computable for this key with an offset.
byte[]	sign(byte[] hash) Sign a digest with this key.
byte[]	toByteArray() Safe access to the key's internal representation

方法详细资料

createNew

public static PrivateKey createNew(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

getPublic

public PublicKey getPublic()

返回:

the corresponding public key

sign

public byte[] sign(byte[] hash)

Sign a digest with this key.

参数:

hash - arbitrary data

返回:

signature

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object

offsetKey

public PrivateKey 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
