方法详细资料

getAlgo

AlgoIdEnum getAlgo()

返回:

isEncryptor

boolean isEncryptor()

if contain public key list, return true.

返回:

isDecryptor

boolean isDecryptor()

if contain private key, return true.

返回:

setPkeyCipherList

void setPkeyCipherList(List<PkeyCipherBase> pkeyCipherList)

set public key list by PkeyCipherBase.

参数:

pkeyCipherList -

setPubkeyList

void setPubkeyList(List<Keypair> pubkeyList)

set public key list by Keypair.

参数:

pubkeyList -

setPrivkey

void setPrivkey(Keypair keypair)

参数:

keypair -

setPrivkey

void setPrivkey(PkeyCipherBase pkeyCipher)

参数:

pkeyCipher -

envelopeSeal

byte[] envelopeSeal(byte[] plaintext,
                    byte[] secretKey)

Digital envelopes encode function. broadcast to multiple users

参数:

plaintext -

secretKey - symmetry key for encode plainText. If it is empty, it will be generated internally.

返回:

envelopeOpen

byte[] envelopeOpen(byte[] ciphertext,
                    byte[] secretKey)

Digital envelopes decode function.

参数:

ciphertext -

secretKey - symmetry key for decode cipherText. If it is empty, it will be decoded from cipherText by privateKey.

返回:
