方法详细资料

addPublicKeyCipher

void addPublicKeyCipher(Set<String> keyNames,
 CryptoKeyReader keyReader)
                 throws PulsarClientException.CryptoException

抛出:

PulsarClientException.CryptoException

removeKeyCipher

boolean removeKeyCipher(String keyName)

getMaxOutputSize

int getMaxOutputSize(int inputLen)

Return the maximum for a given buffer to be encrypted or decrypted. This is meant to allow to pre-allocate a buffer with enough space to be passed as

参数:

inputLen - the length of the input buffer

返回:

the maximum size of the buffer to hold the encrypted/decrypted version of the input buffer

encrypt

void encrypt(Set<String> encKeys,
 CryptoKeyReader keyReader,
 Supplier<BuilderT> messageMetadataBuilderSupplier,
 ByteBuffer payload,
 ByteBuffer outBuffer)
      throws PulsarClientException

抛出:

PulsarClientException

decrypt

boolean decrypt(Supplier<MetadataT> messageMetadataSupplier,
 ByteBuffer payload,
 ByteBuffer outBuffer,
 CryptoKeyReader keyReader)
