我可以使用Hyperledger Fabric v1.0中由MSP生成的公钥/私钥来加密/解密数据吗? [英] Can I use the public/private key generated by the MSP in Hyperledger Fabric v1.0 for encrypting/decrypting data?

问题描述

在Hyperledger Fabric v1.0中，可以通过MSP(会员服务提供商)在区块链网络中注册和注册用户.注册和注册后，将为用户提供一个公共密钥(在证书中)和一个私有密钥.据我了解，调用方使用私钥对事务进行签名，而对等方使用公钥来验证签名人.

In Hyperledger Fabric v1.0, a user can be registered and enrolled in the blockchain network through the MSP (member services provider). The user is given a public key (in the certificate) and a private key after registration and enrollment. The way I understood it, the private key is used by the invoker to sign the transaction, while the public key is used by the peers to verify the signer.

我可以使用相同的私钥和公钥来加密(使用公钥)和解密(使用私钥)吗?

Can I use the same private and public key to encrypt (using the public key) and decrypt (using the private key)?

如果是，我需要哪个Node.js库来使用MSP生成的这些密钥进行加密和解密?我尝试使用crypto软件包，但是它不起作用.它产生以下错误:

If yes, what Node.js library do I need to use these keys generated by MSP for encryption and decryption? I tried using the crypto package but it does not work. It produces the following error:

Error: error:0608B096:digital envelope routines:EVP_PKEY_encrypt_init:operation not supported for this keytype

我尝试在由OpenSSL(而非MSP)生成的RSA公钥/私钥对中使用加密包，并且加密/解密有效.

I tried using the crypto package in an RSA public/private key pair generated by OpenSSL (and not MSP) and the encryption/decryption worked.

推荐答案

Hyperledger Fabric 1.0.*不支持用于签名的RSA密钥.签名密钥必须是ECDSA密钥，因为这是当前唯一支持的类型.有关详细信息，请参见

Hyperledger Fabric 1.0.* does not support RSA keys for signing. Signing keys must be ECDSA keys as this is the only type that is currently supported. For details please see the documentation.
