在C#中,我能够通过以下任一方式对公钥进行哈希验证:
// Import from raw modulus and exponent
using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider()) {
RSAParameters rsaKeyInfo = new RSAParameters {Modulus = modulus, Exponent = exponent};
rsa.ImportParameters(rsaKeyInfo);
return rsa.VerifyHash(hash, CryptoConfig.MapNameToOID("SHA512"), signature);
}
// Import from XML
using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider()) {
rsa.FromXmlString(xmlPublicKey);
return rsa.VerifyHash(hash, CryptoConfig.MapNameToOID("SHA512"), signature);
}
我需要知道的是,在给定入站RSA公钥的情况下,如何使用CAPI完成同样的事情？
除了了解如何将公钥导入加密提供程序的上下文之外,我还有大多数验证哈希所需的CAPI函数:
HCRYPTPROV hCryptProv;
HCRYPTHASH hHash;
CryptAcquireContext(&hCryptProv, NULL, NULL, PROV_RSA_FULL, 0);
CryptCreateHash(hCryptProv, CALG_SHA512, 0, 0, &hHash);
CryptHashData(hHash, pDataToHash, lenDataToHash, 0);
CryptVerifySignature(hHash, pSignature, sigLength, NULL, CRYPT_NOHASHOID);
CryptDestroyHash(hHash);
CryptReleaseContext(hCryptProv, 0);
谢谢!
这个的后续。
我得到了阅读/解码工作
1> {ok, F} = file:read_file("inaimathi.rsapub").
{ok,<<"-----BEGIN RSA PUBLIC KEY-----\nmQINBE9NBIQBEADMSzN6b0FaPP0rGiLDWKfH4ehN66Z0SAIynXm6lBHjmO69pNsm\niIe4p1X9aXhr"...>>}
2> [Entry] = public_key:pem_decode(F).
[{'RSAPublicKey',<<153,2,13,4,79,77,4,132,1,16,0,204,75,
51,122,111,65,90,60,253,43,26,34,195,
88,167,...>>,
not_encrypted}]
根据文档，为了从中获取可用的公钥，我必须做的最后一件事就是在其public_key:pem_entry_decode/1上运行Entry。但是，当我尝试这样做时，会出现错误。

我在这里做错了什么？

我有一段简单的 JavaScript：

<script type="text/javascript">
var message = "This is my message"
// we create a new JSEncrypt object for rsa encryption
var rsaEncrypt = new JSEncrypt();
var publicKey = "-----BEGIN PUBLIC KEY-----" +

rsaEncrypt.setPublicKey(publicKey);
var encryptedMessage = rsaEncrypt.encrypt(message);
console.log(encryptedMessage)

我觉得每次运行时都应该在控制台中产生相同的输出，但事实并非如此。
示例输出：

谁能解释这种行为？
我已经成功创建了私钥和公钥，并对消息进行了编码，但是在解码消息时，我抛出了错误
到目前为止，我的代码是：
require 'openssl'
require 'base64'
key = OpenSSL::PKey::RSA.generate(2048)
pri_key = key
pub_key = key.public_key
string = 'Hello World!';
rsa_public_key = OpenSSL::PKey::RSA.new(pub_key)
encrypted_string = Base64.encode64(rsa_public_key.public_encrypt(string))
puts "Encrypted Message:"
puts encrypted_string
# This creates an error
my_string = pri_key.private_decrypt(encrypted_string)
puts "The decoded message"
puts my_string
打印编码后的消息后抛出此错误

我需要像这样转换以太坊地址
0xB34080739D5B656D76089f9f21b374BA5dafA373
像这样的公钥
e2d3a3a43e71eb541e12504cee22ed74024969b46b9e68ea7f9e5384fe96fc04
我是这样得到地址的
from web3 import Web3
w3 = Web3(Web3.HTTPProvider('https://sokol.poa.network'))
addr = w3.toHex(w3.sha3(text=public_key)[12:])
也许有一个图书馆可以做到这一点？请帮忙
我有两个带有私钥的服务器（实例），我想更改这些密钥而不停止服务器（实例）或创建新的密钥。
这可能吗？
