问题 I use openssl in C++ , copy the PrivateKey and PublicKey file content to two const char*, but I see the demo of api is only get pem public/private key from a pem file,so how can I get a public/private key from a string? 回答1: Try this: char* mKey="-----BEGIN RSA PRIVATE KEY-----\nMIICXAIBAAKBgQCDT4ntP3Fqj73RQW32B6hCDHMG64GtxeQDZ5BcQnQSRB3S/EwM\ngpZwuGYwTb7E65pdAAQ0e5na2d7yIGZX4MoDRGaDbYgdxr49J430cVLRU1r9EW+O\nqZQERyGYefxWOqBaNZL2PBclS/qf+AxRh1WnD8aY5V5zNItgVV4Bv9w4YQIDAQAB

问题 I am trying o create a method that constructs an AsymmetricKeyParameter from a PEM encoded public key. Unfortunately, pemReader.ReadObject() return null. Here's a working solution for a private key: convert PEM encoded RSA private key to AsymmetricKeyParameter What is wrong with this method? static AsymmetricKeyParameter ReadPublicKeyFromPemEncodedString(string pemEncodedKey) { AsymmetricKeyParameter result = null; using (var stringReader = new StringReader(pemEncodedKey)) { var pemReader =

问题 I'm trying to create a PublicKey instance using an Oid and RSA public Key but I'm getting a CryptographyException with "ASN1 bad tag value met". I'm following the answer found here to eventually create a RSACryptoServiceProvider. Here's my code: string pem = @"-----BEGIN PUBLIC KEY----- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAkxqnUqh5WYis/Q+sQc5h O9i5aX7XvVEVdrhrnFcbwSb1/GyQWPvn1ZydQB88zW9CnNFq08QRg+IYaBYdqs12 EbxkET20eWY7xvI8kBICPxOdYAHBb0JWpdK4GjSCSxCFrJIXXmHtnRqj6PmSoPrb

Verifying XML Signature in Powershell with PEM Certificate

由 南笙酒味 提交于 2019-12-23 16:40:54
问题 I am trying to create a powershell script that will consume data with in a XML document. However, prior to doing any work I need to verify the XML hasn't been tampered with by verifying the signature. I have a copy of the public key for the cert used to sign the XML in PEM format, but I can not figure out how to get powershell to use that cert. The closes I have come to getting this to work is the following code... $Path = "data.xml" $Xmldata = new-object Xml.XmlDocument $Xmldata

rsa互通密钥对生成及互通加解密(c#,java,php)

摘要 在数据安全上rsa起着非常大的作用，特别是数据网络通讯的安全上。当异构系统在数据网络通讯上对安全性有所要求时，rsa将作为其中的一种选择，此时rsa的互通性就显得尤为重要了。 本文参考网络资料，提供了rsa互通性的一种可行的解决方案(c#,java,php),而这种互通性是在一定的局限性上达成的，比如密钥是1024位的(更高位没试过，应该也可行），基于PKCS1填充方式。 所编写的代码有一部分使用了硬编码，同时注重了功能的实现，在类结构设计上关注不多，有需要的可自行修改重构。 相关的程序集或包或代码请详见本文末尾附件。 一、生成互通密钥对 重点参考了Jeffrey Walton（ http://www.codeproject.com/Articles/25487/Cryptographic-Interoperability-Keys ） 1.c# using Cn.Ubingo.Security.RSA.Core; using Cn.Ubingo.Security.RSA.Key; //生成公私钥对 KeyPair keyPair = KeyGenerator.GenerateKeyPair(); //转换成不同的格式 KeyPair asnKeyPair = keyPair.ToASNKeyPair(); KeyPair xmlKeyPair = asnKeyPair

How to use .pem file with Python M2Crypto

问题 To generate an RSA key pair I used openssl: openssl genrsa -out my_key.private.pem 1024 openssl rsa -in my_key.private.pem -pubout -out my_key.public.pem Now I want to use this my_key.public.pem file in a function of another .py file: import M2Crypto from M2Crypto import RSA,SSL def encrypt(): pk = open( 'my_key.public.pem', 'rb' ).read() rsa = M2Crypto.RSA.load_pub_key(pk) print rsa; Am I doing it right? Both files are in same directory, but this function is not giving any output. 回答1:

Issue decrypting Alexa request signature using openssl_public_decrypt

由 早过忘川 提交于 2019-12-22 00:00:31
问题 I'm implementing a validator for validating incoming requests from Amazon Alexa. I'm on step 5 and 6 which state: 5) base64-decode the Signature header value on the request to obtain the encrypted signature. 6) Use the public key extracted from the signing certificate to decrypt the encrypted signature to produce the asserted hash value. I've managed to extract the public key from the PEM-encoded X.509 certificate by doing: $publicKey = openssl_pkey_get_public($pem); $keyData = openssl_pkey
