问题 I'm trying to port the following Java code to a C# equivalent: public static String encrypt(String value, String key) throws InvalidKeySpecException, NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, IllegalBlockSizeException, BadPaddingException { byte[] bytes = value.getBytes(Charset.forName("UTF-8")); X509EncodedKeySpec x509 = new X509EncodedKeySpec(DatatypeConverter.parseBase64Binary(key)); KeyFactory factory = KeyFactory.getInstance("RSA"); PublicKey publicKey =

问题 i'm trying to encrypt and decrypt username in app using KeyStore, Using KeyPairGeneratorSpec to create the key in older version like 18 to 22, KeyPairGeneratorSpec as been depricated in version 23 of android M, But Android M supports KeyGenParameterSpec. Does this KeyGenParameterSpec supports backward comparability or how do i do this ? Im trying out some thing like this , is there any better solution for this. This works fine as off now! At the time of Ciper.getInstance in encryption and

问题 When generate a CSR using OpenSSL you have two options: 1) Generate a Private key when the CSR is generated 2) Use the private key to derive a public key and use the public key to create the CSR Does the CSR need to be signed with the matching private key for the CA to validate it? Hypothetically, what if i have TWO key pairs (PubKey1, PrivKey1, PubKey2, PrivKey2). First thing i do is move PrivKey1 to another place. Is there a way where I can use PubKey1 to make the CSR (Without access to

问题 I am trying to debug a simple openssl program but cannot quite get what openssl means with "oaep decoding error". I have reduced my program to this, test, one: #include <iostream> #include <openssl/evp.h> #include <openssl/rsa.h> #include <openssl/pem.h> #include <openssl/err.h> #include <assert.h> #include <memory> #include <list> #include <algorithm> #include <string.h> static const std::string private_key = R"(-----BEGIN RSA PRIVATE KEY----- MIIEogIBAAKCAQEAriDoH3gBbJo+SojeL5j

问题 For security, I encrypted some data, such as username, passwords, and emails in the browser by jsencrypt which is a A Javascript library to perform OpenSSL RSA Encryption, Decryption. And then I decrypt the cipher data using RSACryptoServiceProvider by C#. The public key, and private key are generated by c#： <RSAKeyValue><Modulus>wDIL9/5eXYZB1J6yOQSJTvczV6dv7/mF3X9p+86kWCArYQmNih/Y+ktOboAjo2UyC8np5Y81yF8G/qAdSrreIwdTtZyAFlgpij2Oovmqpg4/mzL7VS6Sj/4y34+GKRczTjDjxuqTmD4F
