问题 For my specific situation, I have to generate a RSA key pair (in my Android application) using the following codes :- KeyPairGenerator generator = KeyPairGenerator.getInstance("RSA/ECB/PKCS1Padding"); generator.initialize(1024,new SecureRandom()); KeyPair keyPair = generator.generateKeyPair); How can I import the keyPair into the Android keyStore ? I have been searching on the Internet for sometimes and did not get how can I create the self-signed certificate for the RSA public key for import

问题 I am using nimbus-jose-jwt 5.14 and I generated RSA key pair with the following code KeyPairGenerator gen = KeyPairGenerator.getInstance("RSA"); gen.initialize(2048); KeyPair keyPair = gen.generateKeyPair(); JWK jwk = new RSAKey.Builder((RSAPublicKey)keyPair.getPublic()) .privateKey((RSAPrivateKey)keyPair.getPrivate()) .keyUse(KeyUse.SIGNATURE) .keyID(UUID.randomUUID().toString()) .build(); Now I need to expone some "metadata" about the public key: e kid kty n use x5c How can I obtain x5c ?

问题 Innocently， I thought "SHA1withRSA algorithm" was simply operating the plainText with "SHA1", and use RSA/pkcs1padding to encrypt the result of "SHA1"。However, I found I was wrong until I wrote some java code to test what I thought. I use RSA publickey to decrypt the signature which I use the corresponding privatekey to sign with "SHA1withRSA algorithm" . But I found the result is not equal to "SHA1(plainText)", below is my java code: String plaintext= "123456"; Signature signature=Signature

问题 I need to store the server_key_rsa of my sftpServer in a docker-compose.yml but I don't know how to store it It's look like that for now : -----BEGIN RSA PRIVATE KEY----- ***********************My Key bla bla bla....... ********************************************** ********************************************** ********************************************** ********************************************** -----END RSA PRIVATE KEY----- And I would like to store it like that: server_key_rsa =

问题 I have public key in XML that created in C# the format is: <Modulus>rYDd94biRAJ1P6j68xjARl......and so on</Modulus> <Exponent>A**B</Exponent> I want to create this key in Javascript, and encrypt string with it, how can I do it? Thanks, 回答1: After so many hours researching, testing, giving up, researching again, etc., for a solution on RSA interoperability for .NET and Javascript, I have found this library: http://www.jocys.com/Common/JsClasses/Documents/ Their classes have the same working

问题 In PHP, I want to sign some documents with a padding of PSS, and a digest of SHA512. According to the docs, at http://www.php.net/manual/en/function.openssl-sign.php, I can set the digest however I need, by using a string, such as openssl_sign($text-to-sign,$binary_signature,$privkey,"sha512"); I don't see any way to set the padding, however. Can anyone please help me understand how I can sign text, using the RSA-PSS padding style, as seen in version 2.1 of PKCS #1? 回答1: In order not to be

Closed 2 years ago . Improve this question What is the different between RSA-OAEP and RSA-PKCS1.5? My understanding is they are both RSA encryption, but using different padding schemes. What is the advantage of one over the other? If I generate a RSA 2048 pirate and public key pair, can I use the same

问题 Before I get too much into the details, the high level thing I'm trying to accomplish is encrypting some data in JavaScript, sending that to a web server, then decrypting that encrypted data in C#. The part I'm having trouble with is decrypting the data in C#. I'm encrypting some data in JavaScript like this (I removed the extraneous code): // https://github.com/diafygi/webcrypto-examples#rsa-oaep---encrypt window.crypto.subtle.encrypt( { name: "RSA-OAEP" }, publicKey, data ) .then(function
