rsa

问题 There are many topics on RSA Encryption and Decryption using BouncyCastle, however I'm encountering some unexpected behaviour. I'm attempting to encrypt a 64 byte data blocking using a private key of size 64 bytes I compute the RSA Encryption as followings: public byte[] Encrypt(byte[] data, AsymmetricKeyParameter key) { var engine = new RsaEngine(); engine.Init(true, key); var blockSize = engine.GetInputBlockSize(); return engine.ProcessBlock(data, 0, blockSize ); } I compute the decryption

问题 i have been trying many answers on this Stackoverlow questions same like i am asking now, but still can't resolve my problem, i am trying to clone by ssh but always got Permission denied (publickey) when i run GIT_SSH_COMMAND="ssh -vvv" git clone git@bitbucket.org:myusername/my-api.git debug1: kex: algorithm: curve25519-sha256@libssh.org debug1: kex: host key algorithm: ssh-rsa debug1: kex: server->client cipher: chacha20-poly1305@openssh.com MAC: <implicit> compression: none debug1: kex:

问题 my first post. I'm trying to asymmetrically encrypt data in JavaScript (in the user's browser), using the existing public key that I've used to successfully encrypt data in our native iOS and Android app. I created the keys this way: openssl req -x509 -out public_key.der -outform der -new -newkey rsa:1024 -keyout private_key.pem -days 3650 (Thanks to http://jslim.net/blog/2013/01/05/rsa-encryption-in-ios-and-decrypt-it-using-php/) When I use these wonderful JavaScipt examples: Example.

问题 I am trying to initialize a Cipher object for encryption and decryption. String cipher = privateKey.getAlgorithm() + "/ECB/PKCS1Padding"; mCipher = Cipher.getInstance(cipher, "AndroidKeyStore"); I keep getting the following exception on android: System.err: java.security.NoSuchAlgorithmException: Provider AndroidKeyStore does not provide RSA/ECB/PKCS1Padding 03-20 00:28:38.270 19817 21488 W System.err: at javax.crypto.Cipher.getCipher(Cipher.java:357) 03-20 00:28:38.270 19817 21488 W System
