问题 Code https://play.golang.org/p/CUEqjsJq5c Error: panic: crypto/rsa: message too long for RSA public key size goroutine 1 [running]: panic(0x4a6d80, 0xc420010420) /usr/local/go/src/runtime/panic.go:500 +0x1a1 main.main() /tmp/sample.go:28 +0xfa File size 811 byte (for test encrypt self source file). I want encrypt some bigger files, 1..500 mb. Can I do it with RSA or need use some other methods? 回答1: RSA can only encrypt data smaller than (or equal to) the key length. The answer is to encrypt

问题 With JSch I'm calling addIdentity() to add a private key and getSession() to open an SSH tunnel. When running this code locally on my Windows machine the opening of the tunnel is working. However when running that same code with the same private key on our CI the following error occurs: 2016-12-07 01:01:32 ERROR SSHConnector:25 - invalid privatekey: [B@4bb4de6a com.jcraft.jsch.JSchException: invalid privatekey: [B@4bb4de6a at com.jcraft.jsch.KeyPair.load(KeyPair.java:747) at com.jcraft.jsch

问题 I have some public/private encryption code written. It works fine when the data to be encrypted is short, example: "this is plain text". private static final String ALGORITHM = "RSA"; public static byte[] encryptWithPrivateKey(byte[] privateKey, byte[] inputData) throws Exception { PrivateKey key = KeyFactory.getInstance(ALGORITHM).generatePrivate(new PKCS8EncodedKeySpec(privateKey)); Cipher cipher = Cipher.getInstance(ALGORITHM); cipher.init(Cipher.ENCRYPT_MODE, key); byte[] encryptedBytes =
