public-key-encryption

I would like to know if someone know any library to do encryption in javascript and decryption in java. I have already tried many API, But getting not not getting same values in java. I want public-private key encryption and hence try to use RSA. Few i have used are: http://www-cs-students.stanford.edu/~tjw/jsbn/ http://ats.oka.nu/titaniumcore/js/crypto/readme.txt http://www.ohdave.com/rsa/ Few thing i checked, javascript breaks string into small chunks and then encrypt them which make cipher text different in java and javascript. I edit javascript code to use string as a whole but didn't

I want to encrypt data using RSA , I tried to generate the key in my code and it's working , But what I actually need is to get the public key as a string from server and then use it as Seckey so I can use it to encrypt data using RSA, I tried this code: //KeyString is the string of the key from server let KeyData = (keyString as NSString).dataUsingEncoding(NSUTF8StringEncoding) as NSData! var cert : Unmanaged<SecCertificateRef>!; var policy : Unmanaged<SecPolicy>!; cert = SecCertificateCreateWithData(kCFAllocatorDefault, KeyData); policy = SecPolicyCreateBasicX509(); var status : OSStatus =

I'm attempting to implement Diffie-Hellman key exchange. I am a little confused with how to use the secret key once generated. As seen in the output, the 2 secret keys are generated using the same prime & base as normal in the key exchange, and trade public keys when generating the secret keys, however they are not outputting the same value as I expected. I'm getting very confused with how to implement this encryption method and would be very grateful for some direction. My overall aim for this is to implement an encrypted SMS Android application. (The screenshot was unable to capture the

I have been able to setup the sharing of ssh-agent for public-key authentication after reading https://superuser.com/a/230872/301446 The environment file thus generated has the following contents: SSH_AUTH_SOCK=/tmp/ssh-OwqeSuxmEsQN/agent.4744; export SSH_AUTH_SOCK; SSH_AGENT_PID=8960; export SSH_AGENT_PID; #echo Agent pid 8960; And agent.4744 has: !<socket >24194 s 07DF88C6-E9997283-4C471010-2FE57D77 Would you know how this socket is used by ssh-agent? I can understand that it's used by ssh-agent to share authentication information but exactly how? From here : $SSH_AUTH_SOCK contains the path

I am trying to encrypt and decrypt a message as mentioned in the below code. Basically I want to encrypt a message with a public key and convert that encrypted message from byte array to String. And decrypt this string into original text. Here are the both methods. Here encryption works fine but decryption fails (error is "Data must start with zero"). I think this is causing because I convert encrypted byte array into String. How do I solve this? (I want to have encrypted byte array as string and use it for decryption) Is there any other approach (with public and private keys) public static
